Therefore, it is important to be able to do without using them in some situations.

If none of the options described in the article brings a positive result, you need to contact a specialized technical service, as this may signal a serious malfunction in the system. It is not worth experimenting with their solution on your own, because this can lead to an aggravation of the problem. It is better to immediately resort to the help of professionals.


In this case, the task is performed by working with the BIOS settings. You must follow these steps in sequence:

How to enable boot from a USB flash drive in BIOS on an Asus laptop

You can boot from a USB flash drive on an Asus laptop in two ways:

  • Through a combination of buttons to enter the BIOS;
  • Using the USB pushbutton.

Before booting from USB, the user needs to create a bootable disk. For this it is recommended to use the UltraISO program. The estimated amount of internal memory of a portable drive for a successful OS boot must be at least 4 GB, and the file system must be FAT32.

If initially the flash drive is in NTFS format, then it must be formatted. Right-click on the USB drive icon and select the “Format” line.

Normal BIOS setup

After loading the operating system and writing it to a USB flash drive as a boot disk, you need to go to BIOS.

Instructions for entering BIOS on an Asus laptop:

  • Turn off your laptop.
  • Press the power button. When the manufacturer icon appears, press and hold the F2 button for 5-7 seconds.
  • Wait for the menu to appear.

Navigation through the BIOS is carried out using the arrows on the keyboard panel. To accept values, use the Enter key, and to return them back. ESC.

On an Asus laptop, you can set the BIOS to boot from a USB flash drive as follows:

  • After going to BIOS, go to the Security tab. It is located in the top panel menu.
  • Opposite the line Secure Boot Control, select the value Disabled.
  • Next go to the Boot tab.
  • Turn on the Launch CSM function. Opposite it should be the value Enabled.
  • Use the Save Exit tab to save your changes. You can also use the F10 key.

If an old BIOS version is used (BIOS Award), then it is recommended to do the following to start:

  • Turn off your laptop. Press the power button.
  • When the manufacturer icon appears, press F2 or Del.
  • Go to the Advanced BIOS Features tab.

  • Below in the Boot Priority item, set External Device to the first place.
  • Go to Exit and select Save and Exit to accept the changes and restart your computer.

Why does not see the bootable USB flash drive and what to do

If the system does not see the bootable USB flash drive, then the problem may be as follows:

  • Launch CSM is not enabled;
  • ASUS Secure Boot has NOT been disabled;
  • The data was written to the drive incorrectly and the system does not read USB as a bootable element;
  • The file system has not been changed, NTFS is not always supported as a bootable flash drive.

It is recommended to use the Rufus software to correctly record the USB stick. It allows you to select the partition scheme and interface type for different motherboards.

Instructions for using the program:

  • Download the application from the manufacturer’s official website and install it.
  • Run the program. Next, you need to configure the parameters of the flash drive. Select in the first line the USB drive to be overwritten.
  • On the next line, select GPT with UEFI support.
  • At the bottom, check the box next to the phrase “Create bootable disk”. The case should be in ISO format. Click even more to the right on the disk icon and select the downloaded operating system in ISO format.
  • Make sure there is a check mark next to “Standard Windows Installation”.
  • Press start to start recording the image. Wait for the end and Remove the USB stick.

BIOS may NOT see USB if the drive is being used in a USB 3.0 port. A more proven option is to use an older USB 2.0 port. The rest of the problems during the download are not obligatory, especially if you strictly followed our instructions.

How else can you boot from a USB flash drive on a laptop?

Using a computer BIOS is not the only option. For example, it is possible to boot from a USB flash drive on a laptop asus, toshiba, samsung, etc. And through a special boot menu. It is called the Boot Menu (by the way, it is also part of the BIOS). You can enter it during the initial download phase. You just need to press Esc, F8, F11 or F12 quite often. Which key exactly depends on the motherboard developer and the BIOS version used in it.

Got into the Boot Menu, you need to select and install the boot from the USB flash drive using the arrows on the keyboard. Then all you have to do is press Enter. Agree, quite convenient and simple. However, it is not always possible to enter the boot menu. The fact is that on some laptop models the Boot Menu option is disabled in the BIOS. Therefore, additional actions are required to enable it.

Booting from a USB flash drive to BIOS: Step by step instructions

So, to put a boot from a USB flash drive in the BIOS on a laptop, you need:

  • Initially, connect the USB drive to the device. That is, we insert it into the usb connector.
  • We reboot the laptop. When enabled, press the Delete or F2 key. Depends on manufacturer, BIOS version and model. Sometimes you even need to press Esc, F1, Tab.
  • Disable Secure Boot Protocol. This is a special protection. It is also available in the UEFI BIOS, the most common version preferred by many modern laptop manufacturers. To disable it, select the Security section. Here we are looking for the Secure Boot term, in which we set the value Disabled (disabled). If this is not done, then the Corresponding Protocol will not allow you to boot your laptop from a USB flash drive. Priority will remain with the Windows installation disc.
  • We go to the Boot tab. Select the item Hard Drive BBS Priorities. We move our flash card to the first place in the list of boot devices (the hard disk automatically moves to the second). We also disable the “fast boot” option: in the Fast Boot line, select the Disabled value. If you see the Launch CSM item, then you need to switch it to Enable. In addition, quite often on a samsung laptop, there is an additional one in this window. OS Mode Selection parameter. It must be set to “CMS OS” or “UEFI and Legacy OS”.
  • Now press F10 on the keyboard. By the same, saving all the changes made.
  • If everything is done correctly, the laptop will start loading.

However, the BIOS versions are different for all manufacturers and laptop models. Therefore, the above procedure is NOT suitable for all devices. For example, if you go into BIOS and see a similar interface, then you have Award BIOS.

Then it will start the bootable USB flash drive like this:

  • Go to the “Integrated Peripherals” section.
  • Approximately in the middle of the screen, we find the item “USB Controller” with the arrows on the keyboard.
  • We press Enter. In the window, select the value “Enable”.
  • Please note that the line “USB Controller 2.0” also has “Enable”.
  • Press Esc. We leave this section. Then we go to Advanced BIOS Features. The name translates as additional or Advanced settings. Here we need the item “Hard Disk Boot Priority”.
  • We go in and see what comes first. There must be a flash drive, not a hard drive. Therefore, we select the USB-card and the button “” lift it up.
  • Press Esc. We select the term “First Boot Device” and set the value to “USB-HDD” (or USB-FDD, if the first option fails to boot from a USB flash drive into BIOS on a laptop).
  • Click Esc again. Select “Save Exit Setup”, then press the Y key.

There are also other versions of the BIOS. These are both Phoenix-Award BIOS and AMI BIOS. True, all of them are found only on old laptops with not the most “fresh” motherboards. How to configure booting from a USB flash drive to such devices? All the same. Only the names of the sections and BIOS menu items differ. The algorithm of actions and settings is as similar as possible.

How to boot a laptop from a USB flash drive via UEFI?

Many modern computing devices (especially those with the latest versions of Windows) come with a new boot interface. It is called UEFI. Working with this BIOS “variant” is a little easier. Plus, you can use the mouse here. However, despite the fact that the new interface is more understandable, not all users know how to work with it. Therefore, we will briefly describe the entire procedure.

For example, to boot from a USB flash drive on an HP laptop to UEFI, you need:

  • When booting the device, press the ESC key several times. Then F10 to get into BIOS Setup.
  • Now, at the very bottom of the window, find the Boot Priority section.
  • Just drag the USB flash drive icon to the first place.
  • Another option is to call it “Exit / Advanced mode”, then confirm the transition to the advanced mode by selecting the Advanced Mode item. Next, configure.

However, there are also quite a few UEFI versions. There are also Russified versions. As a rule, it is even easier to set the boot from a USB flash drive here:

  • First you need to go to the “Download” section. Sometimes it is made as a subsection. Then you should look for it in additional settings.
  • Just select the “Disc loading order”.
  • Prioritize the download to put the USB flash drive first.
  • Press F10. Save changes, restart laptop.

We will also talk about how to boot from a flash drive on devices with Gigabyte motherboards (they are preferred by many popular manufacturers. Acer, Lenovo, Samsung, etc.), on which UEFI BIOS is quite common.

  • We go into the BIOS. You already know how to do this. The easiest way. press “Delete”, “F2” or “Esc” at the initial stage of loading.
  • Then I “visit” the “BIOS Features” tab.
  • At the very bottom of the window, click on “Hard Drive BBS Priorities”.
  • In the line “Boot Option 1” you need to put our USB flash drive instead of the hard drive. Therefore, in “Boot Option 2” a hard disk should appear. HDD.
  • Save and exit.

How to boot a laptop from a USB flash drive

Quite often, laptop owners or users have to load the BIOS from a USB flash drive. Especially if the device has a CD / DVD drive, and you need to install a new operating system (OS) or install fresh drivers and Antivirus software. Therefore, in this article we will tell you in detail how to set the boot from a USB flash drive in the BIOS on laptops of various manufacturers (HP, MSI, sony, dell, acer, etc.).

Possible problems

At first glance, booting a laptop from a USB stick is not difficult. However, there can always be some problems. Therefore, we decided to describe the most frequent ones. In addition, we will tell you how to eliminate them.

  • Windows 7 laptop can’t boot from USB 3.0 stick? Indeed, this OS version does not support this standard without Special drivers. Therefore, the easiest way is to switch the USB stick to a different slot. Indeed, many laptops have both a 3.0 and 2.0 flash drive slot. It’s pretty easy to tell them apart. USB 3.0 connector has blue color (2.0. black) and two letters SS next to the port.
  • Do you press a variety of keys on your keyboard when you boot the OS, but still can’t get into the BIOS or Boot Menu? Then, when starting the laptop, pay attention to the inscriptions at the bottom of the screen. These are tips for the user. For example, the following may be written there. “Press F11 for Boot Menu”, “Press Del to enter Setup” or something similar.
  • You did everything right, but the bootable USB drive is still NOT recognized? There may be several reasons for this problem. However, more often than not, the whole point is whether the installation distribution was recorded incorrectly or the USB drive itself is faulty. It’s worth checking the flash drive on another device. It is better to record the software itself on a medium through DAEMON Tools or Alcohol 120%.
  • If you cannot boot a laptop from a USB drive using the boot menu, then you need to go into the BIOS. Here you need to make sure that the boot device priority is set correctly. To do this, we turn to the Boot tab. The flash drive should come first. If it is not, then highlight it and press F6. By the same, it will move to the first position.
  • Quite often on laptops with Windows 8 and 10, it is not possible to boot into the BIOS from a USB flash drive. Disabling the quick start function helps. To do this, go to the Control Panel. We select the section “Power supply”, then on the left we click on the item “Actions of the power buttons”. Next, uncheck the box that refers to “Enable Fast Startup”. It remains only to save all the changes.

How to boot from a USB flash drive ASUS laptop with UEFI BIOS

The other day they brought me an ASUS X541N laptop. They asked me to install Windows 10 or Windows 7 on it. I have a multiboot flash drive with different versions of operating systems, which I made a couple of years ago. I plugged this USB flash drive into the laptop, turned it on and began to press the Esc key on the keyboard. I thought I could quickly manage the Windows installation, but it didn’t work.
After pressing the Esc key, a window appeared prompting you to select a boot device. But my flash drive was not on the list. only the laptop’s hard drive was present. I went in this window to the item “Enter Setup”. Before me on the screen appeared the modern UEFI BIOS of the ASUS laptop. BIOS Utility. EZ Mode:

over, in the UEFI BIOS, my flash drive was displayed in the section “USB Port”, but in section “Boot Priority” it was NOT. This meant that I could not select it as a boot device and install Windows from it.

Then I decided to try changing the BIOS settings. I had done this before with a Lenovo laptop (that also had a UEFI BIOS). I will say right away: if it helped in the situation with Lenovo, then it was with this ASUS laptop that changing the settings did not work:

I moved to “Advance Mode”. in the Security section, the secure boot protocol was disabled (set the Secure Boot Control parameter to Disabled): Further, in the Boot section, the Fast Boot parameter was disabled: Then saved the changes and rebooted. After rebooting, I entered BIOS again in the Boot section.

But this section did not have and did NOT have an option “Launch CSM” (and no other similar, for example: “CSM”, “CSM Boot”, “CSM OS”, “Legacy BIOS “). In the second models of ASUS laptops, after activating this option in the Boot section, it became possible to boot from a USB flash drive.

Now I’ll tell you how I solved this problem and still installed Windows on an ASUS laptop:

Modern laptops have UEFI BIOS. In order to boot without problems from a USB flash drive in UEFI mode and install Windows on a GPT disk. this flash drive must be formatted in the FAT32 file system.

Therefore, if the BIOS of your computer does NOT recognize your USB flash drive as bootable, then first of all check what file system it has.

I inserted my flash drive into another computer. went into it “Properties” and saw that it was formatted with the NTFS file system:

Then I just cleaned it up and recreated the bootable Windows USB stick in the FAT32 file system.

After that, I reinserted it into the ASUS laptop. turned it on. pressed the Esc key on the keyboard several times. A window appeared with a proposal to choose a boot device. and this time, in addition to the laptop hard drive, there was also my USB flash drive. I selected it and started installing Windows. I didn’t even have to go into the BIOS and change something there. You can read about how to correctly create a bootable USB flash drive with Windows in this article of mine.

We set the boot from a USB flash drive on an Asus laptop

We go into the BIOS. For me, and most likely for you, this is the F2 key (if not, then try DEL too). Press it immediately after starting the laptop.

Next, go to the Boot tab and select the Hard Drive BBS Priorities item.

As you can see (in the screenshot below). I have a hard drive under Boot Option # 1. And under Boot Option is a flash drive. You need to install a flash drive under # 1.

To do this, click on Boot Option and select the USB flash drive. And the hard drive will automatically take second place.

You can go back to the previous menu by pressing Esc and you will see that under Boot Option a USB device is installed.

Don’t forget to press F10 and Yes to save the settings.

Everything, after restarting the laptop, boot from the USB flash drive should go (if it is created correctly).

If you did everything like me, then most likely, during the installation of Windows, after the reboot, the boot from the USB flash drive will start. And you need from drive C to continue the installation. I just pulled out the flash drive at the moment of overload. And when the download started from the C drive, I inserted it back (although, it seems like it is no longer needed for installation, the files have already been copied, but I could be wrong).

How to set the BIOS to boot from a USB flash drive on an Asus laptop? A few tips for installing Windows 7 from a USB 3.0 stick

Hello! Yesterday I got my hands on a new laptop ASUS X501A. It was necessary to install Windows, and everything you need, turnkey shorter :). I twisted it and found that it has a CD / DVD drive. And this means that you need to create a bootable USB flash drive and install Windows 7 from it. Also, the drivers for it on the disk are included, you also need to rewrite it to the USB flash drive. In general, it is strange, a laptop without a drive, and a driver on a disk. You need to put the driver in the kit on the USB flash drive, or an external drive :).

Anyway. I created a bootable USB flash drive. First, I created it using a special Windows 7 USB / DVD Download Tool (I wrote about this here). But I’ll say Looking at the front, for some reason the installation of Windows 7 from this flash drive did not work. Just blinking white cursor and tuning did not continue. I wrote down a bootable USB flash drive using UltraISO and it worked. Why so, they did not understand :).

That’s it, the flash drive is ready. Now you need to install the boot from this flash drive in the BIOS. Now I’ll tell you how to do it.

Possible problems installing Windows 7 from a USB 3.0 flash drive

You may have noticed that my USB drive has a new USB 3.0 interface. And Windows 7 supports USB 3.0, special drivers needed.

If the drive itself is USB 3.0, then it’s okay. Just plug it into a USB 2.0 port on your laptop and everything will work.

This is what the USB 2.0 connector looks like on a laptop:

And this is how the USB 3.0 connector looks like:

The third blue and two letters SS near the badge.

Well, if you have all USB 3.0, you will have to integrate the drivers into Windows 7. This is already a topic for another article. Perhaps I’ll write how to do it. In the meantime, you can find this information on the Internet.

You can also find and download an assembly with Windows 7, which already has integrated drivers for USB 3.0. There are such.

On this site there is probably all the information that may be useful for installing the operating system and for solving problems that may arise during the installation process. You can use the site search. And if you can’t find something, then ask in the comments, I will tell you :). Good luck!


Hey. Windows 7 (and earlier versions of Windows as well) has this.

Hello friends! All topics that relate to personal data, files and settings always.

Hello! When I was writing an article on How to install Windows 7 with.

Anyone who needs windows 7 installation images,
look for them on torrents, of which there are now a huge number of different.
Yes, many are blocked, but still people somehow use them,
use it too!

Man, God bless you! The only one who could help me! thanks!

I did everything as written. Does not boot from a USB flash drive. How and what to create a rule, or rather, how is it clear what to write?

Hello, in my BOOT tab the inscription HARD DRIVE BBS PRIORITIES does not appear on the ASUS X501A laptop model what to do in this situation if anyone has encountered such a problem please help in advance thanks

“In the BOOT tab, the inscription HARD DRIVE BBS PRIORITIES does not appear”.
Possible reasons:. The laptop is in UEFI mode. you need to switch to BIOS, look in the passport for the laptop.
Go to the Security settings and see what’s on / off and compare in pictures in this forum thread, there is a detailed description. who has BIOS version 2.15.

I wrote above here
“In BIOS, change the settings from UEFI, put others (I forgot what they are called).”
so, change the boot from UEFI to BIOS.

I bought ASUS R541s, I did everything correctly, the installation starts and then crashes what was not detected according to my words, the drive does not come out and tried to snag the system and install the drivers itself, but in any way everything that is on the Internet does NOT come out;.

I have a full fifth point. I have been friends with computers for a very long time) my uncle bought my sister a laptop asus x541sc. I did all the manipulations from the flash drive, I loaded them 2 (1 just normal windows 7 from off site 2 the same windows 7 but with usb 3.0 support) on both flash drives with clicking on the buttons The start of the installation asks for a drive on a CD dvd usb, I put everything in a USB flash drive and still rests on a corner! Both flash drives are made in UltraIso and both work great on the second 3 laptops! In general, 10 hours, I just don’t know what to do, I just don’t know mb there is advice?
PS There is no CD roma in the laptop at all if you connect an external one at all from it DOES NOT want to load anything

I myself am sitting with the same problem. But I figured out something. Drivers for USB from a flash drive are not readable after they have not yet been installed and the system “does not see” flash drive. Therefore, the USB drivers must be downloaded to the hard disk and installed from it when the Windows installation program requests them. I have a problem that I cannot find the necessary drivers for this Asus on Windows (on the intel site they are all packed).

How good it used to be. I wrote down Windows to a hard drive in another partition and, if necessary, then reinstalled it at any time.

Problem with hard disk partitioning style (GPT). Your review does not describe how to solve the problem.

ASUS x540s laptop was purchased without people. I’m trying to install 7k, wrote down a bootable USB flash drive, put everything in the BIOS correctly, sees the USB flash drive and starts loading, but after unpacking, a blue screen of death comes out with an error 0x0000007E. I wentogle an error, there are many reasons, but I did NOT find it specifically for my malfunction. The problem is not in the flash drive because it works on another laptop from this flash drive. Please help me what’s the problem

Little information.
If the installation image contains tools for working with HDD,
make the disk standard, that is, in the MBR. I think that this error is due to the BIOS settings, perhaps there is a function for working in the HDD in UEFI mode. Seven not be friends with UEFI.
Try different BIOS settings.
