How To Do an ASUS Boot From USB flash drive

How To Do an ASUS Boot From USB flash drive

If you need to do a boot because you need to reinstall windows, or perhaps you need to roll back to an earlier version, we can help.  In this guide, we will show you how to do an ASUS boot from usb flash drive.

In general, the algorithm repeats the method that is identical for all, but there are several nuances that we will explore later.

  • Of course, you need the boot drive itself. Methods for creating such a drive are described below
  • The next step is to configure the BIOS. The procedure is simple, but you need to be extremely careful.
  • Next is the direct download from an external USB-drive. Provided that you did everything correctly in the previous step, and did not encounter problems, your laptop should boot correctly. 

    ASUS Laptops have gained popularity for its quality and reliability. Devices of this manufacturer, like many others, support booting from external media, such as flash drives.


    Today we will review this procedure in detail, as well as get acquainted with possible problems and their solutions.

Configuring BIOS on ASUS laptop

BIOS is the basic system of user interaction with the computer.

She is responsible for checking important components of the device for operability at boot time, and with its help.

You can somewhat expand the capabilities of your PC if you make the correct settings.

How Important is Setting Up the BIOS

It all depends on whether you bought a fully assembled laptop/computer or assembled it yourself. In the latter case, you need to configure the BIOS for normal operation.

Many purchased laptops already have the correct settings, and there is an operating system ready for work, so there is no need to change anything in it, but it is recommended to check the correctness of the parameter set from the manufacturer.

Setting up on ASUS laptops

Since the manufacturer has already made all the settings, it remains for you to check only their correctness and/or adjust some for your needs. It is recommended to pay attention to the following parameters:

  1. Date and time. If you change it, it should also change in the operating system, but if time is entered in the computer via the Internet, then there will be no changes in the OS. It is recommended to fill in these fields correctly, as this may have a certain impact on the operation of the system.
  2. Configuring hard drives ( “SATA” or “IDE” ). If everything starts up normally on a laptop, then you shouldn’t touch it, because everything is set up correctly, and user intervention may not affect the work in the best way.
  3. If the design of the laptop implies the presence of drives, then check whether they are connected.
  4. Be sure to see if USB interface support is enabled. This can be done in the section “Advanced,” which is in the top menu. To see a detailed list, go from there to the “USB Configuration.”
  5. Also, if you consider it necessary, you can put the password on the BIOS. This can be done in the “Boot” section.



In general, on ASUS laptops, BIOS settings are no different from the usual ones; therefore, checking and changing are done just like on any other computer.

Unlike many computers and laptops, modern ASUS devices are equipped with a special system to overwrite protection – UEFI.

You will have to remove this protection if you would like to install some other operating system, for example, Linux or older versions of Windows.

Fortunately, it is easy to remove the protection – you just need to use this step-by-step instruction:

  1. Go to “Boot,” which is on the top menu.
  2. Further in the section “Secure Boot.” There you need in front of the parameter “OS Type” put “Other OS.”
  3. Save the settings and exit the BIOS.

On ASUS laptops, you need to configure the BIOS in rare cases, for example, before reinstalling the operating system. The remaining parameters for you set the manufacturer.

If there are any problems, read below.

Solving possible problems

Alas, not always the boot process from the USB stick on the ASUS laptop is successful. Let us examine the most common problems.

BIOS doesn’t see the flash drive

Perhaps the most common problem with booting from a USB drive. However, on some models of laptops (for example, ASUS X55A ) in the BIOS there are settings that need to be disabled. This is done like this.

  1. Go to the BIOS. Go to the tab “Security,” we reach the point “Secure Boot Control” and disable it by selecting “Disabled.” To save the settings, press the F10 key and reboot the laptop.
  2. Boot into the BIOS again, but this time select the “Boot” tab.

In it, we find the “Launch CSM” option and enable it (the “Enabled” position ). Press F10 again and restart the laptop. After these actions, the flash drive should be correctly recognized.


The second cause of the problem is typical for flash drives with recorded Windows 7 – this is an incorrect partition layout scheme.

For a long time, the main format was MBR, but with the release of Windows 8, GPT occupied the dominant position.

To deal with the problem, rewrite your flash drive with the Rufus program, select the option “MBR for computers with BIOS or UEFI” in the item “Scheme and type of system interface,” and install the file system “FAT32”.

The third reason is a problem with the USB port or the USB flash drive itself. Check the connector first – connect the drive to another port.

If the problem is observed, check the USB flash drive by inserting it into a known working connector on another device.

During the boot from the flash drive, the touchpad and keyboard do not work

Rarely encountered a problem characteristic of the latest laptops. Solving it to the absurd is simple – connect external control devices to free USB connectors.

As a result, we note that in most cases, the boot process from USB flash drives on ASUS PDAs runs without failures, and the problems mentioned above are rather an exception to the rule.
