Case: Windows 10 Bootable USB not working

A Bootable USB is a media that contains everything required to boot Windows. Normally you can use it to start up your computer, whether it's bootable or not, and then clean install a fresh copy of Windows, perform in-place upgrade to Windows 10 from previous version, or troubleshoot a faulty computer. But sometimes you will find Windows 10 won't boot from USB drive, even no response, just like the following case.

I'm having problem with my Toshiba L875-S7308 where I cannot boot my USB while in UEFI mode.  I've formatted the USB (tried MBR and GPT), and restored the ISO using Windows 7 USB/DVD Download Tool. When I try booting from USB, the laptop ignores it and continues booting Windows. I've tried changing boot order, or manually selecting USB with no positive result.

Why Windows 10 bootable USB not working?

Windows 10 bootable USB not working issue may be caused by wrong boot mode or file system. Specifically, most of the old computer models supports Legacy BIOS while the modern computer like Windows 8/10 uses UEFI boot mode. And usually, BIOS boot mode requires NTFS file system while UEFI (CSM disabled) requires FAT32.

There are some other reasons may cause Windows 10 not booting from USB, please refer to the following scenarios:

  • Bootable USB is not detected as a boot device. This means your USB stick is either corrupted or unbootable itself, or USB boot is not supported on the computer. 

  • Bootable USB not showing up in BIOS. This may happen because of incrrect boot order. By default, your computer only boot from the first boot option. 

  • Bootable USB not showing up in boot menu. This is because your USB drive is old USB 1.0 or 2.0, which is not supported by Windows 10. 

  • You can't boot from USB in Windows 10, not even select the right boot option. In this case, the USB drive is likely to be damaged or corrupted. You may receive error message like "no bootable devices found".

▪ select disk n (“n” refers to the disk number of the USB flash drive that you want to format)
▪ list partition

▪ format fs=fat32 quick

Fix 2. Be sure the USB drive is set to be the first boot option

You can restart your computer, press the key (eg: F2, F11, ESC) on the first screen to enter BIOS, find out Boot Options or something like that and set boot priority to USB drive

If you cannot see the USB boot option, your computer may not support this option. You need to try different ways.

Fix 5. Create a bootable USB with Windows media creation tool

Up still now, if you don't fix Windows 10 bootable USB not detected or showing up via the given solutions, you can choose to create an installation disc with Windows 10 media creation tool provided by Microsoft's official website. Please follow the steps below. 

Download the media creation too first and then launch, select "Create installation media for another PC" and follow the on-screen instructions to complete this task.

Create Installation Media

Tip: Except for creating installation media, you still can create a bootable USB drive with built-in recovery drive (for detailed steps, see Windows 10 recovery disk). 

Now, you may already fix this error and have a bootable USB drive, so you can start to check if you can boot from USB in Windows 10 and then repair Windows 10 with bootable USB. The following is a simple guide for you.

1. Connect the bootable USB and set boot priority in the BIOS.

2. After the Windows files loading is completed, click Next until you see "Repair your computer" and tap on it.

Also, you can install SSD on Windows 10 with bootable USB, but the steps are slightly different. After booting from USB, you click "Install Now" instead of "Repair your computer" on the first Windows Setup interface. Then, just follow the prompt of the clean installation wizard.

That's the entire process of fixing Windows 10/11 bootable USB not working and how to use it. You certainly wouldn't use the fresh install method to get your computer back unless you want to abandon your operating system, installed programs, personal data, etc. The process is painful.

If you don't lose all of them, you can choose to repair your computer with the given recovery tools. If you have a system image on an external hard drive, you can solve 99% of computer issues. It contains everything of your system disk and you can restore system image to new hard drive on the current computer. 

But sometimes you may find this way is not working. For example, when you restore system image to a smaller drive, you will be told this disk is too small, please replace with a larger one. Then, you need the help of a professional backup software.

Quickly restore computer without reinstalling Windows 10

Except for installation media or built-in Recovery Drive, you can use a third-party media creation tool - AOMEI Backupper Standard to do a big favor when your computer is not behaving properly.

If you have higher requirement for backup security and flexibility, you can customize this task using "Options", "Schedule Backup", "Backup Scheme". And I'll introduce you to a few of the features I find most useful.
Schedule Backup: It allows you to set the fixed intervals to run the backup tasks automatically, such as Daily, Weekly, Monthly, Event trigger and USB plug in. And the last two are supported by the professional version.
Incremental Backup: It is able to backup only changed files since the last backup, which requires less backup time and disk space.
Backup Scheme(Advanced):  You can choose 3 different backup methods, except for incremental backup, you can also choose Full backup or Differential backup based on your own needs. And you can enable the backup cleanup feature to directly delete old backup regularly. This resolves the backup disk full issues completely.
