Bootable USB Drive Not Showing Up or Recognized in Windows 10/8/7
The general steps to install Windows OS on a USB flash drive are like this:
- First, create a bootable USB flash drive.
- Second, download the Windows image on the bootable USB drive.
- To set up a computer to boot from a USB drive, go into the BIOS settings and set the USB as the boot priority, then choose to boot from USB.
The BIOS may not recognize the bootable USB drive if the drive is not properly configured or if the BIOS settings are not set to prioritize USB booting over other devices. Additionally, some BIOS versions may not support USB booting at all. It's also possible that the USB drive is not formatted correctly or is not in a compatible file system for the BIOS to recognize.
Why Doesn't the Bootable USB Drive Show up in the Bios
Here we have many thinkings on solving a bootable USB not working problem, which appears to be missing somewhere. You may perhaps have attempted to reconnect the USB installation media for several times, but why the computer still doesn't recognize it? Answers are now given.
1. USB Connection Issues Resulting from Loose or Broken USB Port
Solution - Try connecting the USB drive to every available USB port on a desktop or laptop, and if necessary, use a different working computer to rule out the possibility that the issue lies with a specific port.
2. Incorrect BIOS Settings
Solution - To make your computer boot from a USB drive, you need to configure the boot order in BIOS settings. This involves setting the USB drive as the priority boot sequence, allowing the computer to automatically select it as the boot device. By doing so, the BIOS can correctly detect the USB drive and use it to boot the computer.
To make a bootable USB drive show up in the BIOS, try specifying the boot order by entering the BIOS settings and setting the USB drive as the first boot device. This can usually be done by pressing a key such as F2, F12, or Del during boot-up, and then navigating to the boot settings.
- During the initial startup screen, press and hold one of the following keys: ESC, F1, F2, F8, or F10, depending on the BIOS manufacturer, to access a menu.
- To enter the BIOS setup and select the BOOT tab, you can choose to change the order of system devices, which appear in order of priority.
- To give a USB device boot sequence priority over the hard drive, move the hard drive device to the top of the boot sequence list, expand the hard drive device to show all hard drives, then move the USB device to the top of the hard drive list. This should allow the USB device to have boot priority over the hard drive.
- Save and exit the BIOS setup utility.
Some users suggest disabling Safe boot and changing the Boot Mode to "CSM" or "Legacy" instead of "UEFI" for potentially better results.
3. Making Bootable USB Flash Drive Is Unsuccessful
Solution - Have you checked whether your USB is really bootable or not? Some people didn't see a USB drive appearing in the BIOS boot menu only because the "bootable" USB drive they've created is not bootable at all! Especially by means of using cmd to create bootable USB drive without any software.
To resolve the issue of a bootable USB drive not showing up or being recognized in the BIOS boot menu on Windows 10/8.1/8/7, using a USB bootable software like Qiling Backup can be helpful. This software allows you to install Windows OS on a USB drive, ensuring 100% bootability on any other computer, effectively repairing a bootable USB flash drive that is not showing up, detected, read, or recognized.
Preparations:
- Make sure that your USB or flash drive has enough free space, larger than the system disk.
- Connect the USB to your computer.
Once you've prepared your Windows 10/8/7 installation media, you can start the cloning process. This involves copying or cloning your existing Windows installation to create a new, identical copy.
1. Launch Qiling Backup and click System Clone.
The system partition and boot partition will be automatically selected.
2. To clone Windows 10/8/7, choose the target drive (the USB flash drive) as the destination disk, then click on Advanced options and select Create a Portable Windows USB drive.
3. To start cloning Windows 10/8/7 to your USB, click Proceed. This will initiate the cloning process, which will create a bootable copy of your operating system on the USB drive.
