Why create a Windows 11 repair USB?
Windows 11 has been around for a time, and despite varied reviews and criticism, many users have used it since its debut.
Some people may already meet some issues that result in a system boot failure. In most circumstances, when the Windows 11 OS fails and the PC strangely begins to operate slowly, the first choice will be to look for solutions online. You might be able to find an effective solution to this problem.
But if this does not work, the last step should be to reinstall the operating system. What if your PC lacks an optical drive or the original installation CD/DVD is no longer available?
In this case, a repair USB is an excellent option, as it also allows you to reinstall Windows 11 using a USB drive. In a nutshell, the USB stick is portable and works with practically all PCs and laptops. Furthermore, installing the operating system or repairing system issues via a USB device is more convenient than using other tools like CD or DVD.
2 ways to create a Windows 11 repair USB
In this section, we have two methods for creating a Windows 11 repair USB stick. The first is to use CMD to make a USB that serves as both a repair and an installation USB. The second method is to use a third-party program to build a repair tool to repair system problems.
Method 1. Using CMD to create Windows 11 repair USB
· Download the Windows 10 ISO files from the official site
· Make sure the USB flash drive has at least 16GB of free space.
Step 1. Press “Win”+ “R” at the same time to open the “Run” dialogue. Input “cmd” and hit on the “Enter” key.
Step 2. When the Command Prompt opens, type “diskpart” and press “Enter” to launch the DiskPart.exe tool. Then execute the following command in sequence.
list disk
select disk #
clean
create partition primary
select partition 1
format fs=fat32 quick (Windows 11 requires UEFI boot, only fat32 can be used in this command.)
active
After you format the USB flash drive, please type “Exit” to close the diskpart.exe. Then use File Explorer to copy and paste the entire contents of the Windows ISO to the USB flash drive.
If the Windows image file is over 4GB, you will fail to copy files onto the USB, because it surpasses the file size limit of the FAT32 file system. Once it happens, do as below:
• Copy everything except the Windows image file (sources\install.wim) to the USB drive, either dragging or dropping. Or use the command: robocopy D: F: /s /max:3800000000 (D: is the mounted ISO and F: is the USB flash drive.)
• Split the Windows image file into smaller files, and copy them onto the USB drive:
Dism /Split-Image /ImageFile:D:\sources\install.wim /SWMFile:F:\sources\install.swm /FileSize:3800
Some users might also have question about “How do I run Windows repair from USB?”, don’t worry, we’ll show you.
Step 1. Plug your USB in the port and turn on your computer and enter the UEFI interface, here you need to select the USB as the boot device.
Step 2. Then, you’ll see the Windows Setup window. Please set all language, time, and keyboard information.
Step 3. When you see “Install now”, please click the “Repair your computer” to enter the repair environment.
Then you can choose the needed option. “Troubleshoot” offers advanced repair tools like CMD and automatic repair option.
You can choose one to fix your problem.
