Create Debian Bootable USB on Windows 11 for Installation on another laptop?

You can manually use the built-in Diskpart tool to prepare the USB drive and xcopy to copy the Debian ISO.

How to Create Debian Install USB with Windows 11

1. Open Command Prompt as Administrator.
2. Type diskpart and press Enter to open the Diskpart tool.
3. Enter 'list disk' to see a list of disks connected to your computer.
4. Identify your USB drive by its size (e.g., Disk 1) and type select disk X (replace X with the number of your USB drive).
5. Input 'clean' to erase everything on the USB drive.
6. Type 'create partition primary' to create a primary partition on the USB.
7. Enter 'select partition 1' and then active to mark the partition as active.
8. Type 'format fs=ntfs quick' to format the USB drive.
9. Input 'assign' to assign a drive letter to your USB.
10. Close Diskpart by typing exit.
11. Mount the Debian ISO file (you can use a tool like 7-Zip to extract it or just mount it in Windows).
12. Copy all the files from the Debian ISO to the USB using xcopy:

xcopy /s /e /f X:\*.* Y:\

Replace X: with the mounted ISO drive letter and Y: with the USB drive letter.

After this, your USB should be bootable and ready for installing Debian.
