Windows 11 install error: Windows cannot be installed to this disk
My Windows 10 PC sends me upgrade information from time to time and it seems the perfect time to upgrade to Windows 11 now as Windows 11 is much more stable and safe. So I made a Windows 11 bootable...

Why not change BIOS/UEFI settings if Windows 11 install error: Windows cannot be installed to this disk?
1. Access BIOS/UEFI:
- Restart your PC and enter the BIOS/UEFI setup by pressing a key during boot (usually F2, F10, Delete, or Esc, depending on your manufacturer).
2. Change Boot Mode:
- Look for an option related to boot mode. You may find options like "UEFI" or "Legacy".
- Change the boot mode from "UEFI" to "Legacy" or "CSM" (Compatibility Support Module).
Save and exit BIOS/UEFI settings.
3. Retry the Installation:
- Boot from the USB drive again and see if you can select the partition. This method allows the installation to recognize the MBR partitions without needing to convert it to GPT.
