I'm trying to upgrade my Windows 10 PC to Windows 11, but I have a dual-boot set?

Another option is to temporarily disconnect the Linux drive in your BIOS during the upgrade, then reconnect it after.

Have you checked if the Windows partition itself has the full 64GB of free space required for the upgrade? Hope that helps.

Can confirm. Yeah, that's a good point. Also, make sure your Windows drive is set as the primary boot device in your BIOS before starting the upgrade.

This. Agreed, that's a solid approach. Yeah, and just make sure you've backed up anything important on both systems before you start tinkering with the bootloader.

You could also try temporarily disabling the Linux boot entry from within Windows using a tool like EasyBCD, then running the upgrade.
