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

Agreed, it's a common headache. One tip: temporarily disconnect or disable the Linux drive in your BIOS before running the upgrade, then reconnect it after.

Also, make sure your Windows Boot Manager is the primary boot entry in your BIOS after the upgrade.

Before we dig into that, have you tried temporarily disabling the Linux partition in Disk Management to see if the installer proceeds?

Yeah, that's a solid first step. Also, make sure your Windows Boot Manager is the active partition before you start the upgrade.

This. Just to be sure, have you already tried running the Windows Update troubleshooter?

+1 I had the same problem. I had to temporarily disconnect my Linux drive from the motherboard to get the Windows 11 install to complete. Good luck!
