Yeah, that worked for me too. Just a heads up, you might need to reinstall or repair GRUB from a live USB after the Windows 11 upgrade is done.

This happened to me. I had to temporarily disable the Ubuntu partition in Disk Management from within Windows 10 before the upgrade would finally go through.

Can confirm. Did you remember to disable Secure Boot in your BIOS before trying the upgrade?

Yeah, I had the same problem. For me, it was actually the other way around—I had to enable Secure Boot and TPM in the BIOS, not disable it.
