I’m trying to upgrade my Windows 10 to 11 on my dual-boot system (with Ubuntu), ?

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.

Agreed, that fixed it for me too. One extra thing: make sure you're booting into Windows directly from the BIOS menu when you run the installer, not through the GRUB bootloader.

Same here. You could also try temporarily disabling Secure Boot in your BIOS, as that sometimes conflicts with the installer on dual-boot setups.

This. You could also try running the Windows Update troubleshooter first, since that error code often points to a corrupted update cache.

Agreed. Also, make sure your Ubuntu bootloader isn't interfering by temporarily setting Windows as the default boot drive in your BIOS before starting the upgrade.

+1 Yeah, that's a solid point. One extra tip: if you're using BitLocker, suspend it before the upgrade to avoid any encryption-related hiccups.
