Has anyone else had boot issues after trying to upgrade from Windows 10 to 11? M?

Agreed. You could also try booting from a Windows 10 USB and using the startup repair tool. Another option is to check if your drive controller mode in the BIOS is set to AHCI and not RAID. Let me know if that works.

This. Yeah, that startup repair can really save the day. Also, if you have a spare drive, a clean install there can help rule out hardware issues.

Yeah, Before you try that, have you checked if your BIOS is set to UEFI and not Legacy/CSM mode? Let me know if that works.

You could also try booting from your Windows 10 install media and running the startup repair tool. Another option is to check if you have any incompatible drivers, especially for older storage controllers.

Yeah, You could also try temporarily disconnecting any non-essential USB devices before booting. Another option is to go into your BIOS and make sure your boot drive is still set as the first priority.
