Not that I'm planning to do this anytime soon, but just thinking about things. I'm in what seems like an unusual system configuration and so don't know what would actually happen.
Windows 10
Hardware supports TPM and CPU is "compatible" so Windows 11 will work on it - TPM currently disabled
Leagcy/CSM BIOS so no UEFI
Drives are not formatted using GPT
If I enabled TPM and UEFI and tried to run the Windows 11 update, what would happen? Would the installer convert the partitions to GPT successfully? Or what would happen?
I know I could take a copy (Macrium) of drives and try it, but it'll take time no matter what (and time is very precious here!) especially if I need to restore the system from backups.
Anyone any idea?
