So I‘ve tried to get my PC ready for Windows 11 because I wanna get it in the next month or two. Windows 10 complained and told me that secure boot and TPM 2.0 are missing. After Switching the TPM config to PTT that issue was resolved, but the Secure boot persisted, Windows Website told me to disable Legacy Boot from the CSM settings but that made the PC only boot to BIOS/UEFI, I fixed it by undoing my changes and searched the Internet for a solution. Apparently my C: disk is still in MBR not GPT, (I‘ve Installed Windows 3 Years ago on this machine) solutions like mbr2gpt didn‘t work, so Windows support articles once again recommended running cod of of the win 10 Recovery launched via the settings, since I‘ve done that my System keeps screaming there‘s no OS detected and that I should Remove non OS Drives. I have 3 drives on the machine with the one with C: being partioned once into C: and D: one thing I realized was that C: was Drive 2 and no longer Drive 0 after the CSM shenanigans (I saw it in windows 10 drive manager) Currently there‘s no way for me to Boot into Windows, I can go into BIOS but I‘m not sure what to do, because I don‘t wanna start removing drives RN, so I‘d be very very thankful for any help.
Edit: So I‘ve also clicked „set partition active“ in the drive manager it warned me but I selected C: the partition with the OS
