Is this a common issue before updating to Windows 11?
I recently purchased a computer through facebook marketplace for a reasonable price, fully working. Upgraded the motherboard, CPU, and ram to a more modern spec.
I decided to update from Windows 10 to Windows 11, Secure Boot mode disabled. Here were the following issues:
Secure Boot won't enable
Because CSM is on
CSM can't turn off
Because drive is MBR, not GPT
Windows boot files are on the wrong disk
EFI partition missing/wrong
Need partition conversion
BIOS no longer detects boot properly
Need new boot entry / Secure Boot keys
Using a slew of reddit forums and obscure website forums, in combination with some Al guided assistance, i managed to fix the issues without bricking my PC and complete the update to Windows 11. I have only a small amount of computer knowledge, and this was one of the most mentally intensive, nerve-wracking tasks i've ever had.
Is this a common issue, and should i have just paid a technician to repair the issues without poking around?
Tldr: Disabled Secure boot mode causing chain of problems, 3 hours of troubleshooting and fixes before update possible.
