So uh, ill try reinstalling windows 10, ill go for a backup incase something goes wrong, Is there any recommendation for drive cloning software? Will the tool from microsoft delete some files?
You know what, i'll do it like this: I'll keep this OS install on this current HDD, I'll get 2 more drives, 1 for backup of this HDD, other for the fresh OS install.
In safe mode it booted in about 5 minutes, I also got the windows update error again. This time not NET framework, something like OS Build update, I do not know how to translate it correctly from polish.
Succesful! The windows update error was fixed. By the way, i found out that windows boots in 40s-1m but the Please wait screen takes 15 minutes to get over.
Might take some time, I also am paranoid sometimes that i will lose data if i do something with powershell, cmd on admin, etc, might be because my old pc's HDD failed after doing a health check.
