Windows 10

Usually, if it's a hardware problem, a simple cleaning would do the work, but I still need a response from your end to conclude anything.

Using a Windows bootable disk is the best thing.
In fact, before it, I would suggest that you do a clean Windows OS install, because you don’t know what is wrong with your computer.But this is a bit risky,as the data on the computer will disappear after you install a clean OS.

The blue screen indicates a bad hard drive and actually all hard drives fail so whenever your system tries to boot even if you select the launch startup repair option or start windows normally it will still show you blue screen i.e. the hard drive is bad. You need to replace the hard drive and reinstall your OS with your backups.
