Backout without booting harddisc?

How do I take backup on a harddisc that ain't booting? Need to backup the files, so I don't need to start everything on new. Because imma format my harddisc

put the hard drive in a second PC, copy files over. just be aware, if it's not booting the drive could be deadmetacritical

I will try on another PC. No, it is not dead, or it could be, no it's not. I got a bluescreen, then the HDD will not boot anymore, so imma stick with that it's a software issue.
