Windows 10: Recovering data after reinstalling windows

so a month ago, I reinstalled windows after accidentally cleaned my hard drive because I ran into death error and usually restore points work but it wasn't working this time, and my laptop appeared as "boot device not found" so I installed windows. I was wondering if backups would be available because I do remember putting up a backup in command prompt. I don't know if this is still available. The thing is I also lost my hard drive so I can't do nothing and I'm out of idea's.

Windows 10 won't boot, repair, recover or reinstall

Thank you, Gerard! I appreciate your help.

I tried using Win 10 boot media to reinstall from scratch. Install chugs away for a while then shows me a list of partitions on my hard drive. No matter which I select, Windows can't be installed because they're GPT partitions.

I've also tried running chkdsk /r /x as suggested in another post. That seemed to run without any problems, but when I restarted I eventually got a blue screen with error 0xC0000021a.

At this point it's looking like I need to completely reformat the disk and reinstall Windows from the boot media. Is that the next step? I've recovered my data - which is all still accessible.
