Broke my pc. Need some help

[Casual Cube]

Hey guys, I messed up.
I got a software to repair my pc like delete junk files, defragment the disks, malware detection, driver updates etc. 
Though, when I restarted after this, it gave me a nice BSD.

Error Code: Inaccessible Boot Drive

I tried everything I could find without any success. 
A few notes: Registry backup /dir gave me 0 results and dism wouldnt do any /online commands
I finally got my roommates laptop to get myself a win10 installation media but before I reset and lost files, I tried a fix from here
It asked me to "load hive" in regedit under a "new key", edit some things to say 0, which it already was set to, then unload hive.

After this, I restarted and it got worse, no more display, black screen only. Cant access anything and my fears are worsening. I should've hit reset.

Any one with knowledge of these issues, please offer some advice. I may be in trouble here.
I'll do the best I can to provide information based on my memory of the past 6 hours

Kiss everything on that drive good bye.

Do a clean erase twice.

Re-install windows.

How would I go about this?

Fortunately, I keep backups and nothing vital at all is on my primary drive. Would my other drives be needing cleaning as well though?

Some bios's come with secure erase built in.

Would flashing the bios be of any help here?

Update, i goofed.

There is display, but its just not going through my Displayport, when I used HDMI to another monitor, I'm getting a display output. But the same BSD error, nothing changed except gpu not outputting to DP.
Going to reset now using installation media and see what happens

no, you can leave those alone. i would unplug them when reinstalling Windows so you don't accidentially erase the wrong drive.

Unplug the drives you don't want and use the windows installation media to delete the partition on the main drive and create a new one to reinstall windows on. I usually do a fresh install about once a year to clean up the junk anyways, with Windows 10 its easy to do, and if you need a new windows key you can get oem keys for cheap.
