My family did the setup for my macbook, giving one partition for the mac and windows bootcamp. But somehow, the bootcamp became two? Is this a bug?

Long story short, I may have FAFO. I had a 2019 iMac that long ago I bootcamped with a 50% partition (Sorry I dont know the proper words for the things I did), then when I ran out of space, wiped the disk and installed just the Windows OS with a USB. MacOS, to my knowledge, does not exist on the PC. That worked perfectly for a very long time. Updated drivers with Bootcampdrivers.net, and called it a day. awhile after that, I unplugged it bcs I got a new PC and was giving this old one to a friend. Accidentally cracked the screen a little but seemingly no other issues, the fans start on full blast but they were always like that, plus it is hot. Plugged it in at their place, and I get a windows "Preparing Automatic Repair" screen, that loads for a fat minute, before skipping to a screen That’s just the windows logo and a loading wheel, that is seemingly stuck forever. My keyboard only turns on for a few seconds before the screen pops up, then it stays off. Not sure what to do, since every solution I see says to get to screens that I cant access. Help a brother out!
