I was recently given an Asus K55A laptop running windows 10. I was told to wipe it and do whatever I wanted with it. So, I used the restore function within windows 10, allowing it to delete files. I did this and it began a very slow reinstallation process where it froze for about 4 hours at 36% and 96%, when it froze, seemingly for good (12+ hours) at 99%. I called my father thinking he might have some input. He told me to shut it down, which I was hesitant to do, but so we did. He told me he’d take it for the weekend and fix it for me, so I gave it to him. Long story short, I now appear to have no OS and boot directly into BIOS. I have a flash drive with windows 7, but that doesn’t seem to work. I enabled CMS(?) and got some response from the drive and an error code. When using a flash drive with windows 10 on it, things appear normal except it couldn’t install due to MBR formatting? Per another bit of advice, I used diskpart to convert from MBR to GPT and I have certainly made it worse. Oh, to top all this off, I’ve been told that this laptop was never intended to support windows 10 and never should have been upgraded in the first place, so there’s that too. I don’t even know where to begin with this problem. I’m not even sure what was done to the laptop prior to my taking it back. I took it back because it was starting to sound like my dad was in over his head and now I’m in the same boat. All I want to do is set it up to dual boot with Linux mint and either windows 10 or 7. Any advice on what to do would be much appreciated.
