Question: HDD corrupted after using BootCamp
I've been trying to fix this for a couple of days and have tried to search everywhere will very little progress.
Basically my iMac ran great and I wanted to dual boot with Windows 10. So I followed some good instructions on how to install it using boot camp and everything went great!
Windows ran very well and I was satisfied. So I went back to my mac and instantly the load times were a bit suspect. As soon as I logged in it was horribly slow. I learned it could be because of spotlight indexing.
Long story short now I've erased the boot camp partition using disk utility (now realizing that was a bad thing to do) and erased my main drive and tried to reinstall High Sierra over night. It was stuck on "about a minute remaining" for hours. So I hit restart and it was the same as before. Apple logo with incredibly slow load time then right at the end the spinning reticle and black screen.
Erase the drive and reformat again but it fails at the end saying it cannot be mounted. I can never get a successfull first aid run on either the main drive or new formatted sub drive.
I'm really hoping it's not fried somehow.
