I was using my computer fine last night, and was wiping a spare internal HDD of mine, and then I turned my PC off and went to bed.
Then I got back from college and it was saying that BOOTMGR is missing press CTRL+ALT+DEL to restart. So I did this, many times without success.
So I got my Windows 7 installation disk and put it in and entered BIOS and chose boot from disk. This didn't work, it just leaves me on a black screen with a flashing cursor in the top left.
The Windows 7 was my only complete OS on my PC and now it's not booting from the SSD or my disk.
