I thought when I burnt this image to a USB drive and installed Kali I thought I could simply take it out, and I could just boot my regular Windows 7 Home Premium OS without it. Now, without the USB drive at boot up, I get a no such device error, a few lines of code, and a grub rescue> prompt. When I installed Kali I was careful, but I think I may have somehow overwrittten the entire hard drive with it. The Kali Linux webpage even says "Oh, well you can just erase the files on the USB drive, and all your stuff will go back to normal blah blah) thank god I haven't yet because then I wouldn't be able to load any OS.
This is really bothering me I can't just use my Windows OS Puter without this friggin' thing in here. Can somebody please help me out? Should I download a Windows 7 HP install image to another USB?
