(not sure where to post this so I also posted it in another area)
So, I recently had some hardware installed on my PC and someone selected a previous version of Ubuntu while at the boot menu and then powered it off. When I started the PC I selected Windows 7 with no problem. I later Selected Ubuntu and saw some type of error and decided that I would just go back to Windows. After restarting the computer it went a black screen saying "grub error". I have no idea what to do now.
If anyone has any advice to fix my partitioned hard drive from "grub error" please help me.
A video would be ideal so I can see it at the same time, but I am in no position to be picky. I'll take what I can get.
