I used to have Windows 8. I installed ubuntu (14.04 to be exact). Soon, ubuntu was messed up. So I tried to install a new system. I deleted the ubuntu partition and now whenever I try to boot my pc it comes up like this:

error: Unknown filesystem
entering rescue mode...
grub rescue>

NOTE: I do not have a system. But i have a Ubuntu and Windows 7 CD ready in case.

Of course! You erased the boot loader, so nothing can boot. you have two options:

  1. If you want to install Ubuntu again, just do it! That will install a new grub over the broken one!
  2. If you don't want to install Ubuntu, insert Windows 8 disk and repair the boot loader from it. I'm not sure if you can do it with Windows7 disk or not!
