I was trying to dual boot Windows with Linux (linux installed first).

I read that it was easier to do so if windows was installed first. So I tried to install windows, by creating a partition for it.

There wasn't enough room on the drive so I tried changing the filesystem of my existing partition to support windows. Now whenever I try to start my computer I get the grub rescue screen.

I've tried booting from CD and USB with ubuntu and also with windows, but nothing happens.

I ran ls in grub rescue and got hd0, (hd0,msdos5), cd (with an install disc inserted), fd0, and fd1. However if I run ls on any of these I receive the error: unknown filesystem.

Can anyone help me out?
