I get this error:
Error: unknown filesystem. grub rescue>
I'm not exactly sure what I did. I believe I installed Ubuntu over Windows on my Acer netbook. I then tried to install Linux Mint, but it wouldn't start installing.
I turned the netbook off and back on. Now I get the error.
I have read a lot of other questions like this, but in my case I cannot boot a CD. If I put a Ubuntu CD or a Linux Mint CD into my external CD/DVD drive and change my BIOS to boot the CD-ROM first, it just gives me the same error screen.

Here are some results from my commands:
grub rescue>ls (hd0) (hd0,msdos5) (hd0,msdos1) grub rescue>ls (hd0,msdos5) unknown filesystem grub rescue>ls (hd0,msdos1) unknown filesystem grub rescue>ls (hd0) unknown filesystem
