Here is the background of my issue:

I just recently installed the latest version of Ubuntu along side with Windows 8 Enterprise. However upon checking the disk size, it seems that some of the portions of the hd memory were gone so I decided to check the disk partition and have seen that is was being used by another file system. Thinking that the Ubuntu takes it boots stuff from my drive C: , I deleted that partition and formated so I can use it to store some movies, music etc.

Now, as I switch on my machine, I am stucked with:

error: unknown filesystem
grub rescue>

I googled a lot and saw the following command which seems no to me like sudo, chainloader etc, all of these command only returns unknown command in the console.

What I just wanted is to boot from my Windows 8 OS.

Just to add, I can't open the BIOS menu so I could choose what media to boot. As I open my machine it automatically takes me to grub rescue console.

Here are the thing I already have:

• Ubuntu Installation Disk
• Windows 8 System repair Disk

I just don't know how to boot into these things. Let me know what to do.
