grubrescue

I'm currently using ubuntu 12.04 which has grub2 and wanted to install windows 8 from my USB, i also created a bootable usb flash drive using windows 7 dvd download tool, the problem is - I formatted my hard drive and whenever i try to boot from the flash drive i get an error "error: unknown filesystem" and gives grub rescue prompt, since my dvd drive is not working the only way for me to install win8 is from USB,can anybody help me with this?
