Hi, I have a problem when i was trying to format an usb drive, accidentaly I formatted another thing (/dev/sda1) and the system created another media drive, but when I restarted my computer I only see the black screen saying error unknown filesystem (I think that only the grub was deleted) I have already try ls set prefix... insmod normal with all options displayed in ls, but nothing. Is there any easy way to reinstall the grub in /dev/sda1 and start normally my system? thanks.

What lets you think that you only deleted grub? You are on a system with BIOS firmware, correct? I rather think you may have formatted your boot partition. I would boot a Fedora Live CD and check what exactly is left of your system. If /dev/sda1 was your /boot you will have to do more than reinstalling grub since you are missing the initramfs images (and more...)

Have a look at and follow my steps there. Just replace "23" by "22" in this comment ;)
