Grub Rescue: no such partition

[AligatorBlud]

My computer does not have a working CD rom drive, so I had booted from USB (used UNetbootin to make the USB) to install Ubuntu initially. I had Ubuntu working on my laptop (Gateway 7330gz), started messing around with it, and decided I wanted to start fresh again. So after searching the web for a how-to on reinstalling I thought I understood that I should hide or delete the partition that was selected to boot from. Now, after deleting this partition, when I boot this is all that comes up:

GRUB loading.
error: no such partition
grub rescue>

My CD rom drive does not work, and for some reason it won't read from the USB anymore, so I can't boot from anything. The only commands for the rescue mode that I've found to work are ls and set but they are the only two I know so far. I'm hoping there's a way to manually tell it to boot from the usb from this rescue mode. When I type in ls i get:

(hd0) (hd0,5)

and when the usb is plugged in it adds (hd1) (hd1,1)

When I type in set i get:

prefix=(hd0,1)/boot/grub
root=hd0,1

Pllllleeeeeeaaaaaseeeeeeee help

Oh, a few other things:

-Ubuntu was installed as the only thing on the hard drive. Windows was completely erased.

-curiosity killed the linux box

Hi and Welcome !

There should be an option in BIOS to set USB device as First Boot Device. Select that option, boot up from USB of any Linux distro and wipe harddisk.


There is no need to hide boot partition. You can install as many Linux distros as you like. Just shrink existing partition, create new and install Linux in it. Linux installer detect other installed distros pretty well and setup dual/multi boot itself.

I've tried to change the BIOS settings but it doesn't do anything. For BIOS options I have IDE HDD, FDD, and CD/ROM. None of them work, I'm pretty sure I've tried every combination of them too. When the computer boots the Flash drive lights flash but then it just goes straight to the GRUB rescue thing. I've read that if there is a Linux partition on and you don't make room for anything else that it won't boot from a CD or USB, and I didn't do anything besides delete the flagged boot partition before everything got messed up. Now I don't know what to do. I can't even use dban because the computer won't boot from anything. I should have been more patient...

How come you can boot from USB Device if your computer BIOS doesn't support USB Boot?

I'm a linux user and I used USB Flash Drive to install every linux distro to my EEEPC using UNetBootIn.

It's always working without problem, please check again your BIOS setting as said by devils casper.

Btw, please plug your USB Flash Driver to computer before you entered BIOS, is it working?

I never said the BIOS doesn't support USB boot...the computer was obviously able to (at one point) boot from USB, otherwise I would have never been able to get Ubuntu on it in the first place. The USB has always been plugged in before booting, whether booting to the BIOS or otherwise, during this process of trying to get it back working. I appreciate your effort.

I've also tried multiple UNetBootin USB drives, and multiple discs.
