Hi all...
I have a Toshiba A210-12U lappy which has dual core AMD turion 64 processor.
It is running windows Vista.
A couple of weeks ago i installed the latest Ubuntu 10. ? LTS as a duel boot with the grub loader and it worked fine and all was well.
I could choose at bootup and both systems worked fine.
Today i rebooted my lappy and got..
error-unknown filesystem
grub rescue>
I am now running on Ubuntu via a USB pendrive.
I dont have any rescue CD for my vista as the OS was preloaded into a rescue/restart type hidden partition on my HD as from new.
I'd like to get back to my dual boot working system if poss...
What can i do ?
Thanks
Jo
EDIT
I've downloaded and run the boot info script as suggested elsewhere and the output is as follows...
