I have an HP ProBook 5330m with SSD, without CD, and Windows 7. I also installed ubuntu 12.10 and have been dual booting for many months now. Something went wrong and now I can't boot my laptop at all!
The error message is
error: invalid arch independent ELF magic. grub rescue>
Another problem is that I cannot boot from USB! I tried to create usb startup disks - ubuntu live CD, supergrub, ... but when I configure the USB as first boot sequence, I get the error:
Remove disks or other media. Press any key to restart
So, I'm really stuck. Any suggestions?
How can I recover my system with the
grub rescue shell?
