Start your machine and after BIOS screen, keep SHIFT key pressed. GRUB menu should be there. If you can see the appropriate entry to boot, try it. It may work. If there’s only memtest entry or other entries,press c for a GRUB2 command line.There should come the GRUB shell. sh:grub> _ Following is about my partitions,ubuntu karmic was installed in /dev/sda6 and the installation disk in /dev/sda3: /dev/sda1 : Primary, VFAT. /dev/sda3 : Primary, ext3. My installation disk area (~760MB) /dev/sda2 : Extended |__ /dev/sda5 : swap. |__ /dev/sda6 : ext4.
