upon installing few essential packages and updating opensuse 11.1 when i restarted my Dell inspiron 6000 with windows vista installed there was no grub boot loader menu instead got a error message that no boot device found, insert floppy to continue.
I tried to repair GRUB boot loaded by reparing the installation using opensuse 11.1 DVD but all gone in vain, even after successfully repairing the boot loader restart shows no boot menu!
