grub error 16???

[llawwehttam]

I was using my Ubuntu machine fine yesterday but today I boot up and grub behaves as normal but when it attempts to boot from my os it said

"Error selected cylinder range is beyond BIOS supported range"

I havn't changed anything

 

I rebooted and this time all i get is GRUB ERROR 16

 

any help appreciated

(i suspect HDD failure)
