How many drives do you have in this system.
It's currently trying to boot the second HDA IDE drive, partition 4.
It appears that your boot is actually stated as /dev/sda5
5 64.5kB 198GB 198GB logical ext3 boot
I would try to change your system menu.1st to read hd0,5. ATA disks appear
as /dev/sda while actually utilized as hd0 in GRUB:
root (hd0,5)
Which is the boot partition below.
If you cannot boot that partition, verify it with fdisk; it's possible that
you have gotten a virus that corrupts your boot sector.
Boot your distro and select repair if possible.
