OPERATING SYSTEM NOT FOUND. after moving from 80gb boot drive to300gb boot drive

I have an Emachine T2682. It's about 5 years old. Intel Celeron.
Phoenix bios.

I had a tried and tested ghost image of the boot partition handy when
my 80 maxtor died a few days ago. I replaced it with a 300gb maxtor. 3
partitions - 30gb c: ntfs just like the original. 15gb fat and the
rest NTFS.

I restored the boot partition with ghost. But when I attempt to boot
from drive I get Operating System Not found.

I checked pin setttings on the new drive. When I boot to windows 2003
it sees an the OS installed on C:

I now suspect it's the Bios.

Any way around this? Maybe a Phoenix bios upgrade? I have the CD with
drivers from Maxtor and they discuss something about 48 bit
comaptibility an din the bios setup I see enable 32 bit I/O(but not
48 bit).. But how can I apply those to windows or the OS if I can't
boot the OS.

Thanks for any help or information

OS not found usually means partition is not active or bootable.
