Redhat dual boot problem

[Rajesh <rajeshb frontline com au>]

Hi All,

I am trying to install Windows 2003 and Red Hat Linux Enterprise server on a
Sun Fire V20z machine (AMD Opteron processor). 

First I've installed Windows 2003. I've partitioned the 36GB hard disk. I've
allocated 12GB for windows 2003. Later I've installed Red Hat Linux on the 
2nd partition.

After I've installed Red Hat Linux I can't boot Windows 2003. I can only
boot Red Hat Linux. If I select Windows 2003 to boot it just hangs. I've
tried both GRUB and LILO but no luck.

Any help would be really appreciated.

Thanks,
Rajesh.
