Hi all,

I'm trying to install dualboot on my PC. I have had the XP x64 installed. After that I installed the RHEL AS 4.0. The first time it worked ok, on startup I got the GRUB selection menu which let me choose which system I want to boot into. After that because of some hardware driver issue,I reinstalled (reformatted the disk) XP x64, right now I'm reinstalling RHEL AS 4.0. But no matter what I have done, the initial GRUB selection menu just wouldn't show up. Everytime I rebooted the computer, after the initial testing and some silent moment (with blank screen), the computer just booted right into XP. I think the disk partition is about the same as my first installation when the GRUB worked fine. My installation is as follows:

On the main disk (a WD SATA Raptor), the 1st 20GB is installed with XP system (NTFS), the next 80GB is installed with RHEL (1st 50MB allocated to /boot, 2nd 9GB to swap, others to /). Another disk (WD IDE) 1st 100GB allocated to windows (NTFS), the other 150GB to RHEL /home). For the bootloader, I selected to install the GRUB bootloader, and (to my memory) boot from /dev/sda6 (which was the location where the /boot was located).

I did some research on Google, one point they say is that the the boot sector (/boot) need to be located within the 1st 1024 sector (8.4GB) of the disk. I don't know if that's the problem. But I'm pretty sure the first time when I got the GRUB selection menu successfully loaded, I didn't install the /boot into the 1st 1024 sector.

Please help me to figure this out with a little bit detail. I have some knowledge about this bootloader stuff, but only at entry level.

Thanx in advance!
