Yes, I did use quick format as FAT (not NTFS) and install XP on the exact partition. It seems to me that the system runs GRUB on MBR stored on hda, but GRUB can not find the hda1, which is XP on. Thanks for your replies.

Hi danleff, Thank you for your reply. I am using a DELL Latitude C800 notebook with two ide HDs. The primary HD had Windows 2000 and the second HD is in a modular bay and FC4 was installed. It worked perfectly. Few days ago, I upgraded the BIOS and put Windows XP (got rid of Windows 2000) on the primary HD. When the system rebooted, the GRUB menu was gone. And then I re-installed FC4 on the second HD and get back the GRUB menu. Now I can have two options - first one runs FC4 and second is to go to Windows XP (this is default). However, when the system try to XP, it just quickly display Booting 'Windows XP' rootnoverify (hd0,0) chainloader +1 GRUB Loading stage2... and returns to the GRUB meun. the device.map file contains: (fd0) /dev/fd0 (hd0) /dev/hda (hd1) /dev/hdc (I do not know why not hdb) the menu.lst (grub.config) file contains: #boot=/dev/hda default=1 timeout=5 splashimage(hd1,0)/grub/splash.xpm.gz hiddenmenu title Fedora Core (2.6.11-1.1369_FC4) root (hd1,0) kernel /vmlinuz-2.6.11-1.1369_FC4 ro root=LABEL=/ rhgb quiet initrd /initrd-2.6.11-1.1369_FC4.img title Windows XP rootnoverify (hd0,0) chainloader +1 hda is the primary drive and has XP. hdc is the second drive and has FC4. I can't see anything wrong here. The other thing could be the new BIOS version, otherwise, I do not know what is going on here. Thanks for your help.

Dear friends, I have two hard drives in my computer and installed Windows XP with FAT format on the first hard drives (hda) and installed FC4 on the second hard drives and installed GRUB on MBR of the hda. The default OS is set to XP. When the system was rebooted, the GRUB menu showed up and tried to run XP, but it did not run XP and came back to the GRUB menu. But if FC4 is picked, FC4 runs ok. What wrong is it? Thank you in advance for any help.
