I have Windows2000 on a seperate disk, so I don't think the grub.conf should be too different for XP... Try this:

root (hd1,0)
chainloader+1
filesystem type unknown partition type 0x7
error 27 unrecognized command

I haven't messed aroud with booting NT/W2K/XP in ages, but I have a theory for you. I have dual booted a machine in the old days with Win98 on hda1 and NT4 on hda2. I may be wrong here, but these memories are a few years old.

Good news is I don't think your problem is grub.

I think NT/2K/XP wants its boot loader on what it thinks should always be c:\, your hda1 Actually M$ classified these as boot partition and system partition, although usually on the same partition. Now pay attention, this is totally stupid, but thats M$ for you. The BOOT partition is where the SYSTEM files are, c:\winnt (NT & 2K) or c:\windows (XP). The SYSTEM partition is where the boot files are, the hardware specific files used in the initial boot. I am not making this crap up. The BOOT partition can be anywhere, but the SYSTEM partition is usually on the first partition of the first hard drive, c: to windows. The system partition has to be on an active partition. About the only thing the generally needs to be in the SYSTEM partition is ntldr, boot.ini (text file tells ntldr where BOOT partition is), ntdetect.com,

2 possible fixes.
1. Make hdb1 an active partition and hope Grub can kickstart ntldr.
2. Move your partitions around and give windows a little space in hda1. But if your gentoo install is there you have bigger problems

I once set up a box with Win98 (for games), Win2kPro(for the office), Win2K Server(for generall hacking), and RedHat linux (for fun) on one big hard drive. My rule of thumb is alway put the most fussy OS first. This used to be 95/98/Me, then NT/2K/XP, then Linux.

Good luck

gentoo is on hda

Yeah, you would hose Gentoo if you slide it down to hda2. But it is damn hard to boot a Windows OS if you can't give it the first partition on the IDE0-master channel. I guess that's how you build an OS when you assume yours is the only one in the world.

Another solution might be to get one of those physical switches that change the master/slave settings, but that cost money and is kind of kludgy.

Hi someguy,

Try this trick for dual-booting from Darth_Daver. I have Win XP on a second disk and this woks perfectly.

Good luck.

Thanks jasonm.

I really needed to know that, I had no idea GRUB could do that kind of trickery. Will file that away in tips to remember.
