Hi all - please help!
I have RH8 dual booting with XP, or at least it has been for some time until my first hard disk failed, which was the XP drive (i have a second 20gig drive with Linux). I reinstalled XP on the replaced hard disk, and rerun grub-install off my Linux boot CD's to get grub back. So now RH boots wonderfully (of course!) but when i select the Windows option in Grub, it just returns me to the selection screen. How can i resolve this (preferably without having to reinstall RH!)

My config is as follows:
HD1 Primary master = 20gig /dev/hda1 VFAT
HD2 Primary slave = 20gig /dev/hdb
1 0.031 99.914 primary ext3 boot
2 99.914 18581.062 primary ext3
3 18581.062 19092.937 primary linux-swap

my grub.conf looks like this (i added the 'map' commands); i have not included the top parts of the conf file to save space.

title Red Hat Linux (2.4.18-14)
root (hd1,0)
kernel /vmlinuz-2.4.18-14 ro root=LABEL=/ hdc=ide-scsi
initrd /initrd-2.4.18-14.img
title MS Windows XP Home
map (hd0,0) (hd0,0)
rootnoverify (hd0,0)
chainloader +1

I know most of you will tell me to forget XP, and i would wholeheartedly agree with you save for my wife and the fact that MYOB doesnt work under wine

Thankx

edit your /boot/grub/menu.lst:

add this after your redhat entry:

donno if this helps but hey, thats my line that boots up

dOH! That didnt work
I have a feeling its because XP had its entry in the MBR, and when i loaded Grub it wiped that out. Can anyone else help? Grub-gurus!

I would suggest something like this:

title windows
rootnoverify (hd0,0)
chainloader +1

Hey... I'm a newbie... so don't expect much from me. I have Win XP and SuSE 8.1 in my machine with GRUB. I have just 1 hard drive. My grub.conf looks like this:

root (hd0,2)
install --stage2=/boot/grub/stage2 /boot/grub/stage1 d (hd0) /boot/grub/stage2 0x8000 (hd0,2)/boot/grub/menu.lst
quit

I do not know how to edit my /boot/grub/menu.lst so I cannot tell you what it contains... if you're interested tell me how to edited and I be more than welcome to share that with you.

Good luck!

Ed.

you're almost there !

the key is really the map command but mapping hd0 to hd0 doesn't do anything. Try something similar to

title Windows
map (hd0) (hd1)
map (hd1) (hd0)
chainloader (hd1,0)+1

(grub isn't fool by the map command, just the resident OS of hd1 so hd1 still the drive from which you want to chainload)

Windows is way to capricious and U]don't[/U] want to know how to boot from a non-first hdd.
You could also pass the mapping by changing your boot sequence but it's kinda useless when you have grub

see the command section of the grub manual, it almost says the same thing as I.

sorry, my bad, i didn't see windows was on hd0...

this configuration would work if you
1. Installed windows on hd0
2. Later wanted linux, swap the windows drive to secondary (hd1)
and 3. Installed linux on a new hd0

(hey! it looks like what I once did =)

it seems like when you reran grub-install, you overwrited the mbr of windows which is needed to boot it.

Sorry if I misguided you

Did you try putting in your cdrom with windows and choosing the restore function you might have to reinstall redhat though not sure. And also i was running windows 2000 pro and i had to get a driver offline to help it reconize the linux ext2 partitions im not sure if xp is the same but my windows partition would not boot without it.

Hey all... thanks for your help so much! Problem is solved, though not from want of trying!

Well it seems that first hdd was faulty, and that was why i had trouble booting. I ended up just shoving a new hdd in and reloading XP and RH. Not something i wanted to do but it fixed the problem anyway. Which brings me to my next whinge... Windows product activation. Because i have activated more than 3 times, every time i need to reload windows (which we all know will be many) i have to ring up, punch the stoopid code down the touch tone fone, then hold, explain to an operator at M$ exactly WHY i needed to reload and then tell them the code again! GRRRR! Talk about denial of privacy and liberties.

I have vowed it to be the last time i EVER purchase or reinstall M$ software again. Linux is far too good...
