grub doesn't recognize first hard disk with windows


I installed RH 7.2 without any problems but when I rebooted grub didn't give me the option to boot windows. I tried to intitialize a chainload but that didn't work either.
I have windows ME on the first hard disk and RH on a second both are configured as master drives.
Can anybody help me set up a double boot? Right now I'm booting from a disk wich is quit slow.

This is my grub.conf

I only have one disk with 3 partitions (WIN2K,WIN98 and Linux)
Linux with 2 kernels

Maybe this give you some ideas

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd0,4)
# kernel /vmlinuz-version ro root=/dev/hda6
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd0,4)/grub/splash.xpm.gz
title Red Hat Linux (2.4.9-13)
root (hd0,4)
kernel /vmlinuz-2.4.9-13 ro root=/dev/hda6
initrd /initrd-2.4.9-13.img
title Red Hat Linux (2.4.7-10)
root (hd0,4)
kernel /vmlinuz-2.4.7-10 ro root=/dev/hda6
initrd /initrd-2.4.7-10.img
title Win2k
rootnoverify (hd0,1)
chainloader +1
title Win98
rootnoverify (hd0,2)
chainloader +1

Good luck

I'm using GRUB to dual boot Linux and NT, each on a separate drive; the grub.conf follows:
- - - - - - - - - - - - - - - - - - - -

title Red Hat Linux (2.4.9-13)
root (hd0,0)
kernel /vmlinuz-2.4.9-13 ro root=/dev/hde2 hdb=ide-scsi
initrd /initrd-2.4.9-13.img
title NT
map (hd0) (hd1)
map (hd1) (hd0)
rootnoverify (hd1,0)
makeactive
chainloader +1
- - - - - - - - - - - - - - - - - - - -

The only thing I can think of that may be missing from your file is the makeactive line. (I need the two "map" lines because windoze is not on the first drive in my configuration.)

I tried those lines on the command line but the system froze. Later I installed linux again but without a bootloader, leaving only the textual interface of grub and then it did work. I will try to make the change in the configuration file though, perhaps then it will work. Thanks

boot into linux, goto \boot\grub
edit grub.conf

you might see something like this:

rootnoverify
makeactive
chainloader +1

You might need just the "title"
so that it will be displayed...

If that doesn't work and your reinstalling...
When installing and your setting up the linux boot type, at the bottom of the screen linux partition is labeled with a title "redhat 7.2"...but windows partitions isn't, you have to hightlight it and type a name, and thats probably why there wasn't a prompt for windows after the install.

hope that helps...good luck

oops

I think I found the problem. It doesn't show the windows disk there at all (I have to HDD), it doesn't recognize it!
That does seem strange to me though since it does install Grub in the MBR of that windows (C) disk.

Help?

Well, basically you need to change the partition id from 'Windows Extended' to 'Windows 95 Extended' that way Windows thinks it's well ... another windows partition. It will work. Have faith.
