Ok, I had Windows and Mandrake 9.2 RC2 installed on two partitions, when I used the empty third partition to install Red Hat Severn, which changed my GRUB loader, and now I can't boot into Mandrake.

Is there an image to download to create a boot floppy (I don't have one)?

Thanks!

What medium have you installed Mandrake from? If that's CDROM, you can use it as rescue disk. But I don't think you need it.
Does RedHat boot OK? If it does, you can fix GRUB configuration (what means: add Mandrake).
Please boot to RedHat and post its /etc/grub.conf. Please also write which partition is Mandrake installed to.

In earlier versions of Redhat, the file was /boot/grub/grub.conf; I don't know if that's changed though.

Yes, I can boot into Red Hat.

My grub.conf file is:

#boot=/dev/hdc
default=2
timeout=10
splashimage=(hd0,5)/boot/grub/splash.xpm.gz
title Fedora Core (2.4.22-1.2097.nptl)
root (hd0,5)
kernel /boot/vmlinuz-2.4.22-1.2097.nptl ro root=LABEL=/ hda=ide-scsi
initrd /boot/initrd-2.4.22-1.2097.nptl.img
title Fedora Core (2.4.22-1.2088.nptl)
root (hd0,5)
kernel /boot/vmlinuz-2.4.22-1.2088.nptl ro root=LABEL=/ hda=ide-scsi
initrd /boot/initrd-2.4.22-1.2088.nptl.img
title Windows XP
rootnoverify (hd0,0)
chainloader +1
title Mandrake Linux
rootnoverify (hd0,4)
chainloader +1

I have three partitions: Windows NTFS (hdc1). Mandrake 9.2 RC2 ReiserFS (hdc5), and Red Hat Severn ext3 (hdc6). I have two kernals installed for Red Hat. For the Mandrake entry, I think hd0,4 is correct, but I don't know the kernal and initrd enties. I can't look up those files to see what they are either, because Red Hat and Win doesn't have ReiserFS support.

Thanks again for any help!

My Redhat/Mandrake/Windows system is at home right now, and I'm not. Unless someone posts the correct Grub entry before me, I'll post it when I get home.

Ok, great! Thanks!

In the mean time can you verify something? Your current config file indicates that Mandrake is installed on the 5th partition (first logical partition) of hda1; is that correct?

I don't know. I'm not quite sure what you mean by hda1 or first logical drive. Hopefully this can help. I have one 100GB HD with 3 partitions. Hawdware Browser in Red Hat displays the following (">" are for the indentions):

/dev/hdc
>hdc1 ntfs (WinXP)
>hdc2 Extended (not quite sure what this is, but it looks like hdc5 and hdc6 are under it)
>>hdc5 reiserfs (Mandrake)
>>hdc6 ext3 (Red Hat)

Sorry- still stuck away from home (working a Win 2k system). After I get done here I'll need sleep, so I'll follow tomorrow.
