Yet another dual boot question.

Kix · 12-14-2004, 01:56 PM

I have two hard drives, primary ide master is SuSE 9.1 with GRUB as the boot loader. The other hard drive, primary ide slave with w2k (ntfs). After reading through aus9's dual boot how to I'm still confused.

How can I get grub to list the option of booting to the w2k drive?

After losing the entire xp partiition on my laptop when trying to dual boot, I've gone for the 2 disk scenario to give me a bit of cover.

Any assistance appreciated.

Cheers

Add (or just uncomment it - it's probably already there in roughly the correct format anyway) the following lines to your /boot/grub/menu.lst file:

Code:

title           Windows 2000
root            (hd1,1)
savedefault
makeactive
chainloader     +1

You may need to change the root entry depending on which partition you're using on your second IDE disk.

Thanks mjrich.

Gave your suggestion a try, my menu.lst looked like this:

# Modified by YaST2. Last modification on Fri Nov 19 17:25:30 2004

color white/blue black/light-gray
default 0
timeout 8
gfxmenu (hd0,1)/boot/message

###Don't change this comment - YaST2 identifier: Original name: linux###
title Linux
kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 vga=0x31a splash=silent desktop resume=/dev/VolGroup00/LogVol01 showopts
initrd (hd0,1)/boot/initrd

###Don't change this comment - YaST2 identifier: Original name: failsafe###
title Failsafe
kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 showopts ide=nodma apm=off acpi=off vga=normal noresume nosmp noapic maxcpus=0 3
initrd (hd0,1)/boot/initrd

So I changed it to this:

# Modified by YaST2. Last modification on Fri Nov 19 17:25:30 2004

color white/blue black/light-gray
default 0
timeout 8
gfxmenu (hd0,1)/boot/message

###Don't change this comment - YaST2 identifier: Original name: linux###

kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 vga=0x31a splash=silent desktop resume=/dev/VolGroup00/LogVol01 showopts
initrd (hd0,1)/boot/initrd

title Windows 2000
root (hd1,0) *** also tried hd1,1 ***
savedefault
makeactive
chainloader +1

###Don't change this comment - YaST2 identifier: Original name: failsafe###

kernel (hd0,1)/boot/vmlinuz root=/dev/hda2 showopts ide=nodma apm=off acpi=off vga=normal noresume nosmp noapic maxcpus=0 3
initrd (hd0,1)/boot/initrd

When I select Windows 200 in GRUB I get:

root (hd1,0)
Filesystem type unknown, partition type 0x7
savedefault
makeactive
chainloader +1

So I guessed wrong and changed the line:

root (hd1,0)

to

root=/dev/hdb1 (and hdb0 and hdb2 just in case)

Same thing happens, only I get the GRUB list back after the error.

Hmmmmmmmmm, more play needed.

Thanks

From your SuSE /etc/fstab, do you know which partition Win2k is on ?

not much in there makes much sense to me:

/dev/hda2 / reiserfs acl,user_xattr 1 1
/dev/VolGroup00/LogVol01 swap swap pri=42 0 0
/dev/hda1 swap swap pri=42 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
proc /proc proc defaults 0 0
usbfs /proc/bus/usb usbfs noauto 0 0
sysfs /sys sysfs noauto 0 0
/dev/dvdrecorder /media/dvdrecorder subfs fs=cdfss,ro,procuid,nosuid,nodev,exec,iocharset=utf8 0 0

But hdb has no mention.

So, will I need to add something here?

How inconsiderate of SuSE to not autodetect your win2k drive - someone really must have a word to Novell

Is there any sign (from your SuSE setup) of the second hard drive - whether in My Computer, /data-xyz, or elsewhere ? Anyway, it's possible that having win2k as a slave is upsetting things, so you could try adding two lines as follows:

Code:

title           Windows 2000
rootnoverify    (hd1,0)
map             (hd0,0) (hd1,0)
map             (hd1,0) (hd0,0)
savedefault
makeactive
chainloader     +1

The map lines will hopefully fool windows into thinking it's being loaded from the master drive. <sighs>. such is politics. Changing the root to rootnoverify, as above, may also help.

Cheers! Dual boot now works perfectly. However as you suspected, I still can't 'see' the windows drive as you normally can on a partitioned single disk. The only way I can find hdb is to use Partitioner from YaST.

So will I need to add a line to fstab to mount the drive on boot up?

Once again, thanks!

Great to hear

You could try adding a line to /etc/fstab, as follows

Code:

/dev/hdb1       /windows        ntfs    ro,auto,user,umask=0022       0       0

-and adding a /windows directory to your root partition. Or alternatively go through Yast to achieve the same thing. Once that's in, you should be able to add an icon to the desktop (add device/hard drive etc.) if you wish.

Cheers,

Now that's what I call service.

Thanks man.

No worries
