GRUB dual booting

Skyone · 03-13-2006, 03:16 AM

I've seen this problem around, but I have no clue how people come to solutions with the given variables.

I need to make my GRUB loader boot Linux (and Failsafe, etc.) and also boot my XP.

Linux SUSE 10.0 is on my only IDE HDD.

Windows XP Pro is on my only SATA 3gb/s 250gb HDD.

When I enter fdisk -l in a terminal, I get:

Code:

linux:~ #  fdisk -l

Disk /dev/hdc: 60.0 GB, 60022480896 bytes
255 heads, 63 sectors/track, 7297 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hdc1               1         131     1052226   82  Linux swap / Solaris
/dev/hdc2   *         132        7297    57560895   83  Linux

Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1   *           1       30401   244196001    7  HPFS/NTFS

In my menu.lst in /root/boot/grub, there is this:

Code:

color white/blue black/light-gray

    initrd /boot/initrd

How can I change my menu.lst/GRUB to boot Windows XP correctly?

Currently, GRUB only sucsessfully boots Linux and Failsafe, but when I boot Windows, it just resets GRUB.

Help?

Ah jeez, I hope there's a loose bumping policy...

Please, I can't get to my XP!

if XP is on your SATA Drive shouldn't your grub entry for XP Be

title Windows
chainloader (sd1)+1

or something similar to point it to the SATA Drive not the IDE One?

Skyone · 03-13-2006, 03:42 PM

I suppose so, I'll try it out.

Sorry, I'm new(er) to linux, so I have no clue what to put in.

Thanks.

i do a lot of trial and error in linux myself. if you open up the partitioner it should show you what that drive is called whether it's sda or sd1 or whatever. then just point it to the right partition in grub. typically written (sd1,0) sd1 being the sata drive and 0 being partition 1 of that drive. or whatever

When I boot into windows now (after replacing chainloader (hd1)+1 with chainloader (sd1)+1), I get this error:

Error 23: Error while parsing number

In the partition manager, it says XP is on /dev/sda1/.

That's all I know.

truoc444 · 03-13-2006, 04:05 PM

try sda instead of sd1 i dont' have SATA Drives so i can't know for sure, but i know it's somethign like that.

Skyone · 03-13-2006, 04:08 PM

Ok;

So it should be:

Code:

# Modified by YaST2. Last modification on Wed Sep 14 22:15:14 UTC 2005

color white/blue black/light-gray
default 0
timeout 10
gfxmenu (hd0,1)/boot/message

    initrd /boot/initrd

    initrd /boot/initrd

That's what it should be now?

truoc444 · 03-13-2006, 04:10 PM

as far as i can tell yes. anyone else have any ideas?

Skyone · 03-13-2006, 04:14 PM

Alright, I tried that out, it gives me the same error.

Any other ideas?

truoc444 · 03-13-2006, 04:18 PM

what about chainloader (sda,0)+1

Skyone · 03-13-2006, 04:43 PM

Nope, truoc, I still have the same exact error...

truoc444 · 03-13-2006, 04:49 PM

sorry i'm out of ideas. maybe i'll have to go out and get a SATA Drive sometime so i can start playing with them. i'll keep googling if i come across anything else i'l llet you know.

truoc444 · 03-13-2006, 04:55 PM

i just found this:

Okay looking at the Grub config file you posted it seems that it's thinking Windows is where it is not. That is it's looking at your ide drive not your sda drive.

For the windows stanza try this:
Code:

###Don't change this comment - YaST2 identifier: Original name: windows### title Windows XP Media
rootnoverify (hd1,0)
chainloader +1

And in your /boot/grub/device.map put this line (if it isn't there already)
Code:

(hd1) /dev/sda

or try this:

title Windows XP Media
root (hd1,0)
savedefault
makeactive
chainloader +1

brian_lad · 03-13-2006, 04:59 PM

how about chainloader (sda1,0)+1
