Can't boot Xp with GRUB2

**isom** · 12-29-2010

Here's the specs: XP is on sda1, Ubuntu 10.10 is on sdb1. I have tried all sorts of configurations in grub.cfg, mainly using the custom entry files and update grub, and have tried installing grub2 to each drive. No matter what I try I am getting the ntoskrnl.exe missing or corrupt error. With grub2 installed on sdb I can set BIOS to boot from sda and get into XP, but no matter where grub2 is installed I can't get into XP from there.

Default grub.cfg:

In all cases I can boot to Ubuntu. Any ideas?

**WhoIsThere** · 12-29-2010

Try a different boot loader?

Backup your MBR with something like Ptedit from a boot disc/disk, or a Linux capable program.

Then use something like Grub4Dos. It supports the syntax from legacy Grub, but also has the equivalents of options supported by Grub2.

For instance, the single XP entry equivalent in the menu.lst would like similar to this:

Code:

title "Microsoft Windows XP Professional (on /dev/sda1)"
root (hd0,0)
makeactive
chainloader +1

Or... to play it safely if the only Windows you have installed is XP:

Code:

title "Microsoft Windows XP Professional (on /dev/sda1)"
find --set-root /ntldr
makeactive
chainloader /ntldr

I'm back to the ntoskrnl.exe error again.

**isom** · 01-01-2011

...bump...

**Lostfarmer** · 01-01-2011

I do not see any thing that jumps out as bad.

I can set BIOS to boot from sda and get into XP

That still is the case ? With the linux hdd connected ?

I have read , but do not remember were, some versions of grub 2 had problems booting into XP with:

search --no-floppy --fs-uuid --set 984c09bb4c0994e2

May try when you get the grub MENU pressing 'Esc' and get into the 'edit mode' for XP and remove above line and see what happens.

**isom** · 01-02-2011

That still is the case ? With the linux hdd connected ?

Yes.

May try when you get the grub MENU pressing 'Esc' and get into the 'edit mode' for XP and remove above line and see what happens.

I tried that, still no luck. When I went back to grub-pc I put it on the XP drive, sda. I have been trying different entries for the chainloader section (chainloader (hd0)+1, chainloader (hd0,msdos1)+1, and some other random thoughts) but nothing works so far. One thing that interested me was when I tried "chainloader (hd0)/Windows/System32/<tab>" from grub command line, ntoskrnl.exe wasn't there, but it seemed like all the other files were. Surely this is something simple. I've used Linux with grub legacy off and on for years and never had any major issues.

**Lostfarmer** · 01-02-2011

chainloader (hd0)+1

If I use that command , it will just reload my MBR boot code. For me the 'chainloader (hd0)' command over ruled 'set root=(hd0,1) command at where to look.

chainloader (hd0)/Windows/System32/<tab>

that retured no such partition, being (hd0) is the mbr, did not matter what I had 'set root=(hdx,x)' at.

Below may/may not be the problem, due to fact XP will boot with the linux hdd connected. But its the only thing I can see that not quite right.

Your hdd does not met the MS standard partition layout on the logical volume. The logical volume should start 1 track '64 sectors' after its 'extended partition table' and your's start 2 sectors later. XP can not read linux file system but it must account for all partitions. {remember 64 sectors is sector 0--63}

Boot Info Script:

Code:

Partition  Boot         Start
/dev/sdb2         149,858,302   
/dev/sdb5         149,858,304

***,304-**,302=2

Unknown BootLoader on sdb2 IE: the extended partition table. The first 01be of data is useless in your case, due to grub is not installed on the extended partition.

Code:

00 fe  |.....SV.u.......|
000001c0  ff ff 82 fe ff ff 02 00  00 00 00 78 62 00

the item above in bold is the start sector of the logical volume ,after it's partition table and is in little endian format.

I would delete the swap partition and use a GUI partition editor to remake or if you want to use fdisk , the extended volume shoud start at sector 149,858,302+64=149,858,366

I changed some things with gparted, still getting the ntoskrnl error. Here's the new bootinfoscript.

Code:

Grub 2 is installed in the MBR of /dev/sdb and looks on the same drive in 
    partition #1 for (,msdos1)/boot/grub.

If you look at the menu intries for linux they are set for (hd1), I do not understand why ? I've only seen the hdd where grub is installed becomes (hd0) not (hd1), could that be causeing a problem for XP ?

Code:

menuentry "Microsoft Windows XP Professional (on /dev/sda1)" {
    insmod part_msdos
    insmod ntfs
    set root='(hd0,msdos1)'
    search --no-floppy --fs-uuid --set 984c09bb4c0994e2
    drivemap -s (hd0) ${root}
    chainloader +1
}

It says XP is on /dev/sda1 but "set root='(hd0 ' why ?try changeing both (hd0) to (hd1). Yes, I am in a guessing game. I do use a older version of grub2 so can not check it out.

On my comp with grub on (hd0,1) and XP on (hd1,5)

Code:

menuentry "Win XP  (on /dev/hdc5)" {
    set root=(hd1,5)
    chainloader +1
        drivemap (hd1) (hd0)
        boot
}

Could enter correct info (hd1,1) at grub command line and try my menu.

When booted into XP check 'boot.ini' to be sure nothing is amiss that the bootinfo script is not showing. A net search give 3 reasons normall for your error, boot.ini,hal.dll,ntoskrnl.exe is bad or ?.

added:
more thinking. Check /boot/grub/device.map , if linux hdd is not (hd0) change it so it is and rerun update-grub "I think that's the command'. I could be way off in my thinking, so any problems it may make is your's.
