Problem with dual boot - winXP will not boot

English Install/Boot/Login

I have a problem that I can not get winXP to boot from grub.

I replaced Vista on a laptop with WinXP, which as expected clobbered grub. After a successful WinXP install (rebooted winXP twice to confirm it boots ok) I then restored grub from the Linux DVD.

Now I can boot openSUSE-11.1 again from the grub menu selection, but winXP fails to boot, giving the error “NTLDR is missing”

The active partition is /dev/sda4.

Any suggestions on this? I’ve read of many others with a similar problem, but none with a solution. Note the winXP install is brand new. Booted twice after a fresh install with no file changes, so nothing has been done from a user perspective on the winXP side. Rather IMHO there is something pecular to the way this Service Pack 3 winXP boots that is bringing this about.

Again symptoms: openSUSE-11.1 will boot, but winXP (which is /dev/sda3) will NOT

Ok, found the solution.

WinXP went and installed its boot loader on /dev/sda2 (the 2nd partition) even though MS-Windows itself is on /dev/sda3.

So the solution is a simple edit, deleting the old “vista” entry in the menu.lst and changing the name of the “dell-recovery-partition” to “winXP” and booting to /dev/sda2 (for MS-WinXP) when then runs in /dev/sda3.

It does make /dev/sda2 next to useless, but I figure I can always restore it later if need be.

And the wife is now happy, as she has winXP as a direct boot on this laptop!

Merry Christmas to all !

Yep, you have to watch that, it always goes for the first avail primary it can use. Win7 did it to me a few weeks back, man I had a bit of a rage about it. Totally and utterly useless.

Indeed - I got “hit” by two glitches replacing Vista with XP while keeping openSUSE.

The 1st was WinXP refused to boot during the 1st reboot when installing. Turns out /dev/sda4 (the extended partition containing my openSUSE Linux partitions) was the active partition when I installed winXP, and winXP would not change the active from /dev/sda4 to /dev/sda3 and hence would not boot after installing on the hard drive. I had to change (with gparted) the active partition to /dev/sda3 myself.

Then I had the above boot problem, where winXP went and put its boot loader on /dev/sda2 instead of /dev/sda3.

One year ago, both of those problems probably would have blocked me. Fortunately I’ve learned a bit about partitions and grub the past year that eventually, after some pain and brainstorming with help and encouragement from users on IRC chat #suse, I was able to find the solution.

that’s why i say, “Install Windows first.”
