Dual boot FC2T2 and WinXP?

[Markku Kolkka]

I just noticed that after installing Fedora Core 2 test 2 I can't 
boot into Windows XP anymore. The installer detected the Windows 
partition, and grub.conf contains the correct entry. This worked 
correctly in FC1 and FC2test1, what could be the problem? The 
installer complained about partition alignment, is that related?

Works for me. I have grub on the boot sector of my Linux disk, and use 
the XP bootloader on the primary disk. So I pick Linux from the the XP 
boot menu, which takes me to the grub menu.... Are you doing it that 
way or using grub as your main loader?

Though maybe not booting into Windows could be considered a feature? ;-)

Yes. The Windows XP CD rescue should recover Windows XP. 

The workaround I've found so far is to partition with fdisk (either on
screen2 on Linux installer or other-os) leaving the linux partitions marked
but empty. Fdisk is fine, but it seems the diskdruid/parted stuff corrupts
partition tables in some cases (where the geometry and the one it expects
differ).

I tried the "repair existing installation" option from WinXP 
install CD, but that had no effect.

I can't talk for WinXP but in Win2k and Win2003 you can also go into a
console mode for repair. You can repair the loader and if you have to
you can repair the MBR. If you repair the MBR, you will lose the ability
to use grub to boot linux. I have had luck before just restoring the
boot loader.

In the console mode for XP, you can use the fixmbr and fixboot command to
get xp running again.  But like Shmuel said, you will lose your grub and
will have to restore the boot loader.

I had this happen when installing Core 2 Test 1
FIXBOOT did nothing to help.
FIXMBR made my bios reject the drive as bootable.

The situation inspired me to write this:

It's not a fix for the problem - but it's how to avoid it in the future.

You might temporarily get rid of grub from the MBR. Not sure what the XP
equivalent of "fdisk /mbr" and "sys c:" are.

Also the Mandrake bug report Feliciano refers to mentions changes in the
BIOS made by the installer. Might also be the case here, so check your
BIOS settings as well.

If your partition table got corrupted you're farther from home...

Mandrake faced with some thing similar with Linux 2.6 :

Perhaps also related to ( Installation CD doesn't boot ) :

Yes, this is the same bug. The suggested fix under Mandrake is:
Fixing partition table:
  with diskdrake from drakxtools-10-24mdk do
    % diskdrake --change-geometry=hda=255,63

How do I do the same in FC2T2?
