Windows XP Tablet Edition overwrites GRUB install

[William Rose]

Hi,

This is not a bug in GRUB, but causes problems: I discovered that
Windows XP on my Tablet PC modifies the MBR after booting and will
overwrite an alternative boot loader in the MBR.  I think this 'feature'
is to allow a fully graphical boot (no text, ever).  I have worked
around it by using the NT loader to chainload GRUB, but I'm interested
to know if anyone knows how to prevent this rather obnoxious behaviour
on the part of WinXP.

cheers,
Will
