I can't guarantee its reliability. You shouldn't keep important data on the partition containing /boot if you try this, and should be prepared to repair that filesystem. (Ideally, /boot will be a separate filesystem that you can auto-backup somewhere safe regularly). It doesn't sound as though this is an important server, anyway... Suitably intimidated? Good! http://www.it.fht-esslingen.de/~zimmerma/software/ltools/ltools.html allows you to write to Linux partitions under Windows. I'd recommend having two grub configuration files, and make /boot/grub/menu.lst a symlink to whichever one of them you want to boot next. Under either OS, you would just change the symlink to the "right" configuration file and reboot. You should be able to script this... Yes, Grub can follow symlinks. I have a collection of grub splash screens, and symlink /boot/grub/picture.xpm to a random one each boot. Next boot, I see a new splash screen.
