It's like that tutorial says. Forget about backing up grub.conf. This is nonsense. You want to make a backup before changing it, just in case, but not because of the XP installation. After the installation you have to reinstall grub with "grub-install" (from a live disk) and add the chainloader stuff to grub.conf.
mount /dev/sda2 /mnt/linux (if that is where you linux resides) grub-install --root-directory=/mnt/linux /dev/sda (if you want to install it to the partition use sda2 instead of sda, then the partition has to be active, so that you can boot from it)
Instead of using grub-install you can backup the mbr before the installation and then restore it afterwards. You can easily get bad results from that if you mistype, though.

When i install multi-boot machines, i prefer to use GAG boot manager.
It installs itself on the MBR (it's tiny) and all you have to do is tell Linux to install its boot stuff on its own partition.
As for Winblows, it always wipes the boot record and replace with its own crap. No problem, let Winblows install itself and after everything is done, just re-install GAG, configure the menu items and you're all set.

I've had nothing but good results with dual-boot *if* Windows is installed first and then add linux. The other way around is a first for me.
Thanks for your inputs, Kai and Guy!

Generally speaking, which one is the easiest and/or safest if time is an issue and you want to things fast and streamlined doing this, grub-install or backup and restore MBR. That is assuming I don't screw up when I do either and mistype or something.
Or are both things different sides of the same coin kinda' thing?

Isn't reinstalling GAG the same thing as reinstalling grub. What's the incentive so to speak? Is GAG so much better, or just easier to work with than grub?
