It's still a beta and there are bugs, so there is a chance something could go wrong with certain system configurations. With that said, there are plenty of people who have been dual-booting since Beta 1 (5112) with no problems. In fact, once I get my extra HDD, I'm planning to dual-boot 5308 with XP x64 on my desktop.
Make an image of your existing drive/partition using something like TrueImage or Ghost. That way, even in the worst case scenario, if you end up losing all your data (highly unlikely), you can just restore the image in less than 20 minutes, and you're good to go.
You don't really need much of a howto. Basically, you need an empty extra partition (or separate hard disk) where you can install Vista. Make sure you install Vista after XP is installed. During setup, you get to pick where you want to install Vista. Select the empty drive/partition. Once setup is done, Vista automatically adds itself as well as XP to the bootloader, so you'll get a menu each time you start your machine, asking you which OS you want to boot into.
yeah..... not a single problem with dual-booting. if something goes wrong with Vista, then XP SHOULD still be in perfect working order (unless said thing that goes wrong is with the boot loader). don't be an idiot like i was, and reinstall XP AFTER installing Vista...... basically makes your Vista partition a nice little (insert number here)GB Windows Folder that you can't boot to.
as for how to install it in a dual-boot config..... just install it as you would install XP, cept choose to install it to the partition that XP is NOT on.
Yes, you delete the Vista partition, boot from your XP CD into the recovery console and run fixboot. That restores the XP bootloader, so you won't get the OS selection menu anymore at startup, and it'll boot right into XP like it normally does in a single-boot setup.

Ep, glad to see you come back and tidy up...did want to ask a one day favor, I want to enhance my resume , was hoping you could make me administrator for a day, if so, take me right off since I won't be here to do anything, and don't know the slightest about the board, but it would be nice putting "served administrator osnn", if can do, THANKS
