Well for those of us who are new to Linux, Here is an interesting tip. If you have Linux or any other Os on your PC, or Currently have XP or another flavor of Wendos; beware upgrading to Vista will remove the Bootloader from the MBR. Translation: It will appear that your Linux distro has been deleted.Never fear nerdlings, your distro has not been destroyed. Its just that when Wendows goes through it's installation process it intentionally ignores anything written on the MBR and rewrites a wendows only boot script/whatever. ( In my case it would delete Grub and only alow me to boot into wendows.) To fix this just pop in your favorite distro's livecd and replace your Bootloader using the terminal. And Voila! presto changeo things are back to Normal again.
