You have Linux already installed but want to dual boot it with Vista on the same hard drive
We'll dual-boot Ubuntu 8.04 with Vista. With Ubuntu already
installed and owning the entire drive, we'll use the Ubuntu Live CD to shrink the Linux partition to create space for the Vista install.
Vista's MBR will overwrite GRUB during installation, so we'll go through two scenarios. First - reinstall GRUB to the Linux partition and use EasyBCD to modify the Vista bootloader so that it will boot Ubuntu. Second, reinstall GRUB to the MBR and configure it boot both Ubuntu and Vista
and If you're installing the OSs to separate drives you may not have to repartition anything. However, if one of the drives carries data that you want to keep you will need to shrink the data-carrying partition (assuming it takes up the entire drive) to make room for another partition into which you would install the new OS. Otherwise the OS installation will overwrite the existing partition and you will lose all the data.
If Linux is the OS on the first drive and you install Vista on the second drive, Vista will still overwrite the Linux bootloader. So when you reinstall GRUB, you'll need to tell it where to find the Linux partition (on drive x, partition x). BTW, we're doing another step-by-step featuring dual-booting of OSs on different drives. It will be up shortly.
