I have 3 hard disks of 2 TB each with plenty of space for partitions. I run a multi-boot manager with a number of Windows OSs including Windows Vista and Windows 7, along with a number of Linux distros. I would like to install Windows 8 in its own partition, not upgrade Windows 7. I am willing to pay the extra money to by Windows 8 Pro. I have a number of questions about installing Windows 8: 1) Can Windows 8 be installed on any of my 3 hard drives, as opposed to just the first hard drive ? 2) Can Windows 8 be installed on a non-primary MBR partition ? 3) Can Windows 8 be installed on a GPT partition ? 4) Will a Windows 8 clean install wipe out the rest of the hard disk on which I install it ( I have heard rumors of this ) ? I am trying to make the installation of Windows 8 as painless as possible without affecting the other OSs I already have installed and without Windows 8 interacting with any of the other OSs in any way. I can unplug two of my hard drives as necessary, clear out my third hard drive, install Windows 8 on that third hard drive, and then plug in my other two hard drives if necessary and attempt to multi-boot into Windows 8, but i am hoping this will not be necessary.
