    Installing Win8 on a new disk boot issues

    Before, my PC was setup like this:
    - disk0: windows xp
    - disk1: windows 7
    Bios boot priority set to disk1.
    So no boot loaders, when I (rarely) need xp, I would switch via bios

    Now I wanted to try Win8, so I've
    - download 'Win8.1 Enterprise Evaluation' and burnt on a dvd
    - bought and connected a new disk (disk2)
    - boot from dvd, installed choosing the new disk2

    Now, everything works fine, win8 got installed on disk2.
    But the strange thing is this:
    - if, from bios, I choose disk2, it says the disk is not bootable
    - choosing disk1, a boot loader shows up, letting me choose between win7 and win8.1
    (- choosing disk0, nothing has changed, xp starts like before)

    So, I'm confused. I was expecting win8 booting from the new disk2.
    - why disk2 doesn't boot?
    - would have been better physically disconnecting disk0 and disk1 before installing?

    AFAIK, Windows 8 bootloader installs to the first disk in the boot order...thus best to change the boot priority to the disk that's being installed to, rather than physically disconnecting them.

    Ah, that makes sense.
    So to fix this I guess I can phisically connect on drive at a time and repair it booting from the proper installation dvd, and running something like
    bootrec /fixboot
    bootrec.exe /fixmbr
    (maybe tools like EasyBCD can do the same thing but I'm not sure I want to learn using it just for this)

    win8: using the repair option from the installation dvd fixed everything
    win7: the repair option didnt work, so its been easybcd to remove the win8 entry + bootrec

    thanks, bye
