is the dvd drive set as the first boot device in the BIOS? if not, set it as first, then you should be able to boot using the windows install disk.

you could try, but you will probably get a ton of errors unless the hardware is exactly the same. not to mention the activation issues.

i guess you dont have a win7 dvd?

you should be able to use the home premium x64 dvd to fix the mbr. you might have to run it 3 times in a row, before it fixes everything:
