Ok, so i have windows 7 as my main operating system on my 250hd, i put in an empty 500hd for a second drive and boot the compuer with with a windows xp media cd in.....i install windows media on the 500hd...starts up fine. But!, now i cant get it to start up windows 7 even if i take out the 500hd and tell the bios to use the 250hd as the first boot priority....it just tries loading xp media...and with the 250hd in it says something like insert proper boot. It will not even load up xp if i just have the 500hd and not the 250hd......and the 250hd doesnt even have the xp os on it......how do i get it to load windows 7 again.....?????
