Can you tell us if you need to keep Windows 7?
I ask because installing XP does damage the boot manager and since you don't have the full Windows 7 DVD you can't fix that the normal way.
Also tell why you can't run XP in Virtual Box.
I have spent about five hours reading threads about people in similiar situations, but to no avail. I have created a partition (B:\) on my hard disk and simply want to install Windows XP Home Edition from a genuine Windows XP installation CD I purchased. I'm running Windows 7 Home Premium on a Compaq Presario CQ60 laptop and believe there must be a way to have both OS's on my PC, just as others have done, without removing Windows 7.
I boot from the CD by pressing the DEL key repeatedly at Win 7 startup and continue pressing it after I hear a beep when it says to press any key to boot from CD. I am given no options. It just says "Windows Setup" at the top of the screen and at the bottom indicates it is "Loading" (i.e. installing) various files from the CD, as I hear the CD running.
Then it gets to the point where it says "Setup is starting Windows" at the bottom of the screen (where it gave the status of the files being loaded). At this point, it launches a new screen which indicates "A problem has been detected and Windows has been shut down to prevent damage to your computer...Technical information: *** STOP: 0x0000007B..."
How can I get this CD (that is, Windows XP) installed on the B:\ drive? I tried running the setup program e:\i386\winnt32.exe (which is on the CD) from a "b:\" command prompt, but I get the same error as if I try to install the CD after Windows 7 has loaded: "Setup cannot continue because the version of Windows on your computer is newer than the version on the CD."
