There's no "magical hidden" XP lurking under Windows 7. You could install both operating systems on the same computer and dual-boot, or alternatively (and much less complicated) just get a hypervisor program like Oracle's VirtualBox or Microsoft's own VirtualPC (both of these are free, though you'll have to have a legitimate copy of XP to install) and install XP on the virtual machine.
I use windows 7 ultimate and i use *windows xp mode* which you can download if windows 7 is genuine
You can dual boot anything; as long as they are on different hard drive partitions.
Dual boot
Yes.
You will need at least two partitions.
Yes.
You have to edit the boot.ini file.
You could use Boot Camp to make a dual-boot for Windows XP, Vista or 7 and Mac OS X. You can then install Insanequarium in Windows
Yes, this would work. Yes. XP has to be installed first though because Vista does not allow the dual boot with older operating systems being installed after Vista Bob!!!!!!!!!!!!!!
Install both hard drives, decide which one is designed for xp and which for vista. Boot from xp cd and choose the hard disk you want to install to. After installation of xp finished insert the disk with vista. Run setup.exe, when it asks you about location for future system choose another drive. And follow instructions. Once installation has been completed you will have dual boot.
Install first an older system such Win98 (95, Me) and so on, and then install Windows Xp. Xp creates automatically dual boot menu.Do not install more than one OS per partition.
Yes. There is a process called Dual Booting, but it requires two hard drives. Just search for "how to dual boot windows vista and windows XP?".
