Windows 8 installed, but my pc thinks it's Windows XP

So I have 2 HDDs. On one there is 2 partitions (Windows 8 OS and storage). On the other there was no partitions. So I decided to install Windows XP on the second HDD and dual boot it, but after Installation, there is this strange error http://www.appassure.com/support/wp-content/uploads/2012/09/Boot-Error.png . What I discovered, that after I unpluged the Windows XP HDD and tryed to start Windows 8 advanced boot, it said to me that I have Windows XP installed. Strange? It gets better... When I plug my external HDD with Windows 8 install and I try to boot it up, it boots up INSTALLED Windows 8 OS, not the setup.

Any bright ideas???

When you installed xp was the primary hdd with win 8connected ?

check the assigned boot drive in the BIOS.
