first of all, il explain what exactly i wanted to do with my laptop which is currently running a Vista Home Premium 32bit. I needed to install an 64bit ver of XP Pro on a 2nd partition and set it to dual boot. My laptop is a Fujitsu-Siemens and has a single WD 250GB Sata HD and my processor supports 64Bit OS. I followed the instructions on the forums on how to shrink a partition and create a new one for the second OS(XP). However, after going through the procedure i placed the XP disk in the tray and booted from it. It was loading just fine then suddenly after i press enter when i was asked to continue to install, it mentioned later that it could not detect any hard drive or that i need to disable any program or whatever. I figured maybe theres a setting in the bios but i found nothing i can do with the HD settings.
Im not familiar with Vista so i need to know is there any possiblility to install the XP OS. IF yes then id appreciate if somone can explain to me how.
Also, i was wondering if the manufacturer locked the HD and maybe the only way is to reformat the HD and reinstall everything.
