ok I tried to dual boot my preinstalled windows vista x64 dv7-1020us with windows xp x64 before reading that I shoudlnt do so :(
i partitioned an area for xp pro 64bit edition and slipstreamed the intel matrix storage managerx64 and made a bootable cd.. I started my pc and booted from cd and the windows xp 64bit edition began to load the files, the installation continued and asked where I wanted to install xp and I chose the partition I made and chose yes to continue..
after copying the files from the cd the computer restarted. when it restarted there was an error "unable to load Operating system"... I powered off the pc and restarted again and booted from cd once more.. I then chose the area I made once again for the xp partition and chose to reformat to ntfs and copy files.. it reformated the partition and began to copy the files..
the computer proceeded to restart again but now it just hangs and sticks on the HP invent welcome screen..
if I try to get into the bios or boot menu or even recovery by presssing f9 f10 f11 etc nothing happens.. it just stays on that welcome screen.. I dont know what went wrong ..can someone help plz or has any ideas on what happened
