from windows 7 to xp and now cant install xp on hdd??? please help me?

Hi there, i have a fujitsu siemens p1 1505. it was working fine with windows 7 but the lady has an program that doesn't work with windows 7. So i tried to install windows xp. didn't work got a message saying no hdd's detected. so i removed the hdd and connect it to a pc and succefully installed windows xp. insert it back in the laptop and when it boots it gives me a flickering "_" please tell me what to do.

Some said it can be the SATA RIAD.....but i cant disable it on the bios.....

Thanks i know i can rely on you guys advising me on this one....please help me solve this problem

Yes sir i did it was Bernina embroidery software editort lite v4....

After i tried that compatibility mode i got the blue screen the whole time even when i tried to repair, safe mode ect.....

Does the software require huge amounts of resources? If yes you might want to reinstall as it could be corrupted somewhere since 7 has a massive list of compatability db. If no and reinstall doesn't work may I suggest using an alternative like a virtual computer @ emulators.

i cant get an OS installed on this latop now dont know why

Be sure to do a clean installation with oem discs.
