Thread: Windows XP 64BIt Systems stops proceeding at acpitabl.dat

Experts advice needed my Windows XP 64BIt Systems stops proceeding at acpitabl.dat

Here is brief what exactly happened to get clear idea, I have dual boot system Windows XP64 bit & Windows 7 64bit. For some reason i have connected another sata drive unplugging connections of dvd-rw drive. It runs smoothly without any problem.but after that when i reconnected my system as it is...the problem start with windows XP, while booting it stops at acpitabl.dat didn't go further...I can login in to Windows 7 without any problem only i am not able to use Windows XP. Both systems are installed
on different drives WinXp on Disk(0)Partition(1) Windows7 on Disk(0)Partition(1).

I didn't get any solution from last 2 days,so please anyone experts here.

It is a Hard Drive error the system can't find the boot drive.In my friends case he had to re-install windows..

P.S. In case of a stalled screen like I saw once you may wait 10 mins (by not doing a thing) it may auto reboot.(Not in XP 64 bit but in Server 2003,May or may not work in ur case).
