I understood the process of reinstalling the hal.dll file through recovery console. But the problem now is the xp installation CD is not read. I can't enter the recovery console at all. I made the boot device priority to the CD/DVD ROM from the BIOS. I restarted the computer. The screen displays: Press any key to boot from the CD. I pressed a key but there is no progress in the process. No setup initializes and the system stucks to that point. What may be the problem?
