I'm trying to dual boot 2 partitions. one with W7 already installed and I ghosted a partition of xp from an old HDD. I've assigned a drive letter to the system*what's it called* partition and copied over the 3 files, ntldr, boot.ini and ntdetect.com. when I reboot i get the 2 choices but when I choose XP it goes to a black screen and beeps once and reboots again. I checked to make sure the ntdetect.com file was in that sys. drive and even deleted and recopied it again. Is there anything someone can think of that I might be doing wrong?
