I am upgrading my laptop (Gateway M405) from its 60G HDD to a WD 320G HDD. I am running XP SP2. I cloned using the automatic settings expanding the partition to the new drive's size. When I boot from the new drive (other drive is removed), I get the error on a full page of text that is there for only a second then it reboots. So, windows is trying to boot. The computer has only one drive slot, so I cloned using USB. I swapped the drives and cloned from USB with same results. BIOS recognizes the drive (obviously since it is starting windows). Same results when starting in Safe mode. Any ideas?
