I am trying to move a 32-bit Windows XP Home system from an Intel D875PBZ motherboard (Pentium 4, PATA HDD) to a Gigabyte GA-78LMT-USB3 (AMD, 64-bit, quad core, PATA HDD) without losing any programs/settings. I proved that 32-bit XP can be installed on the newer computer by doing a fresh installation (XP SP2 CD-ROM, no extra drivers). Now I want move the old system over, but it crashes during booting, even when choosing Safe Mode.
Originally, I got BSODs early in the boot process, but after using RegEditPE to copy over the System branch from the fresh installation's registry, it now gets to where the loading animation disappears, a mouse pointer is displayed (it looks a little large though, as though it's using a low graphics resolution), shows a green-blue screen and then reboots itself, seemingly right before the "Loading personal settings..." pop-up box, which is right before the desktop would show.
I looked at a loaded-driver log, but everything looks okay there. And I read up on the XP boot process, but the descriptions were a little vague. How can I discover (log) what is happening at this point?
