I recently purchased an old Motorola ML900 with no HDD. Using an optical bay caddy I installed a used sata hdd that contained Windows 7. I then used an external dvd reader to install a copy of XP (after resetting the boot order of course) and now it only partially goes through the set up process before rebooting and returning to square1. I have deleted partitions and formatted when prompted, but because there is no (accessible) os I can not go through the repair processes I have seen for similar issues. Any help would be greatly appreciated.
