I replaced a harddrive on an emachine, and installed Windows XP PRO. This was an unattended install. Windows assigned the new drive letter as H. The customer uses softeware that requires system files to be on the default C drive. I followed a proceedure suggested on the forum to swap the drive letters *(using the rename dos device in regedit), renaming master drive to C and a removeable flash drive to H. Now I am unable to boot beyond the windows logo screen. What steps will I need to take to be able to boot into windows?
