Windows "likes" to set the the drive ID letters like this:
Now when you sysprep telling it to move the Users to a specific drive, after the reboot Windows might find that intended target drive for Users folder has another drive ID letter and your intended drive D: is now E:. Sysprep fails and you have to reinstall.
- Drive C: > The system drive where Windows will be installed
- Drive D: > First optical drive (CD / DVD drive)
- Drive E: > Second partition on the same disk where the C: is located, or in case that disk only has one partition, the first partition on the secondary disk
To be sure you are able to use your chosen partition for the relocated Users folder you need to set the drive letters manually before the sysprep is run. In Audit Mode you can do this for instance with Disk Management by manually changing the drive letters. In below example I want to secure that Users
folder will be moved to D
- Change the optical drive letter to something at the end of the alphabet, I use X:
- Change the drive letter of the partition or disk you intend to use for the Users folder to D:
- If the partition or disk you want to use already has a letter D:, change it to something else, close the Disk Management, open it again and change the letter back to D:
See the tutorial at our sister site the Seven Forums: Drive Letter - Add, Change, or Remove in Windows - Windows 7 Help Forums
I recommend to always set drive letters manually to override the defaults.
