Your local spellchecker here for you! On page 13, your 2 partition diskpart script, you have the second partition (the one with E: ) to get drive label="CDRIVE" the same as the first partition which actually is the C drive! However as an alternate script to deal with the CD-ROM drive letter being there, you could also do this: sel vol d assign letter=e As with deploying a stored Windows 7 image, you do not need to give the system reserved a drive letter. Since a Windows 7 WIM is stored sysprepped, it will automatically take care of the System Reserved partition on reboot. So a good scenario to redeploy a Windows 7 image would be to NOT assign a letter to the system reserved partition, and make the OS volume get the C drive. Also, the OS volume should be active, not the system reserved partition. But obviously your example will put a System Reserved partition and the rest of the drive a Logical Volume... Can Windows boot from a Logical Volume? Here is my (modified) Windows 7 example: sel disk 0 clean create part pri size=5000 format fs=ntfs quick label="system" create part pri sel part 2 active format fs=ntfs quick label="OS" assign letter=c exit A couple notes. After creating the first partition, you do not need to do "SEL PART 1" because it will be selected automatically. This is only for the first partition. If you do a LIST PART after creating the partition, you can see it is going to be selected already.
