Thanks everyone for all your input, but no one has answered my original questions. I will recap and add a bit more information that might be helpful. I'll use the MS convention for naming the partitions. I place a new HDD, unpartitioned and unformatted, into a laptop. I boot the laptop via a USB HDD that has 2 partitions. They System Partition of the USB HDD gets assigned C while the other partition containing the images is assigned D. I now use DISKPART to prepare the new HDD, clean | create par pri | format fs=ntfs quick | active | assign. Now the new HDD has the drive letter of E. I apply my Windows 7 image to the new HDD using imagex. However this image is only of the Boot Partition and therefore does not contain a boot folder in the root directory. To make this new HDD bootable I need to use the BCDBOOT command, but what is the correct command and do I need to run the command from a particular location? TIA Greg
