OK I know it has been covered over and over how to boot a WinPE from an external USB drive. Thanks to these forums, I got mine working. However, I have a problem. I have a highly customized install DVD that we use for my workplace. After booting WinPE, it uses Ghost to lay down an image on the drive. The Ghost file (.gho) is about 4GB. This means it will not fit on my FAT partition which needs to be 2GB or less. I was able to hard code the drive letters into the batch files to get it to run ghost from the second partition after booting WinPE, however, this is where I have a problem. Depending on which computer I plug into, WinPE seems to mount the USB drive partitions as different letters. So I need to go in each time and find out what the drive letter is for my econd partition and then re-edit the batch files to point to that drive letter. Is there anyway to configure the WinPE so that the Ghost partition always mounts as a certain drive letter, or somehow set a variable like %TargetDrive% to that partition? That way, I can use the variable and not a drive letter. Any help is appreciated. Vito
