When using modern USB flash drives that are recognized as "External hard disk media" in wmic, using diskpart in version <= 1.0.3 results in the error that the Wizard.hta window remains empty during the task sequence step for partitioning the hard disk. Finally, the installation is completely aborted.

The problem does not occur when using USB flash drives that are recognized as "Removable media".

How can I determine what the USB flash drive is recognized as?

Run the following command on the CMD: wmic diskdrive get mediatype

Cleanup (version 1.0.3) can in some cases delete the USB storage drive used to boot the MDT-based installation instead of the actual primary hard disk.

This behavior occurs, for example, on a factory-configured Dell 5420.

The cause of the problem lies in the BIOS configuration of the system, so that basically when booting from the USB drive instead of at least 2 hard disks (built-in hard disk and USB storage drive), the diskpart command used only recognizes a single drive. By calling the option sel dis 0, this - in this case the USB storage drive used for installation - is selected and finally deleted via the clean switch.

Workaround:
To solve the problem, change the option for "storage SATANVMe operation settings" from RAID to AHCI/NVme in the BIOS of the device.

Cleanup (up to version 1.1.6) can, in cases, delete the USB storage drive used for booting the MDT-based installation instead of the actual primary hard drive.

This behavior occurs on all computers where either no internal hard drive is installed or it is not appropriately connected (power cable / data cable).

After starting up into WINPE and the GUI appears, it tells that it only detected 2 logical drives. We are staging our devices only with a C: Drive. Any Chance that we i can get it to work?

Thanks a lot for your work.
