Hi bschwartz, We do need further information to help troubleshoot this issue. Do you know the specific version of DDP | E that you are leveraging? The E7450s we did have issues with early BIOS revisions and SED management due to a new way with how the data is passed from the drive to the OS. I would definitely suggest updating BIOS and using the latest version of DDP | E available. if possible, would you be able to open a ticket with support at 877.459.7304 Ext. 4310039 or via techdirect.dell.com
Hello. Strange problem here which occurs (so far) only on the new E7450 model laptops with DDPE installed. Only tried with Windows 7 Pro 64 bit installed. Anybody else getting this combination of DDPE/E7450/F8 safemode, or have any answers from Dell support?   Thanks.
DDPE causes F8 Safemode menu to freeze on E7450
