Problem solved. I contacted Dell support and they pointed me in the right direction. I used the drive OOTB, which apparently is not a good idea.. So I used Windows Disk Manager to remove the partition/volume off the USB drive. Windows then creates a 'basic disk' and divides it in portions of max. 2 TB. Converted the disk to 'GPT', this creates one large drive. Created new single partition, performed a looong format and after that, machine boots without error. Simon
PowerEdge T320 runs Windows 2008 R2. If I hook up a 3 GB USB drive and reboot the server, the 'Starting Windows' briefly appears and then it halts with an error. Didn't make a screenshot, but it's something like 'UEFI pre-boot environment error'. If I disconnect the USB drive, Windows boots without problems. How do I get Windows to boot with the USB drive connected? Simon
