So I tried using MBR instead again my Dell tablet would not boot the flash drive. Please select an EFI bootable ISO or set the Target Type to BIOS. When using UEFI Target Type, only EFI bootable ISO images are supported. However, when I first tried this Rufus wouldn't let me, citing this error message: Rufus lets you select among the following three Partition schemes:Īnd the tutorial I was following said explicitly that you need to use GPT. Then I tried to flash it using the Rufus utility. Oscdimg -m -o -u2 -udfver102 -bootdata:2#p0,e,#pEF,e,befisys.bin C:\Winpe\ISO C:\Users\Administrator\Documents\winpeuefi.iso

I used this command in order to create the ISO (in this example I put my PE environment in C:\Winpe): The next guide starts out the same with steps #1 and #2 above, but then recommends creating an ISO file and using a 3rd party utility called Rufus to flash that ISO onto the USB stick. I tried turning off Secure Boot that didn't work either. When I edit the UEFI configuration on my Dell tablet (what I'm trying to boot on), I see my flash drive as a boot option, so I changed the order to say it should be #1, but that didn't work.

I've got the Windows AIK (Automated Installation Kit) installed on my server because that has the source files for Windows PE. There are loads of tutorials, all of which I've been trying in succession, but it seems no matter what I do this stick will just not boot. I have been trying for more hours than I'd care to admit to get a bootable UFD (USB Flash Drive) with Windows PE on it.
