I’m trying to create a UEFI DUET flash drive using these tools:
Once I managed to create using the Tianocore installer but now I can’t - I don’t understand what’s going on
Creating a flash drive is not a problem but I can’t start the computer from it. The same happens in the Qemu virtual machine as I take a flash drive image to the .img file.
When booting from Tianocore version I have error:
When booting from DUET - REFIND version the machine starts from the next item on the Boot Menu list - DUET does not start and there are no DUET messages on the screen
I tried to clean the flash drive with zeros, I’m trying to create a flash drive under WinXP or under Win7 but it doesn’t help (diskpart in WinXP does not support USB flash drive and I use HP USB format tool - as advised in the Tianocore manual - Usage_Windows.txt)
I also found a ready image duet.img 50MB and after writing to a flash drive DUET always works on real or virtual machine Qemu - I can replace the EfiLdr20 file with other DUET versions.
Why can’t I start DUET from a USB stick created with Tianocore or DUET REFIND tools???
