Hi,

I've been looking but can't find the right info. If it exist please point me the the correct thread...  :embarrassed:

I'm trying to create a USB to boot either BIOS or UEFI. They should use the GRUB4DOS and GRUB2 boot menus. I like the keep thing the same...  :whistling:

I'm using the "Copy to USB-Device" script with the "Add Grub2-EFI" option selected.

Booting into either BIOS or UEFI it works as advertised...  :great:

I then add other boot.wim files to the \sources\ folder and edit the BCD and menu.lst files accordingly under GRUB4DOS. Booting into BIOS  mode I can select the different boot.wim files with no problem.  :smile:

The problem is doing the same on the Grub2 via UEFI...  :frusty:

I found some info on doing this with the x86 and x64 under GRUB2 but I need to be able to do this with multiple x64 boot options and more than two...  :confused:

Any assistance appreciated...  :new_here:

Thanx...
