Hello,
I am trying to create a USB avast bootable device, no success.
I add created a post in wrong forum (
https://forum.avast.com/index.php?topic=303835.0), and now continues here.
the creation process goes up to the end without any problem
the boot order is usb/dvd/dd
the bios recognize UEFI
when I do manual boot, the usb does not appears in the list
I suppose the device is not bootable.
with disk manager, I see the device has a MBR
with powershell I see:
> get-disk
