How can we install a windows in Detachable Notebook using bootable USB?

First of all, is the USB is bootable?if not then create it Bootable it's easy by cmd commands open cmd

>>diskpart>> list disk>> select disk (Number of USB)>> clean>> create partition primary>> select partition 1>> format fs=ntfs quick>> assign letter (any partition letter that is avalible)

>>exit

if it's bootablethen please go in BIOS and check which BIOS you have is it legacy or UEFI, On both, we are always required to disable secure boot.Hopefully, the issue should be resolved. Try on both,

Hi

I think it`s matter of compatibility of a version of OS and Acronis .

I did restore windows7 backup with acronis version (I think) / but when I I did that way with windows8 it failed.

I think it is better to try with a lower OS version.
