I have an issue with Dell Vostro 3590, but same problem could happen with any model of series Inspiron, XPS, Precision, Latitude, Alienware, etc.

I placed an image to drive of the laptop. I used same image many times.

Now I cannot boot to the image.

The image is a sysprep Windows 10 installation.

How could I boot in my syspreped Win10 image?

 

Error: "Warning message. No bootable devices found".

SupportAssist Pre-boot system performance check

 

================================

P.S. What a shame for Dell. New Dell laptops are factory locked!

BIOS does not allow me to do a Legacy boot (BIOS states "NOTE: Legacy Boot mode is not supported on this platform").

It seems Dell tries to convince us "Legacy boot" is a feature. No, it is not. It is not applying a feature. Forbidding Legacy boot blocks us from using most of old Boot tools. Dell becomes an enemy of most of open source community!.
