Trying to boot from USB but getting "Operation system not found"
I have a Dell XPS15 working fine with windows 10 and Debian, but when I deleted the Debian partition I couldn't boot back to windows and started getting a grub error ( this meant that I had to repair the windows boot) so I created a windows 10 bootable USB drive and configured BIOS to boot from it but I get "Operation system not found"

You can try those following resolutions:
1. Rebuild MBR;
2. Enable or Disable UEFI Secure Boot;
3. Set the System Partition Active.
