I have a regular Windows system disk connected via SATA and booting as drive C, no issues, everything normal, on a regular whatever (desktop, laptop, etc.).
If I disconnect the drive from the internal SATA port and connect the drive to a SATA to USB adapter and then plug the combo into a USB port, what changes need to be made to the Windows disk, so that the computer can boot into Windows from the USB port. The procedure would be to press F11 to get to the boot menu and then selecting the USB hard disk.
The changes should be reversible. I have no issues doing whatever to the disk prior to plugging into the USB port.
I was using Windows 10 (Pro? Enterprise?) with the April 2018 update.
Why? I was given this task as an assignment, just I do not know what I would need to do to resolve the issue. I tried the experiment with CentOS and that works fine; Mac too, though that is obvious as Mac is BSD Linux, just Windows does not work.
Note: I did see the video on how to create a bootable USB drive with Windows on it from scratch, but I want to take an existing Windows SATA disk and temporarily be able to boot from that drive, when connected to the system via a USB port. There may or may not be another drive plugged into the motherboard. That should not matter, as I specified the boot device as the USB SATA device.
What happens now is that Windows boots part way, throws a blue screen, and then a few seconds later reboots.
