I've used the "Recovery Disk" function in Windows 8.1 to create a bootable USB drive with the factory defaults for a laptop. Now I plan to wipe the laptop and install Ubuntu on it.
I'm not comfortable with having a USB drive as my only backup for the factory image (the reliability of these drives is legendary \s). So a more reliable backup is in order.
Is there a way to make Windows Recovery write directly to a mounted image file instead of a USB drive? Alternatively, can I create a bootable image file from the USB drive, including all the boot info and the data? This might be something like
dd, but in Windows for a UEFI-enabled bootable drive.
The end goal is to maintain the image file in safe backup and write it to an actual USB drive only if/when required for a factory reset.
