New Ubuntu asker here,
If I install Ubuntu in a VM and write the VHD to a USB, will it request data from the location it was installed to (/dev/sdXX) or the port it boots from (/dev/sdXY)? For reasons I can't explain, I can't install it directly to a USB. I've tried searching but have only found guides on how to install it directly to the USB, however I have seen videos of what I am describing from 2-5 years ago. Does the Ubuntu install system from 5 years ago still work the same today?
