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?

  • Done properly, it will use the drive it boots from, the USB. However, based upon the second half your description, you might not be doing it properly.

    The drive designation can change between reboots causing the /dev/sdXX to change. I did write up this answer a while ago kind of showing that: askubuntu.com/a/693729/231142

  • The thing is (as ridiculous as it sounds), my device has only one working USB port.

  • I keep a Windows virtual machine on USB. When I plug it into a different computer I need to create a virtual machine with "Use an existing virtual hard disk file". which only takes seconds. Nov 13 '19 at 9:49
