Some of you have probably been following the saga, How to gain access to files/folders on a drive that originated from another machine . . .
For those that haven't, it's the backstory for the question that follows.
I obviously know that you can boot from USB flash/thumb/jump drives and have done so many times in the past. But I seem to recall that this will not work for an external USB HDD, like a typical external USB backup drive.
I am getting desperate enough that I'd like to try booting from the HDD that had been the boot device in a now-defunct machine on the new machine, just for the purpose of getting access to data I can't seem to get any access to via every conventional method I know of. But I'd really, really prefer not to have to actually transplant that drive in to the new machine, but would prefer to just change the boot order and tell it to boot from USB and have it use that old system drive that's connected via USB cable be the boot device. Since it was the OS system drive, all the bits necessary for it to be a system boot drive are already there.
Can this be done?
