You know depending on your flexibility this could be booted from a USB expansion drive SSD or otherwise.
Would still need to select the boot source in the boot screen, or most likely in my case from the actual bios.
Now that is a significant hassle to switch OS's.
But I was wondering, since my machine is pretty old if the placement of the data cables has an effect on boot sequence? You remember a just a few years ago we had to deal with jumpers either on the drive itself or the MB to select Master and Slave.
Do you think I have a data cable selected as master by the system? Would it be marked somehow? Seems unlikely but so does the current situation.
All my old drives are completely accessible now including the new SSD, and anything I plug in. I'm afraid to actually use it for fear of fucking up the Win 10 Pro that is on it and completely boot-able. (sans the old drives at this point) bios may make this booting selection more reliable but haven been there yet.
