I thought this would be simplicity ... definitely misthought!
Been searching for something, preferably portable, that will identify the currently active OS partition.
OK, that's prolly not clear, so here's an example.
Take a desktop with multiple partitions on the HD(s). Four (4) of these [bootable] partitions are loaded with the same OS, although there are variants within each. OK, sounds stupid, but special circumstances make some sense of it. Personally, I'd have done this with VMs, but, oh, well.
So what I'm trying to find is something that will let me identify the active partition w/o having to reboot. Drive letters are not reliable in this instance, as they can be changed within each OS partition.
I really thought this was going to be simple, but it's turned out to be a bear. Any thoughts that might be helpful?
