First of all, a big "thank you" to all of you knowledgeable folks who chimed in with info. I was swamped by the volume of responses!
Secondly: Lacking any hint of a coherent game plan, I set about futzing with this on my own. Here is what I did, and why i ended up doing a Windows Restore an hour later:
--Like I promised, I downloaded the VMware Player. i had hoped to install and run linux-based programs out of this app, but that in itself appears to be fantasy. As best as I can figure, you can't actually INSTALL anything to the player, at least that it will remember the next time you load the player. Smart People: please confirm or deny this suppostion.
--I went looking for linux to run on this Player of mine (free downloads become "mine" the moment they hit my hard drive). I first started downloading Fiesty Fawn (and a big thank you for not being on 5 CD's), but as I read more about this stupid little player of VMware's (stupid things are other people's property and/or fault), the hopelessness of it began to dawn on me. I needed a "linux appliance" to run on the player, or else the darn thing's just going to sit there looking at you, daring you to make the first move. Afain--right or wrong?
--The VMware site features a jumble of links to such appliances, and I chose one pretty much at random. "Linux Mint" got the nod, mostly because it said "linux" and was under my mouse cursor. "This must be the one!" I shouted gleefully, since NONE OF YOU came up with a better one.
--Well, a "linux appliance" is really such a linux live demo CD image preconfigured to run inside the player window. As such, it loads a honkin mess o'stuff into RAM, which is the only thing on a laptop in shorter supply than disk space. Recall, the only reason I wanted to do it this way (other than sheer impulsiveness) was to conserve laptop resources while getting linux capabiliy. PSHAW! (Appologies to G. B. Pshaw)
--Worse yet, this dingleberry hung on to the RAM like a, well, like a ram-hog. So that's where the Windows Restore came in, thankfully.
Smart Folks: Where is the proper path out? I want to run linux on my laptop, although only occassionally and not in a mission-critical manner. Do I:
1. Try what I did again, only intelligently this time, via Somebody Smart telling me how to do it?
Or,
2. Do I run a dual boot on my limited HD space, allocating space not just for the program but related data (and necessarily deleting audio tracks to make room).
Or,
3. Is there a way to run linux completely off a (bootable) USB drive? I can just pictue a 8 gb thumb drive being plenty for the time being.
There you have it, AFAICT. Open the floodgates--here come the responses!
