Is there a way to install ubuntu 7.04-8.04 in VPC 2007? I can't do it because it just goes black. :-(
I can't say for VPC, but I would suggest getting the freely available VMWare Player - it runs both those versions of Ubuntu (and 8.1) fine. You'll need to download a small VMX (see EasyVMX) from the web but that's fairly painless.
The only reason I keep VPC around is because it's the only one I know of that still runs OS/2 :-).
You probably won't ever have much like with Virtual PC, to be honest. (It was developed with only various versions of Windows in mind, and from my experience there's always some sort of problem running any linux distro under it.) I would recommend VMWare Player, as suggested above, or alternatively VirtualBox, which has worked very well for me in the past (it runs certain linux distros best, though I can't remember which ones).
Hmmm... I have 7.10 installed in Virtual PC.
I don't quite remember but I think I also had an issue with 7.04, so I gave up. I came back later when 7.10 came out and it installed from the ISO with no major issues (that I remember).
