Using UNETBootin to install Linux Mint on a line of Dell Optiplex 760s
Hopefully this is right place for this.
I've used UNETBOOTIN to configure a USB stick with Linux Mint and am trying to install it on about 25 old Dell Optiplexes that can't run Windows 7. The process has worked on about 8 of the 25 computers. The others get the blue screen that asks how you want to boot (where you'd normally select Start Linux Mint so that you can run the install executable) and then it just sits at that menu forever.
I've tried taking the hard drive out of a "bad" computer and putting it into a "good" computer that installed Linux Mint properly. The install works fine on the good computer with a bad drive, but as soon as I put that previously bad drive (that now has Mint installed on it) back into the bad computer, it just sits at a blinking cursor forever (I've left it overnight). At this point, I'm at a loss as to what else to try. Is there some way I can boot some kind of diagnostics to see what problem its having with booting? It definitely seems to be a hardware problem, even though my understanding of the Optiplex line is that they're supposed to be identical hardware-wise.
