That is what Germany_chris was trying to discuss regarding speed.
If your RAM is too small, the normal symptom is that the OS runs too slowly. RAM needs to be far far too small before that stops an OS from running at all. Moderately too small makes it slow.
How much ram does your system have?
How painfully slow was Mint when booted from a USB? It would be a little faster if installed on the hard drive. If the speed wasn't terrible when booted from USB, you must have enough RAM. If it was painfully slow when booted from USB, you still might have enough RAM for it to work well when installed on the hard drive. It just is harder to be sure before trying.
When I ask how slow it was, I don't mean how slow for Linux to start when you booted the USB (that is a separate question). I mean once you had run a program in Linux how slow was it to run another.
