***NEWSFLASH***
I
finally got Gentoo LiveCD to see my keyboard. The solution: Disconnect/reconnect its USB connector. Go figure.
At any rate, here is the output of "fdisk -l":
The drive is NOT currently partitioned, but I've tried to install Mint when it *was* partitioned/formatted NTFS. I was also able to perform the "dmesg | less" command, and it produced nearly 1,000 lines of output. It's too bad I couldn't capture it & post it using the "[code]" forum function here.
At any rate, I'm learning a LOT during this exercise! In fact, in order to "escape" the "dmesg" output, I experimented with "ALT+F4", and it finally threw me back into the command prompt. Then, in order to exit Gentoo, I tried "reboot". Lo and behold... it worked!
At this rate, I'll be a Linux expert in ... oh ... I don't know...
...about
forty-three thousand years, give-or-take.
