This problem has been sporadic, until now.
Power on>Bios Splash
Enter Bios Password
Enter HDD Password---------->Keyboard works up to this point.
OS Menu List is displayed. It defaults to BackTrack. Which I like, because that OS has good security. But I prefer to choose Mint for everyday use.
Since the keyboard is unresponsive, and I only give myself the default time to choose an OS, I get stuck with BackTrack.
I tried entering other commands, like 'e' and 'c', but I still get no response.
Any ideas? Perplexed? Me too!
Update: I just downloaded grub2 from apt. Ran a script required by the package manager, which gave me the option allow Grub2 to automatically update/overwrite Grub. GrubCustomizer works now. That's cool.
