Well this is sort of a warning of sorts to those of you who (for any reason) change the permissions for the Macintosh HD to "Everyone: No Access"...
Not thinking straight this morning I was trying to get one folder to be shared from my Mac to my dads Win 7 laptop. Well when I enabled file sharing and shared only one folder, my entire HDD was shared, not a clue why but that's for another forum thread...
I changed the permission of Macintosh HD to Everyone: No access. Yes, that makes perfect sense, NOT! So I proceeded to log out, and then it just froze. My fans ramped up to full speed and I freaked. I forced it to power off. I then went through my brain trying to remember how to access the recovery area upon boot. No key combo I tried worked, UNTIL I had plugged in my recovery flash drive and then tried CMD+R again. I don't know if it ran off of the flash drive or if it somehow allowed my HDD to boot into recovery, I have no clue. I first tried repairing permissions on the drive through Disk Utility... That didn't work at all. Then I saw the option to recover from the Time Machine backup, so I did. What a relief!! It worked!!
Now I"m up and running again. Luckily I had a backup from about an hour before I screwed up the computer. So I didn't lose any data as far as I can tell.
So just a warning to you newbies (and perhaps not-so-newbies to the Mac world...) DON'T change the permissions of your main disk!! Now I just have to figure out how to properly network our computers.
