Greetings I am running Lubuntu on an older laptop and everything was working perfect. I shut-down the PC last night and went to turn it on today, and am only getting a black screen. Just hangs on the black screen. If possible, I would like to avoid a complete re-install, but if that's my only option I can do such.

I am currently botting Lubuntu from a flash drive on said PC and everything seems to be working A-OK. I have checked the obvious, i.e. boot order and it is set to boot USB 1st then Hard Drive 2nd. What other steps should I take to get this sytem booting?

EDIT ->
Upon my further researching it seems that maybe the laptop can no longer "see" the hard drive. Is that what the fdisk output below is showing?

@jmarket -> The drive was working fine, I shut down for the night and turned it back on and get the message. I have used a USB to SATA adapter and connected to the drive to a windows machine (which I understand better, lol) - and when I plug it in and go to computer management I see this

However, the drive is not auto-assigned a drive letter. Maybe somehow the MBR is corrupted/lost?? (shooting in the dark here) - is there a way to get this drive operational w/o loosing data?

@jmarket - no worries. Hope you have a wonderful Thanksgiving. If I understand the second link properly, if my drive is mounted as sdb to check and repair I would simply run this command, correct?
Code: 
fsck -y /dev/sdb
