Lubuntu Will Not Boot

[BobGoblin]

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?

Hi there @BobGoblin

That’s exactly what you’re seeing. What happens in BIOS? Can BIOS see the disk? It could either be the drive isn’t initiated or the drive is dead.

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?

Hey sorry for the delay. Preparing for Thanksgiving this week

Try the following guide to mount a drive in Ubuntu. https://www.cyberciti.biz/faq/mount-...-ubuntu-linux/

After mounting it, follow this guide to check the filesystem for errors. https://www.linode.com/docs/quick-an...disk-problems/

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?
[ICODE]fsck -y /dev/sdb[/ICODE]

[jmarket]

Correct
