Boot Failure
 
Hi! I am running an old Lubuntu distro on an ancient MSI Wind Notebook. Today, it refused to boot up, indicating some kind of hard disk failure with the message "error: failure reading sector 0x802 from 'hd0'".

I am able to boot the machine with the Ubuntu Boot Repair utility from a live USB but not able to repair the bad sectors in question. Below is the BootInfo Summary generated by the utility.

At this point, I care only about recovering my files, not the device itself, which given its age and present shape, I expect to trash after this unfortunate episode.

Incidentally, I am unable to turn off the Secure Boot feature in my BIOS/Boot settings.

Any help in recovering my files would be most appreciated. Thank you.

In the future, try to pastebin or at least code tag encapsulate your log/output. That's a lot to dump in a post.

You said the issue was hd0... but I didn't see hd0 in the output.. is it actually sda2 (since that seems to be erroring)? Could be a bad drive. Could be a bad board or cable as well. Hirens bootdisk has a utility called "Victoria", which can both scan and remap bad sectors, depending on the drive. Might be worth a shot to at least scan and if any bad blocks are reported.

Your boot repair is missing a lot of data that generally shows up, no Grub files show on the drive. How old is old, which specific version of Lubuntu is installed? Have you tried running fsck on the Linux partition (sda1)? Create a mount point and mount it to see if the folders/files are accessible. If not, best to get testdisk to try to recover your files. See the link below and be sure to read the Step by Step instructions before beginning. There is a link to it on the page under Documentation.
