Hello,
Can’t boot system, goes to emergency mod.
Command “systemctl --failed -l” show me
UNIT LOAD ACTIVE SUB DESCRIPTION
Home.Mount loaded failed failed /home
What to do?
First try to mount manually to see what the error message is.
mount /home
Your HDD is failing. At this point I’d try to use dd_rescue or similar to make image of failing drive and then tried data recovery programs on this image to salvage as much as possible. If you have recent enough backup (or simply do not care about content) just replace HDD.
