Ubuntu please help

[FrankieP]

Hey Goys.

I am having trouble launching my Jewbunutu.

When I get to the login screen for my bios this error message appears before I type in my passphrase:

Lvmetad is not active yet, using direct activation during sysinit
Volume group "ubuntu-vg" not found
Cannot process volume group ubuntu-vg

There is a solution here:

"Lvmetad is not active yet, using direct activation during sysinit" on boot?

However, I am not familiar with Grub, if I use Boot-Repair will it resolve this issue without affecting any of my data?

Looks like that answer was just to boot into older version of the kernel. And then set the older kernel as the default one to boot. Have you ever booted into this machine? I am in my phone now but can loom tommorrow at my installation. I don't use ubuntu as my main. But think i have a virtual with it loaded.

grub and boot-repair shouldn't mess with your data. They are most likely operating on separate partition(s) of the disk.

Even if you can't boot or you do screw things up, you should be able to boot another OS (say linux from USB) and mount the partition your home directory is on (say your primary disk /dev/sd0sN, where N is some small integer like 2) to access (read/write, e.g., copy) your data to another storage medium, if necessary.

If you don't actually have any data, then I'd just reinstall the OS, rather than spend a bunch of time fucking with grub. Hell, you may be able to reinstall while preserving your data (but it's a risk).

TBH the easiest way to fix these problems is by booting up with a live USB stick and backup up any data you want to keep then nuking the system and start over.

There's also a good chance that your hard disk is fucked anyway if you are getting grub or boot errors without any reason for it (e.g. if you didn't just do a kernel update or something). If that's the case go and get a new hard disk and put the old one in an external USB thing and copy your data over.
