Grub hell. Can I just delete the EFI partition and reinstall ubuntu?

Rotwang2 · 02-08-2020, 05:46 PM

ok hold on I'll boot into the iso on the real computer

Rotwang2 · 02-08-2020, 05:50 PM

Am I doing this wrong:

Code:

ubuntu@ubuntu:~$ sudo mount /dev/sda3 /mnt
ubuntu@ubuntu:~$ cd /mnt
ubuntu@ubuntu:/mnt$ more /etc/fstab 
overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0
ubuntu@ubuntu:/mnt$

If you saw that from the pastebin dump that could be the fstab of grub or whatever loads disks before booting the os right?

I mean the bootloader has to have it's own fstab right? That's before it loads an OS...

yes, compare

Code:

more /etc/fstab

to

Code:

 more /mnt/etc/fstab

you will get the same results regardless of what directory you are in, if you cd to /home you will see the same results

oooohhhh because I didn't chroot. aha. Man you're good.

OK I commented it out. I'm assuming I should also move swapfile.bak back to swapfile right? Or well wait it doesn't matter now that it's commented out right?

Code:

ubuntu@ubuntu:/mnt$ more /mnt/etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

No, The bootloader calls up the kernel and initrdfs, they do the heavy lifting so to speak

leave it alone for now

Rotwang2 · 02-08-2020, 06:04 PM

ok here I go

Rotwang2 · 02-08-2020, 06:13 PM

Same emergency prompt except interestingly this time it didn't throw the complaints about not finding swap.

And not only that but I just checked and it didn't make a new swapfile!

colorpurple21859 · 02-08-2020, 06:16 PM

what are the errors in the last 10 - 20 lines?

Hey you know what I just thought of- I can set up an ssh server on the live disk and set up port forwarding and you can come in and see and mess with stuff.

colorpurple21859 · 02-08-2020, 06:24 PM

before the emergency prompt, you should be able to scroll up with shift-pg up

Rotwang2 · 02-08-2020, 06:25 PM

Oh the emergency prompt is right at the top of the screen. I'll find
the pic I posted hang on.

Most of the items I look at to figure out what is wrong you have already posted.
