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

colorpurple21859 · 02-08-2020, 12:22 PM

your should be able to skip the update-grub command, if you already run it before.

colorpurple21859 · 02-08-2020, 12:27 PM

This

Code:

sudo mount --bind /dev /mnt/dev
sudo mount --bind /dev/pts /mnt/dev/pts
sudo mount --bind /proc /mnt/proc
sudo mount --bind /sys /mnt/sys
sudo mount --bind /run /mnt/run

and this

Code:

for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i

basically does the same thing. For some reason it is easier for me to remember the mount --bind commands versus the single command.

ok restarting now then

Rotwang2 · 02-08-2020, 12:48 PM

OK same results.

Btw if it matters- the grub menu is the same (for both "ubuntu" entries I pick in bios):

(If I reinstalled ubuntu from scratch and in the "Something else" I set the efi drive to mount at /boot/efi or would I still be screwed?) I'm will to keep going just for fun but I'd be nice to know I have a fall-back.

boot the live iso mount your root partition to /mnt
edit the /mnt/etc/fstab change this

Code:

/swapfile                                 none            swap    sw              0       0

to this

Code:

#/swapfile                                 none            swap    sw              0       0

Then try to boot your system

Oh it's good to see you back I was about to give up and try reinstalling by properly mouted at /boot/efi. (that won't work right?)

OK my fstab doesn't have a swapfile entry, all it has is:

ubuntu@ubuntu:/mnt$ more /etc/fstab
overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0

So effectively its non-existence is the same a commenting out the line.

Btw there is a swapfile in /

(And yes this I'm doing that on the mounted / not the live disk) sudo mount /dev/sda3 /mnt

run this command

Code:

mv /swapfile /swapfile.bak

see if that does anything

OK here I go. (I think I know what you're trying here- I doubt it'll work but at this point we'll try anything ug)

Hey also have you heard of "swappiness"? Your method of changing the file name is much better but I figured I throw that at you.

ok brb.

Rotwang2 · 02-08-2020, 05:06 PM

Nope. Different results this time:

It's interesting that it didn't just create a new swap file.

colorpurple21859 · 02-08-2020, 05:09 PM

Rotwang2 · 02-08-2020, 05:11 PM

Not surprisingly it goes to the purple screen again for like 1 second and then displays the emergency prmpt again.

I'm typing this on my cell i've still got it open
if you want me to try any commands

colorpurple21859 · 02-08-2020, 05:32 PM

boot the live iso mount /dev/sda3 /mnt
nano /mnt/etc/fstab
comment out the /swapfile line with # at the beginning of it

Rotwang2 · 02-08-2020, 05:37 PM

Oh you missed one of my responses- there is no swapfile line in the /etc/fstab

colorpurple21859 · 02-08-2020, 05:41 PM

according to your paste.bin

=============================== sda3/etc/fstab: ================================

--------------------------------------------------------------------------------
# /etc/fstab: static file system information.

so either your looking at the wrong /etc/fstab or it has changed for some reason.
