PopOs wont boot

[Stin6667]

Good day,

 

I have no idea what I am doing wrong. My pc wont boot.

I am trying to recover it.

I am following this guide.
https://support.system76.com/articles/bootloader/

As I am assuming the bootloader is to blame, I am a novice at linux so I can be wrong on that.

 

It says it is in legacy mode.

my sda goes up to 2. eda2. But that is [SWAP]. And I have no clue what that means.

so following the guide it says: sudo mount /dev/sda2 /mnt

But it won't mount. When I tried. it says "unknown filesystem type "swap""

 

This pc serves as my server, jellyfin, music etc. I don't mind loosing everything. But I would prefer not to. As It took a long time to get working how I like it.

What I did before this: 

(Now, I am not sure if I did this or not, but I think I did) I saw updates and installed them.

I edited the /etc/fstab so it can read specific folders in my NAS. I have done that. I noticed that I didn't name a file properly ( file name). So I corrected it. So, I restarted it so it can go into effect. I have done this many times before without any problem. ( I copy past and edit previous lines that work)

 

Any help will be appreciated it. 

I am barely a novice here. I understand windows better. So please go easy on me. thanks

You need to mount the root partition (that contains your os) as /mnt,

What is the output of lsblk? You should have a partition with a / set as mountpoint.

I copied it from the terminal ( I put in a usb with pop-os ( closed the install program)

Your root partition is sda1, so the correct command should be

sudo mount /dev/sda1 /mnt

 

[Stin6667]

I doesn't say [swap] anymore

 

as i tried using the swapoff sda2 and zram0)

[Stin6667]

The I am going to input this :

for i in dev dev/pts proc sys run; do sudo mount -B /$i /mnt/$i; done
sudo cp -n /etc/resolv.conf /mnt/etc/
sudo chroot /mnt
apt install --reinstall grub-amd64 linux-generic linux-headers-generic
update-initramfs -c -k all
sudo update-grub

Thank you. I should I put that code for the legacy bios boot?

I am assuming I input this next?

for i in dev dev/pts proc sys run; do sudo mount -B /$i /mnt/$i; done
sudo cp -n /etc/resolv.conf /mnt/etc/
sudo chroot /mnt
apt install --reinstall grub-amd64 linux-generic linux-headers-generic
update-initramfs -c -k all
sudo update-grub

I did that but, It still wont boot. It says I am in emergency mode. After logging in, type "journalctl -xr "exit

It also says
1)SGX disabled by BIOS

2) No firmware reserved region RMRR

system logs, "systemctl reboot" to reboot, "dystenctl default" or "exit"

No clue what that means

Thank you for your help. I fixed it, it wasn't the boot. It was when I changed the fstab,  I edited one of the other lines I wasn't supposed to
