Having to set root and prefix every time I boot on grub 2 "minimal bash like editing"

Question

I tried the alternative method shown here using boot-repair after the system didn't detect at all the linux bootloader (only windows option and the disc only (which I don't know why it appears) were in the bios boot order options and in the boot menu). Now the BIOS detects the bootloader (ubuntu is added to the list), but in this minimal bash mode.

I have to type the following lines to make it show the usual splash screen, just as I customised it:

set root=(hd0, gpt5) (this is my root partition)
set prefix=(hd0, gpt5)/boot/grub
insmod normal
normal

Why do I have to type this every time I boot? How can I solve it? I also tried to use boot-repair to reinstall grub completly ticking the purge grub option, but it still doesn't work

UPDATE: Nevermind, the computer died again (not because of me, the motherboard broke for the second time and I hope I can get the whole thing replaced). Thanks to the ones that tried to help me

It didn't leave anything. The link was https://paste2.org/ or am I looking for something else? — Tom, Sep 12 '21 at 23:38
Yes the link is incorrect. Try boot repair again and then copy and paste the link into your question. — WinEunuuchs2Unix, Sep 13 '21 at 00:32
I tried again and got the same link, which takes me to a page where I could paste a code, but I have no codes. I clicked 'yes' when it asked me to upload the logs to a paste bin. Do you know why isn't giving me any logs? — Tom, Sep 13 '21 at 12:44
When you look at this link: https://askubuntu.com/questions/1104855/how-to-make-grub-menu-appear-instead-grub-minimal-bash-like-in-booting/1105737#1105737 Make sure you click the second option to get a report. — WinEunuuchs2Unix, Sep 13 '21 at 12:57
You mean creating bootinfo summary? It still gives me this message: Please write on a paper the following URL: https://paste2.org/
If you are experiencing boot issues, indicate this URL to people who help you. For example on forums or via email. — Tom, Sep 13 '21 at 15:07
There is a problem. Because the link is missing / followed by a 6 or 7 digit number (or something like that). — WinEunuuchs2Unix, Sep 13 '21 at 16:45
I know, that's why I thinks this is so weird. I'll try to reinstall boot repair when I have the time and see how it goes. I will comment here when I get any results — Tom, Sep 13 '21 at 17:07

Because you haven't fixed grub yet. All you've done so far is allowed yourself to boot up from the grub terminal. You need to type the following from terminal once you have fully booted up:

sudo update-grub
sudo grub-install /dev/sda
shutdown -r now

Boot-repair doesn't always work. Did you get an error with grub-install command? Run ls /dev/nvme* and check that nvme0n1 exists. I think it's nvme0n1 that has to be used in the grub-install command for an M.2 SSD – Paul Benson Sep 13 '21 at 01:12
Report would show us details, so we can make better suggestions. But issue is that you are booting with an old install of grub, but have updated system and installed grub somewhere else. system is booting from old version of grub. May be that Windows is UEFi and Ubuntu BIOS or if now both UEFI, you have old BIOS grub installed? If UEFI system be sure to always boot in UEFI boot mode. Or you installed grub in BIOS boot mode without bios_grub partition. Or ??? – oldfred Sep 13 '21 at 14:31
I don't know what you mean by 'SYSTEM_DRV' partition. Not something I'm familiar with. nvme0n1 is the notation for your M.2 drive, just like sda is notation for an HDD, and in the latter case I would re-install grub with sudo grub-install /dev/sda as I've done many times before. I think to get a clearer picture, please post output of sudo parted -l and sudo gedit /boot/efi/EFI/ubuntu/grub.cfg into your question. – Paul Benson Sep 13 '21 at 16:06
Your efi partition is nvmeon1p1, and that should contain efi boot files for Win and Ubuntu. Nvmeon1p6 is also an efi partition. Maybe that's where your Ubuntu efi files are. For some reason it's showing up weirdly in the parted command. First we need to see what's in nvmeon1p1, So if you do sudo ls /boot/efi/EFI, what folders are shown? Also mount nvmeon1p6 - sudo mount /dev/nvmeon1p6 /mnt. Then need output for sudo ls -R /mnt. – Paul Benson Sep 15 '21 at 01:21
Your efi is showing Pop as your Linux system. Are you using Ubuntu or Linux Pop, because this is supposed to be a forum for Ubuntu, not dists based on Ubuntu? Having said that, you really just need 1 ESP, rather than the 2 you have. You have 2 pop files and 2 boot loaders, namely grub and systemd-boot, ie it's a mess. I'm going to suggest you just use nvmeon1p1 as your EFI and delete nvmeon1p6 eventually. I'll get back to you about that later. – Paul Benson Sep 15 '21 at 08:22
SInce the installer asked for a boot partition bigger than 500MB I created a new one (the original one was nvme0n1p1 with the windows boot loader). I guess I can't resize nvme0n1p1 so I should keep the other one instead and move the windows boot files to that one. And yes, its pop os. I though it would be no problem since its just ubuntu with some gnome extensions and minor changes, or that's what I think it is. Sorry about that – Tom Sep 15 '21 at 13:19
I'll get back to you later on. All responses by me will now be through 'Answer', which I'll keep editing where necessary, as comments are getting too numerous. Meanwhile can you tidy up your question and delete nvme0n1p1 output from /mnt/EFI/Microsoft/Boot/bg-BG: to /mnt/EFI/Microsoft/Boot/zh-TW: as they're irrelevant language options. Also delete your messages to me except your last 2. – Paul Benson Sep 15 '21 at 16:58
