Seeing minimal bash-like line editing is supported when booting to grub for lubuntu 20.4
 

I have successfully installed lubuntu 20.4 on unallocated space and grub is installed, I just have to change to ubuntu in boot options. unfortunately, grub says Seeing minimal bash-like line editing is supported. I don't know what to do because it is completely unusable and I cant get to lubuntu but I know it is installed. Any help would be appreciated.

Take a screen shot upload it to OneDrive, Google Drive, Pastebin (set proper permissions of course only the folder with that pic and not expose your whole drive :)) or other sources, it would be easier for others to figure out what is on your screen.

Good luck!!!

Thanks for replying! here is the screenshot.

the screenshot is exactly what is on my screen.

this page has a description of how to boot from the grub prompt.

You will might need to do a grub rescue, see this link: https://www.linux.com/training-tutor...-grub-2-linux/

Or try as Cordx suggested.


See if this one will help also:

it's a post from this link: https://unix.stackexchange.com/quest...e-after-reboot

i found that page right after i posted my suggestion. it is a much better description. i would recommend starting with this one instead.

For the lazy noob:
https://www.supergrubdisk.org/rescatux/

If you know what drive/partition lubuntu is on
the ? represents the partition number counting from 1, If it is on a different drive, drives count from 0.
Then once booted in open a terminal run if this is an efi system.
If not add /dev/sda, this may be different.

Thanks I think it is because I rebooted without removing the usb because after I removed it and it worked. I would however still learn about this issue so thanks again.

Thanks, I'll check it out after studying. Really good of you to help linux newbies like me:)

I understand the second part, but what does the first code mean. Is it for a terminal or a file location? thanks

at the grub prompt
grub> configfile (hd0,?)/boot/grub/grub.cfg

all past suggestions not worked in my case.

I tried run grub-install, boot-repair but not solve my problems.

I have a double boot system with debian distro and with signed packages for boot security.

With signed image and grub-install (signed too) no error appear, but grub console appear again.



To solve, in my case:
grub-install write in /dev/sda2 your files in /EFI/grub folder (in sda2 windows SO put efi files in EFI folder)

Shutdown and Power on again

In grub console bash-like

ls command to view partition with efi files (hd0,gpt2). The first grub.cfg file is in grub folder
extract_entries_configfile (hd0,gpt2)/EFI/grub/grub.cfg command to run grub.cfg (firt grub config file)
then new error appear: "error: search.fs_uuid is not allowed to execute in an extractor"

The problem is the $prefix variable.
echo $prefix to view it's content: (hd0,gpt2)/EFI/debian

debian folder not exist!! That is the problem

I created debian folder in EFI folder and
copy grub.cfg (file in EFI/grub) in debian folder.

Then

Shutdown and Power on again

And RAN
