[SOLVED] 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!!!

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:

You can boot your linux system through Super Grub2 disk, Download the iso from here (http://www.supergrubdisk.org/) and create a bootable USB After successfully booting linux , reinstall grub-efi as follows : grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=debian --recheck --debug /dev/sda update-grub

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

configfile (hd0,?)/boot/grub/grub.cfg

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.

sudo grub-install

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.

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
