Can't get to Grub Menu even after running boot repair - Windows 10/LXLE dual boot

[pgslmatias]

This is the output of boot repair: https://paste.ubuntu.com/p/QxV9NKDBnk/

At first I had Windows 10. I created an empty partition with 100 GB and I burned a USB with LXLE and installed Ubuntu by selecting install Ubuntu alongside Windows 10.

Everything seemed ok. When selecting boot order in BIOS I have as options Windows Boot Manager, my SSD and lxle. When I put lxle first in the boot order I only get to the GRUB terminal, I can't access the menu to choose between Windows 10 and LXLE. If I type exit at the terminal it boots to Windows, and it does the same if I choose Windows Boot Manager or my SSD as the first option in BIOS.

I ran boot repair from the live USB, but nothing changed at all. I can access Windows 10 perfectly, but have not been able to get to my lxle installation.

I have Secure Boot turned off.

What's the next step in debugging the problem?

Moved to other OS since not Lubuntu.

What model Lenovo?
Do you have Windows fast start up off? Note that Windows updates may turn it back on.

Grub only boots working windows, so fast start up must be off. Also Windows must not need other repairs, like chkdsk.

It is a Lenovo ideapad 3.

Right now Grub is not booting anything, I can only boot into Windows, not into Ubuntu.

As for turning off fast startup, I don't have the option to do so. It doesn't appear and as such, according to https://answers.microsoft.com/en-us/...0-718446f9d5f8 I am supposed to edit the registers. I'm not sure I should do that though: Windows is working perfectly.

I don't understand how a problem with Windows would make Grub not show the menu and show the terminal instead, and not being able to boot into Ubuntu. I could understand a problem with Windows not allowing me to boot into Windows from grub, but that's not what is happening.

The output from efibootmgr is in the Boot-Repair summary report.

Can you directly boot this from UEFI boot menu?
Boot0001* lxle

Are you then able to get grub menu, or maybe press escape right after vendor logo but before grub menu normally appears?
And then boot recovery mode? Or second line in grub menu?

I'm not sure I understand what you are asking for If you mean in UEFI try to boot into lxle, by putting it as the first option, yes. As I described in the OP, that's what I do and all I get is the terminal, not grub menu.

If this is not it then I don't know...

Are you getting grub's limited terminal like grub> or Ubuntu's full terminal where it has not booted into the gui?

grub limited terminal

Can you from grub>run this?
configfile (hd0,5)/boot/grub/grub.cfg

OR:
set prefix=(hd0,5)/boot/grub
set root=(hd0,5)
linux (hd0,5)/boot/vmlinuz root=/dev/sda5 ro
initrd (hd0,5)/boot/initrd.img
boot


This should show partition, so above commands are at right partition.
ls (hd0,5)/
ls (hd0,5)/boot
