Can you post your complete /etc/default/grub.
I’d first revert the change you made to GRUB_TIMEOUT and set it to 5 again (what it was)
update-grub
and see whether that has some effect
The file looks ok otherwise.
just FYI:
you uncommented
GRUB_DISABLE_OS_PROBER=false
the original was:
#GRUB_DISABLE_OS_PROBER=false
this had no effect because
this is the default already - you did not need to uncomment that - only if you wanted to change it to “true”

No change after a grub-update and restart. Still need to manually write exit.

I did not comment or uncomment any part of this file. I only changed the numbers of the first two lines.
Then you probably need to reinstall Grub2.
How do I do that?
mkay - for me (and in the .pacnew file I have) it is commented out
but I did not check this one with Manjaro - I’m at Arch (EOS) at the moment
doesn’t matter - was just some info and the line is ok in any case
so: please disregard/ignore what I said about that
This is what I get when I run the sudo update-grub command if it’s any help:

This is what I see every time I boot my PC:
Pressing keys won’t exit it. I need to write exit.
thats strange - it does not jive with what is in the config file you posted
but I can’t help - I only have one system and no experience with two or why os_prober would not work
So is there a specific way to fix the os_prober issue? Again I don’t know if it’s related to BIOS setting but considering the fact that this hard disk has only one OS I would imagine the existence of other OSes on other hard disks shouldn’t matter one bit to Manjaro.
Perhaps the system info and GRUB screen picture that I posted may help.
it’s not even sure that that is the issue
in fact it’s likely not
I think already said that I’m not even sure that I understood your description of the problem you have.
Why would you end up, without so much as a keystroke, in the grub rescue/edit mode
is the question I’d have.
ps:
perhaps try taking the picture of your monitor without a flash -
so there is actually something to see in the picture 
the screen is bright enough by itself - the camera flash does not help … quite the contrary - as you can (not) see
and use an external service for the pic and link it here
just as you did with your grub config
I recommend to delete the one in your post above
it’s rather useless anyway
I am out of my depth here, so this is just speculation, but with so many drives (including a mix of MBR and GPT), I wonder if there are multiple copies of GRUB installed. That could explain why your GRUB doesn’t seem consistent with your settings.
Try setting it to 1 so it times out immediately or -1 to wait for a selection(multiboot etc). Being set to 0 may be why your sent to a shell.
Of course
update-grubAlso this:
https://unix.stackexchange.com/questions/198003/set-the-default-kernel-in-grub
Notice it makes reference to:
It could be very likely that this grub, which is booted into CLI, is not the grub of Manjaro.
How is that possible if there is only one Linux OS installed?
I changed it to 1 and this was the ouput to sudo upgrade-grub:

Restarted the PC. Still got the CLI GRUB menu.
Image Edited.
On a side-note I asked GPT 4 the same question and it suggested that my GRUB was corrupted and to try this:
It appears that you are seeing the GRUB command line interface (CLI) instead of the GRUB menu. This can occur due to improper configuration or a problem with your GRUB installation.
To resolve the issue, follow these steps:
1. Boot your computer using a live Linux USB (the one from your Manjaro installation should work). Once you have booted into the live environment, open the terminal application.
2. Identify the partition where Manjaro is installed by listing the available partitions:
sudo lsblk -f
Take note of the partition that contains the Manjaro file system, e.g., /dev/sda1.
3. Mount the Manjaro partition:
sudo mount /dev/sda1 /mnt
Replace /dev/sda1 with the appropriate partition from the previous step.
4. Chroot into the mounted partition:
sudo manjaro-chroot /mnt
This command will put you into the root shell of the installed Manjaro system, allowing you to fix the GRUB configuration.
5. Reinstall the GRUB bootloader on the appropriate drive:
sudo grub-install /dev/sda
Make sure to replace /dev/sda with your primary boot drive (but not the specific partition, just the drive letter). Do not include any numbers at the end of the device name, as we want GRUB installed on the entire disk.
6. Update the GRUB configuration:
sudo update-grub
7. Exit the chroot environment:
exit
8. Reboot your computer:
reboot
After rebooting, your computer should show the GRUB menu with a list of installed operating systems, including Manjaro and Windows 10.
If the issue persists, it might be necessary to check for errors in the /etc/default/grub configuration file or do a fresh reinstallation of your Manjaro Linux system to ensure a clean GRUB installation.
Wouldn’t this make me stick to a single kernel? I don’t really have an opinion on which kernel to use; I just want to stick to the latest one.
Don’t read random suggestion like that, use the Manjaro WIKI for information and procedures.
Cita ```
If you think an error has occurred, please file a bug report at “GitHub - Antynea/grub-btrfs: Include btrfs snapshots at boot options. (Grub menu)”
This error message makes me think that I install that?,because?What do you mean?
re the mention of multiple drives:
You may have installed Grub to the wrong drive and keep booting from it
and update Grub updated the configuration of one that isn’t used?
Don’t know.
os_prober should be active, when looking at your configuratio - yet it apparently is not
Another issue could be that you mixed mbr and gpt partitions Windos one variant, Linux the other?
It is entirely possible to do that - but of course it will not work … not easily anyway.
Again: don’t know.
I have no idea how it is possible that you, without a keystroke, end up in the Grub edit menu. 
That should never happen - not without you doing something (pressing a key at the right time …)
Don’t be fooled by all the media hype, telling you it is an AI and thereby presuming that it indeed knows or even understands something.
Google (or another search engine) and your own reading and discernment is way better.
It’s not designed to be an expert system - it’s designed to produce text that appears to make sense -
it will give you an answer - but that doesn’t in any way mean it is sensible or current.
