Boot loader issues

[virstad]

I have a similar problem. For several days now, I have been offered 125 updates for testing branch.
When I perform these 125 updates for testing branch, the boot menu disappears and I am automatically logged into Manjaro without being able to select another OS, for example for dual boot.
When I select Stable branch, I don’t get a boot menu either.

Your post has been moved to a dedicated topic.

Please avoid adding your own request for Support to another member’s topic. A separate topic will allow others to help with your specific issue(s) without any potential confusion.

You have provided your system information. Thank you for that. I’m sure someone will help when they are able.

In the meantime, please rename the title to something that better explains the problem you are experiencing.

Regards.

@virstad

When I perform these 125 updates for testing branch, the boot menu disappears and I am automatically logged into Manjaro without being able to select another OS, for example for dual boot.

Your description didn’t seem immediately clear, but with fresh eyes I can see that it might only be a matter of configuration.

If I now understand the problem correctly, the easiest cure might be to edit the /etc/default/grub file directly;

---

1. To have the Grub menu display and the last booted OS set as Grub’s default boot selection, ensure that these lines are uncommented; change as needed, but this works for me:

GRUB_DEFAULT=saved
GRUB_TIMEOUT=5
GRUB_TIMEOUT_STYLE=menu
GRUB_SAVEDEFAULT=true

2. And then, uncomment this line (leaving it exactly as shown) to ensure other loaders are detected;

GRUB_DISABLE_OS_PROBER=false

Close and save.

---

3. Next, update the Grub configuration:

sudo update-grub

4. Reboot.

Welcome to the Manjaro community

As a new or infrequent forum user, please take some time to familiarise yourself with Forum requirements, and the many ways to use the forum to your benefit.

To that end, links are provided (below) - Please use them.

---

Be prepared to provide outputs from various commands when asked. It’s equally important to provide as much actionable information as possible in your first post, rather than simply indicating there is a problem.

Waiting for someone to blindly ask questions is also counter-productive – typically, nobody has a at their disposal – Instead, please help others to make informed suggestions, based on information you provide.

---

Update Announcements

The Update Announcements contain important information and a Known Issues and Solutions section that should generally be checked before posting a request for support.

System Information

While information from *-fetch type apps might be fine for someone wishing to buy your computer, for Support purposes it’s better to ask your system directly;

Output of the inxi command (with appropriate parameters, and formatted according to forum guidelines) will generate information useful for those wishing to help:

inxi --filter --verbosity=8

or the short form (preferred):

inxi -zv8

• inxi man pages (Arch Manual)

@Running `inxi` in `chroot`

If you need to run inxi from within a chroot environment, and find the output is laced with unexpected 12’s, please try again with:

• Add to the long form command: --color=0

Downgrading Grub with sudo manjaro-downgrade grub to grub 2:2.12.r350.g0e367796-1 provides a temporary solution.

Fixed with grub 2:2.12.r359.g19c698d1-3.

I’ve also pushed the same changes to Testing with grub 2:2.12.r359.g19c698d1-2.0.

I had the same issue (no boot menu). GRUB - ArchWiki paragraph 7.15 suggested:

Also check if GRUB_TIMEOUT_STYLE is set to hidden and set it to menu, 
so that the menu will be shown by default. 
Then regenerate the main configuration file and reboot to check if it worked. 

and that fixed it for me.
