MicroOs - dual-boot - windows 11 does not show in the boot menu

English Install/Boot/Login

I decided to try MicroOs after NixOs. It is installed in dual boot on a laptop with Windows 11. However, windows does not appear in the boot menu. How can I get it to appear?

2

Be sure that Windows does not have Fast Boot turned on. That is the usually reason Windows does not show. Second reason is that the two OS’s do not use the same boot method.

3

Fastboot is off and both of them are EFI. Still, windows is not showing… Is it possible to use dual boot with microos ?

4

“which” flavor of MicroOS are you running?

5

For Aeon or Kalpa, dual-boot is not a supported configuration.

That isn’t saying that you can’t make it work, but it’s not an intended use, and the developers don’t support it.

MicroOS, SLE Micro, or Leap Micro, I don’t know if it’s a supported configuration or not. I suspect not.

6

Is os-prober installed? Is os-prober enabled?

7

I had the same problem. My solution was to switch the bootmenue in the uefi-setup.

8

Os-Prober shows the windows partition: /dev/nvme0n1p1@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi

9

As of today, I’ve found that this is the only and easiest way to switch from one to the other.

10

And is it enabled for grub2?

grep -Ev '^#|^$' /etc/default/grub
12

It is off
GRUB_DISABLE_OS_PROBER=“true”

I am currently trying Aeon.
I understand that dual-boot is not supported.
I understand that it’s not the intended use, but with no contingencies… there’s no evolution :slight_smile:
It’s a bummer since I imagine that people like me (pretty techy but not too much) could benefit from an immutable system that makes sure I can trust that the base system doesn’t become a mess

14

Did you try to enable it?

Here’s what I did to make it work:
• sudo transactional-update pkg install os-prober
• sudo transactional-update pkg in nano

After reboot
• sudo nano /etc/default/grub
• Change GRUB_DISABLE_OS_PROBER from true to false

After reboot
• sudo transactional-update grub.cfg

Thanks arvidjaar !

Here is a shorter version
• sudo transactional-update pkg in nano

After reboot
• sudo nano /etc/default/grub
• Change GRUB_DISABLE_OS_PROBER from true to false
• sudo transactional-update grub.cfg

Thanks arvidjaar !
