GRUB2: Why is OS-Prober now disabled by default?

[anon89812132]

Hello,

a quick search would have revealed quite a few topics about it

What was the logic to disable os-prober?

Check here Grub2 | Secure Boot Bypass and other issues - Update highly recommended

Os-prober does not work as it must

You can try to start Manjaro with /etc/grub.d/40_custom and commenting out os-prober. This will start the bootloader of Manjaro afaik and not manjaro entry direct. If openSuse or Manjaro update kernels, otherwise there will be much work to repair… EDIT: look for: “chainloader” (Can't boot into windows after updating)

Windows 10 has disappeared from GRUB menu

Hi @MattG, As per the latest update announcement: Grub got some needed security updates . Note that os-prober is now disabled by default for security reasons: broken patch ; fixed patch . More infos about it here . To restore the old behavior, open a terminal and issue sudo echo GRUB_DISABLE_OS_PROBER=false >> /etc/default/grub && sudo update-grub
