[Bug 428443] Re: There should be a way to hide the menu in os-prober

[Ma Xiaojun]

Hi, all.

I'm using Ubuntu 12.04 and Mac OS X dual-boot.
For my case, the GRUB cannot boot my OS X correctly, so I also want to hide OS X entries.

It turns out that the hidding steps are quite straightforward:
sudo chmod -x /etc/grub.d/30_os-prober
sudo update-grub

Title:
  There should be a way to hide the menu in os-prober

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  In some cases, it might be desirable to hide the boot menu even if
  other OS are discovered. For instance in Wubi case, the grub menu is
  shown after the windows one, so it becomes confusing.

  GRUB_HIDDEN_TIMEOUT could be used to specify that the menu has to be
  hidden or possibly some other variable could be used to that effect.
