This is the reverse question of How to reboot into Windows from Ubuntu?.

I'm using a PC with Windows/Ubuntu dual system. The PC is shared with others, so the default boot system in Grub is set to Windows, and the timeout is 1 second.

In order to switch the running Windows to Ubuntu, I have to reboot the windows and wait at the very short time of grub menu to choose the ubuntu entry. Many times I had missed or forgotten the chance and the system booted to windows again. (so I have to reboot again). Is there a way to directly reboot the windows to Ubuntu? Thanks!

Why don't you raise the grub timeout also! – jwbensley Jan 22 '13 at 14:14

Take a look at: How can I choose which OS grub will reboot me into—before I reboot?

This looks excactly like what you want. Basically it proposes to use grub-reboot.

Thanks for the info. But the answers to that question were all assuming that the OS before rebooting was Linux, which is different from my case: Windows. I've modified the title to be more clear. – whuang Jan 24 '13 at 7:11
ok, well that was not clear to me. sorry. I don't know how grub-reboot works, but I'd suggest you look into that. You propably have to use an ext* driver for windows in order to mount your boot partition, so you can edit grub and imitate grub-reboot behaviour. – JavaJens Jan 24 '13 at 18:12
unfortunately this does not answer the question – d3vid Dec 30 '13 at 8:51
