I have an EFI based laptop with Windows 8 pre-installed. I wanted to install Ubuntu 12.04 in dual boot, started from the Windows boot manager.
I shrinked a Windows partition, booted Ubuntu from a USB and installed it in the empty space (seen then as /dev/sda8
) freed up above. I specifically chose the boot partition to be on the same partition as Ubuntu (/dev/sda8
).
My expectation was that I would reboot to Windows (since the boot loader was expected not to be touched) and then configure the Windows boot loader to look for Ubuntu.
Since I am typing this from Ubuntu you may have guessed that it did not go that way :)
Upon rebooting I have the Ubuntu boot manager
but the Windows Boot Manager
entry unfortunately does not work (the first picture is the left side of the screen, the second one - the right one):
I hope that all the partitions are still there (looks so from gparted):
It looks like from the error that the Linux boot manager does want to load the right partition (/dev/sda2
).
I can use any of the boot managers, whatever works. How can I either recover the Windows boot manager and then configure it to boot the Linux partition, or have Windows boot from the Linux one?
