 Posted: Sun Jul 08, 2012 7:22 pm Post subject: Grub2 Question |
 |
|
Can any one explain what is going on with Grub2 on my laptop?
I have several OS's installed. Up until recenly I was running Ubuntu 11.04 and the Grub settings on that controlled the laptop boot process. I then installed Ubuntu 12.04 and that took over the boot configuration. That was fine because I wanted to replace the 11.04 OS with Kubuntu 12.04 which I did. As expected the Kubuntu install took over the boot configuration.
I figured that if I ran the update-grub process back in Ubuntu 12.04 then that would provide the boot configuration but that is not the case. update-grub completes normally in Ubuntu 12.04 but the settings from the Kubuntu installation remain in control.
I'd like the Ubuntu 12.04 installation to control the boot process. How can I achieve that? |

Boot to the system you want to use as the grub "supplier" Ubuntu 12.04, and run | Code: | | sudo grub-install /dev/sda |
assuming sda is the boot device, which it will be if there is only one hard disk.
Your update-grub command just did that; it updated the grub menu in the OS where you ran it; it did not install grub from that OS to the MBR.
