Ubuntu

no grub screen

Asked by Ronald

No grub screen after update to 12.04 LTS. When booting i get a black screen with a flooting panel tha says something about video frecrency. I found that if i hit the down button once and enter i get the log in screen. I boots to 12.04 and works fine. If i hold the down button down at bootup it will boot to the windows OS. Up dated from 10.04 LTS to 12.04 LTS.

You may need to set the res in /etc/default/grub

Try to use boot-repair and see if this fixes your problem

boot-repair instructions : https://help.ubuntu.com/community/Boot-Repair#A2nd_option_:_install_Boot-Repair_in_Ubuntu

Focus on second option (page I gave).

Tryed boot repair. Clicked on recommended repair. It run and run and didn't stop. Had too turn computer off. How long should it take.

Its nothing to do with boot repair. The res just needs setting so that it shows as the monitor / display is not doing what it should so grub needs configuring. Did you use the web to find guides?

I used on one of then to change resolution. Change resolution in grub. Then run update-grub. It run for a long time and i rebooted and same problem. Checked resolution in grub and it changed it to the setting put in. After reboot still no grub screen. Is there a way to rerun the upgrade to 12.04 again. I run the updates that came up and it has been running for a long time also( an hour +). It seems like the whole upgrade didn't run right.

If the upgrade progress failed or you think that didn't ran right , you can re-install Ubuntu 12.04 .

It is about 20 to 30 minutes procedure.

You can download the iso image from here
http://releases.ubuntu.com/precise/

and create a bootable CD/DVD or USB-stick.

Boot from there and re-install Ubuntu to the same location where it is now.

Do not forget to BACKUP your important (personal) files BEFORE the installation .. for any case.
