Ubuntu – How to install Kubuntu 12.04 amd64 on an Asus N56V notebook

12.04installationuefi

SOLVED

I'm trying to install Kubuntu alogng with the preinstalled Windows 7.

I boot from CD
Create three partititons: / (ext4), swap and a 100MB reserved bios

All installs correctly, but I'm not able to boot Kubuntu

From the bios setup disappeared the option to use legacy bios instead of UEFI (or at least I cannot find it)

I have the option to create a new boot entry, but I don't know what to type in.

What can I do?

Thanks
Mirto

Seems relate to bug 972122 ( https : // bugs.launchpad.net/ubuntu/+source/partman-efi/+bug/972122 )
The message I saw when the EFI boot partition was missing is the same reported in
https : // launchpadlibrarian.net/99750202/EFI-warning.jpg

The bug is marked as fixed-released
What I'm missing?

There is any particular install CD using partman-efi?

I've tried boot-repair using a ubuntu-secure-remix – I updated boot-repair before using it.

I've sent the error output posted at http://paste.ubuntu.com/1088164/ to boot.repair@gmail com

Boot-repair is suggesting other actions and I'll try

At power-on magically the ubuntu boot entry appeared

Boot-repair was the solution

  • Your disk is GPT-type, so you need either an EFI or a BIOS-boot partition. Run Boot-Repair, update it, and click Recommended Repair. Note the URL that will appear. Reboot and check if your problem is solved. Indicate the URL if not.
