Comment 9 for bug 1242417

I tested the new packages- https://launchpad.net/~rohangarg/+archive/experimental

I Completely wiped drive and UEFI entries first - I :-

- installed kubuntu
- installed efibootmng
- mounted new root in /mnt/sda3
- mount /dev/sda1 in /mnt/sda3/boot/efi
- mount /proc, /dev, /sys in /mnt/sda3/[dev/sys/proc[
- chrooted

[in side chroot]
- added PPA for new grub
- did a apt-get update/dist-upgrade
- deleted old UEFI entry via efibootmng
- grub-update (no new uefi entry appeared)
- grub-install -> new entry appeared.

[rebooted]

*** OS Boots *** !

But... - as well as creating a kubuntu menu entry in creates an 'ubuntu' one also -this also boots kubuntu - but you cannot get rid of the entry .... i.e if you delete the entry using efibootmng it will come back on reboot ? if you delete the kubuntu one that doesn't come back automatically.

Don't know if relevant but /boot/efi/EFI/ubuntu also exists now..

I have found even if I remove /boot/efi/EFI/kubuntu the system still boots as long as /boot/efi/EFI/ubuntu exists....

I cannot get rid of the 'ubuntu' UEFI entry - I have used efibootmng and bcfg and after reboot it comes back - the only way to remove it is - remove entry and delete /boot/efi/EFI/ubuntu - that means kubuntu is unbootable though.
