GRUB2 not working after installing xubuntu 14.04

[hector8]

Hi everbody,

I have a vaio laptop and it used to have installed windows 8 and Xubuntu 13.04 in dual boot, everything was working fine.
I decided to update my version of xubuntu 14.04 LTS mainly because the support for 13.04 is finished and LTS version have 3 years of support. What I did was to format the partition where xubuntu 13.04 was installed and install 14.04 in that formated partition. When I restarted my computer willing to start using my new system I got the following message:


error: symbol 'grub_term_highlight_color' not found



and I was not able to enter any OS.
I tried boot-repair from live USB more than two times and it did not fix the problem.
I tried to enter to my computer using super GRUB2 disk, however it does not apperar to work with UEFI active (besides super grub2 disk says it can) I only get the message "no operating system found".
If I boot super grub2 disk with UEFI disabled, super grub2 disk can not detect any OS,I also tried Rescatux distro, however, as of super grub2 disk, rescatux cannot enter when UEFI is active.
I tried boot-repair with the option of "restore EFI backups", after that I was able to boot on windows, but no grub menu appeared. I ran boot-repair again with no improving results
Here is the last Bootinfo report I got:

Do you have any idea of what is happening?
I really appreciate your help,
Best regards,

Did you remove Windows boot entry from UEFI, it is not shown even though your efi partiiton has the Microsoft efi folder.


BootOrder: 0001,2001
Boot0000* EFI USB Device (USB Flash Disk)
Boot0004* EFI USB Device (USB Flash Disk)
Boot0001* ubuntu.


It may be this and Boot-Repair's total uninstall and reinstall of grub from a chroot may work. Or while chroot run the dpkg commands. But Sony's typically do not directly boot Ubuntu anyway.
Ubuntu 14.04 Update breaks grub, resulting in "error: symbol 'grub_term_highlight_color' not found"

You need to chroot & use dpkg-reconfigure grub-pc instead of grub-install directly, so that the system knows that it needs to run grub-install on that drive the next time grub is upgraded.


Sony's all seem to have issues. They only want to boot Windows.
Most users seem to use one of the rename functions. I now do not prefer the rename of bootmgfw.efi that Boot-Repair does as Windows updates will overwrite that.

Systems that only boot Windows from UEFI. Work arounds -Often Sony & HP, maybe others
A: Manually rename files either bootmfg.efi and/or bootx64.efi :

some find this changing this to be shim or grub /EFI/Boot/bootx64.efi
Then booting device or hard drive works also.

B:Boot_Repair rename Windows bootmfg.efi. But cannot boot Windows from UEFI only grub
Always say no until proven that you only can boot Windows entry from UEFI menu.
buggy-kernel detected. Do you want to activate ? yes (if any choice fails, please retry with the other)
To undo & to rename files to their original names, you just need to tick the "Restore EFI backups" option of Boot-Repair.

Any rename either manually or with Boot-Repair will need to be redone after a Windows update as it will restore Windows files.

[B]C: Edit Windows BCD, one Alternative to Boot-Repairs rename of shim.
Some systems work better to register grub/shim from inside Windows - for those that keep resetting Windows as default

bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

D: If Description has to be Windows then change UEFI description.
sudo efibootmgr -c -L "Windows Boot Manager" -l " \EFI\ubuntu\shimx64.efi"

E: Some install rEFInd which seems to be another workaround and has nice boot icons.

One Sony user

The trick was to manually copy the ubuntu Boot directory in place of the \EFI\Boot Directory, and rename shimx64.efi to \EFI\Boot\bootx64.efi (not \EFI\Microsoft\Boot\bootmgfw.efi )
