Troubbleshouter for EFI invalid path

[Poutrathor]

These are the possibility offered by the BIOS/UEFI menu:

Window Boot Manager (P0: Hitachi HTSXXXX) (1)
Ubuntu (P1: Hitachi HTS XXXXXXXX) (2)
idem except P1 replace by P0 (3)
idem except P0 replace by P1 (4)
P2 MATSHITABD-CMD UJ160 (5) my second drive I believe
Enter Setup

(2) = (3) and the three ubuntu have the same HD. Doubt for the Windows one, it should be different will edit next time I go back there.

The order of priority for booting is the same as above except that window come in second position.

Boot-repair does not repair with normal options. I want to try it following the second example of dual boot, the one where the OP wrote a step-by-step process after he succeed.

For the EFI install in the sda1, I am wondering: I am sure to have selected sdb as the device for the bootloader but as mentionned in my previous post I feel like my partition sdb1 which I had planned to be a EFI booting one has failed since it is not similar as the one for Windows; the ubuntu booting files might be the ones installed by my first installation of ubuntu.

I keep reading/trying, Thank you for your support, I feel less alone -_-

BTW I love Chicago (went twice)
have you vote yet?

Have you tried booting with each of the entries?

My wife & went to vote this morning, no lines except if wanting to use the video mode. Then out for breakfast which do only do occasionally.

Standard process is paper with fill-in circles and scanner to read. One advantage of paper is the paper trail & when scanned it will tell you some basic errors like two entries or missing entry and let you fix or accept as is (vote for that candidate will not count).
I go back to the days of arguing over whether the X on a paper ballot was inside the box as required. If outside some argued intention, but rules were inside only. But then they argued over X on the lines of the box. Someone is always unhappy with the results and wants to make waves.

YES!

After a nice sleep, I did it! As far as I see, it is working fine.

Thank you Oldfred for your kind support and advice, I would have not succeed alone!

The all powerful thread, solution for dual boot on double disk:

It is indeed the indexation of the W7 bootloader that is not correct and need to be added as described above. All that I still could do is to remove the wrong entries in the grub2 menu for aesthetics.

still don't believe it! I learn a lot again, thx!

Voting is kinda complex in the USA ^^ and very often waves about cheating. In France we are still paper election so we do not really know if there are frauds

See you!

Good job

Logs indicate you have only used the "Create BootInfo" button of Boot-Repair. Did you try the "Recommended Repair" button? if yes, please could you indicate the URL that appeared?

EDIT: i think this was a bug introduced in the boot-repair3.194~ppa50 package. I fixed it today.

Glad it worked.

Yann's Boot-Repair fixes two standard issues with UEFI installs.

One is where users install in BIOS mode. Boot-Repair will un-install grub-pc and install grub-efi and update fstab so it is correct UEFI install.

The other is the bug in grub2's os-prober that puts in a BIOS/MBR chain load entry to Windows. Boot-Repair will automatically add the correct chain entries back to the efi Windows boot loader.

If you do not want the os-prober you can turn it off so you do not get the old wrong entries, or back on later if you add more systems and want another update.

In /etc/default/grub I added this, change back to false if you want to run it again:

gksudo gedit /etc/default/grub

GRUB_DISABLE_OS_PROBER=true

or turn off executeable bit
sudo chmod a-x /etc/grub.d/30_os-prober

Then run
sudo update-grub
