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
(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)
