Busenlabs 32bits on external SSD usb

Crap0 · 2017-12-24 22:14:09

Hello

Excuse my english, I use google translate to translate this french post.
(further the original post in French)

I would like to install Busenlabs Deuterium 32bits on a ssd removable usb 3 disk.
I would like this Busenlabs to be bootable on as many computers as possible.
I created two partitions before starting:
1- to install Busenlabs
2- for my other data

I start on a bootable USB key with a usb-live Busenlabs.

During the installation, I am asked if I want to force UEFI use.
I answer at first "no, do not force in UEFI mode"

I am doing a manual installation.
I do not put a swap.
and I created only one / home partition in ext4, on the partition chosen to install Busenlabs.

I do not have an internal hard disk on the computer I work with and do this installation.

After installation, I am asked or I want to install my bootloader.
I install it on my SSD.

The installation, gives nothing ... My SSD with Busenlabs installed, does not start. The computer does not find any bones.
I use a Macbook Pro and to start on an external media, you have to press the key "c" at startup.

Following this failure:

With gParted:
I created a new partition table on my SSD in msdos.
I created a partition in FAT32 of 250Mo at the very beginning of my SSD, for a future EFI.
I created my two partition for Busenlabs and my other data again.

I redo a manual installation.
On my score of 250Mo, I put the ESP.
And my / home on the chosen partition.

The installation ends and still no result of boot on my SSD after rebbot.

Could you help me please.
Thank you

J'ai créer deux partition avant de commencer:

2- pour mes données autres

Je démarre sur une clé usb bootable avec un live de Busenlabs.

Lors de l'installation, on me demande si je veux forcer l'utilisation UEFI.
Je reponds dans un premier temps "non, ne pas forcer en mode UEFI"

Je fais une installation manuel.
Je ne met pas de swap.
et je ne cré qu'une partition /home en ext4, sur la partition choisie pour installer Busenlabs.

Je n'ai pas de disque dure interne sur l'ordinateur avec lequel je travaille et fait cette installation.

Après l'installation, on me demande ou je souhaites installer mon bootloader.
Je l'installe sur mon SSD.

L'installation, ne donne rien... Mon SSD avec Busenlabs installé, ne démarre pas. L'ordinateur ne trouve aucun os.
J'utilise un Macbook Pro et pour démaré sur un média externe, il faut enfoncé le touche "c" au démarage.

Suite a cette echec:

Avec gParted:
Je cré une nouvel table de partition sur mon SSD en msdos.
Je cré une partition en FAT32 de 250Mo en tout debut de mon SSD, pour un futur EFI.
je cré à nouveau mes deux partition pour Busenlabs et mes autres données.

Je refais une installation manuel.
Sur ma partition de 250Mo, je met le ESP.
Et mon /home sur la partition choisie.

L'installation se termine et toujours aucun résulta de démarrage sur mon SSD apres rebbot.

First of all: Debian has different versions of GRUB for UEFI & non-UEFI systems and it is not possible to have them both installed at the same time.

Your Macbook should be able to boot the system as you first installed it (non-UEFI with an ms-dos partition table) as long as you disable UEFI mode and enable CSM or "Legacy" mode in the firmware ("BIOS") options.

In respect of UEFI booting:

I created a partition in FAT32 of 250Mo at the very beginning of my SSD, for a future EFI

The EFI system partition needs to have a special GUID partition code applied so that the motherboard can identify it.

In gparted this code is set by applying the "boot,esp" flags, did you do that?

It may be possible to create a drive that boots in both UEFI and non-UEFI mode but not all motherboards will support both methods, unfortunately.

thank you.

no, I did not do it ...

I just redo everything with a first score of 200Mio fat 32 for the future EFI and I put the flag "boot" and "esp".

Will try.

But I redid a partition table "ms-dos" ...

Should I try with a partition table "gpt"?

For a UEFI system, a GUID partition table is recommended and is more likely to work than an ms-dos table.

For a non-UEFI system the opposite applies and an ms-dos partition table is the best choice; also, if you use a GPT disk then you will need a special BIOS boot partition for GRUB to work.

I have an SSD in my latop with a GUID table and a BIOS boot partition that uses GRUB for non-UEFI booting and systemd-boot for UEFI but that won't work with every motherboard.
