The installer can only install a UEFI system if it is booted in UEFI mode.

Our UEFI capable ISO image is here:

https://drive.google.com/file/d/0B7BNzo … sp=sharing

You will only be able to install a UEFI system if you can manage to get that ISO booted with UEFI mode enabled.

I have had success booting that image on two different UEFI laptops, the image has worked for others as well.

Ah!
Thanks for your help. I'll give a try (soon).

Deuterium is a point release of Hydrogen, based on Stable/jessie. The UEFI build is based on Testing/stretch, and is for testing purposes for the next release - Helium (Stable/stretch).
BunsenLabs "Deuterium" point release

NB You have a typo: I assume it should be "stretch_build"?

if=live-image-amd64-170211-strech_build.hydrid.iso

Yes, but for for what I understood it is my only solution (a part converting Hydrogen to UEFI mode or switching to another linux distro). I can't wait for Helium (I like you naming convention by the way!).

And typo corrected.

Well, that is what Professor Honeydew Bunsen has specified!

Don't you mean Doctor Honeydew Bunsen??

^ Or even "Dr Bunsen Honeydew" 8o

Still not detected. This time I booted in UEFI mode, secure boot disabled on my flash disk. While in the installation menu:

$ ls /sys/firmware/
 acpi  dmi  memmap

(no presence of EFI system)

I installed anyway, but now I cannot boot the linux partition while re-booting in UEFI mode (works in Legacy mode).

Hmmm...

From the BunsenLabs system and with the USB stick containing the ISO image plugged in, what is the output of:

sudo parted --list

If you cannot boot the UEFI-capable ISO image then your UEFI firmware is probably defective and does not boot $ESP/EFI/BOOT/BOOT{X64,IA32}.EFI automatically, as it should.

Can you boot a Fedora ISO image in UEFI mode?

Your only alternative is to convert your non-UEFI system, as I have mentioned (and provided links for) several times already in this thread...

Ok, maybe something here (problem with /dev/sdb):

^ Yup, looks like the table is corrupted, that may explain things.

Try:

sudo apt install gdisk
sudo sgdisk --zap-all /dev/sdb

This should clear all traces of the partition table(s), check by running `parted --list` again — if the table is clear then you should be able to transfer the image properly as per https://www.debian.org/CD/faq/#write-usb

cyrf0006 · 2017-04-03 17:17:14

After all, that was the problem... Corrupted USB stick!

This time during the installation, I had the option to boot on "UEFI usb stick", which was not present before (only boot Legacy USB was available). There are other small details to tweak, but I will ask in another post.

Maybe one last thing of interest: If you have BitLocker activated, be prepared to have you key in hand, otherwise you won't be able to boot Windows (key will be asked).

Many thanks!
