dd used to write trisquel iso to libreboot x200 to usb
also tried with Etcher, same result

'Detect Disks
Failed to load installer component
Loading libc6-udeb failed for unknown reasons. Aborting.'

I'll try another usb, aside from this, what else can I try?

I format the usb to FAT32, then unmount, then DD
Format to NTFS, unmount DD
Format to FAT32, unmount, Etcher.

What else can I do?

This is a known bug at the moment. You can check the post made a few weeks ago for more details.

The text mode install fails at that stage. It is a problem with Trisquel, not with your system or methods.

If you want to install you can select 'try Trisquel without installing' (the option where it loads the OS for you to have a look / try out) and select install Trisquel via the desktop icon. This has worked for me.

(I did notice after install that the system wouldn't update. I had to go into the software update menu and switch the drop down menu to main server (or something like that - I can remember the exact menu in Trisquel)).

No luck if you want to install using the text mode (e.g. encrypted boot install).

Thanks, got it installed.

I had the default encrypt installation box checked in the GUI install within the live encironment. Do you know if the entire OS and storage is encrypted, and which cipher is used?

For example with text install I can encrypt full disk with serpent 256 bit.

I did try trisquel without installing, and left the encrypt install box on, Im curious what cipher it uses and if that encrypts the entire disk (It encrypted 136 gigs of my 150 gig HDD so i think it does).

ty! All working tho =) just curious as to the cipher. (128 bit AES, etc)

I don't know what the installer uses as a default, sorry.

Using the installer you've essentially done the same as for most GNU/Linux distro installations. Same as if you installed Debian on a random laptop and selected encrypted installation in the GUI.

The libreboot installation guide is slightly unique:

------------------------------------------------------------------------------------------------------------
"On most systems, /boot (the folder that contains all the files needed for your operating system to boot) has to be on its own partition, and left unencrypted (while the other partitions are encrypted); this is so that GRUB (and therefore the kernel) can be loaded and executed, since traditional firmware can’t open a LUKS volume.

However, with Libreboot, GRUB is already included directly (as a payload), so even /boot can be encrypted; this protects /boot from tampering by someone with physical access to the machine."
------------------------------------------------------------------------------------------------------------

So, the Libreboot guide is a way to perform an encryption installation which includes /boot. It's a key selling point of Libreboot that you can perform this extra step. Not that it is necessarily required (just as a 'normal' encrypted install is always the best option).

Hope that helps.

P.S. I'm not an expert at all, so consider that my info may be incorrect / incomplete.
