No the sound and the microphone aren't working unfortunately

Are you using Zorin Lite? 32 or 64 bit?
Also please explain how you made the bootable drive. (app/etc)..
did you check BIOS for "fast boot"?
did you install or are you using "TRY" Zorin?
Please remind me is this dual boot?
( if not then ignore the fast boot being disabled) leave enabled.

64 bit (amd64).
I used USB creator (on Zorin Core) to create a bootable USB for Zorin Lite.
I must have Windows to do that no ? My BIOS is the following : SeaBIOS
I installed it on my primary disk.
I've only that OS on my primary disk but there is another one on an external disk.

I don't know about seabios, i assume it has upto date firmware/drivers for your laptop?

Can you open "alsamixer" in terminal,
Enter F6, then F5
And show results here

Ok have you run a checksum on the download?

if so, then please reinstall restrited extras & ubuntu drivers, from above post
Also before installing Zorin did you run the check configuration, the third option when you startup the install drive?

The checksum seems okay :


I'll try the third option rn

The third option is my BIOS is it normal ?

should look like this.

do you have another usb drive?

1 Like

yes I've another USB drive

OK try the other usb stick.
As it's is the common item being used & you are getting the same problem,, so a diff stick may help,
( being the other stick may have bad segments interfering with the install).

Ok can i ask you to follow this tutorial for chromebooks.

Zorin is based on Ubuntu 20.04

Ok thanks I'll take a look rn

That guide is if I was on ChromeOS but I'm not, I'm on Zorin Lite

I would assume it would be the same no matter the original OS,
this is like secure boot, " * Enabling Chromebook Developer Mode to Access Shell"
Some machines ( very few) need safe/secure boot disabled,
I assume the developers mode enabled will allow/bypass some checks, making install possible? (complete install)
I would also at this point " disable" fast boot,
