I tried with it reenabled but it didn't work.

The computer doesn't have a Legacy mode. All the OS are installed under the

Nothing important. Windows.

I installed from a USB stick. Now the Debian is in my disk

I used Win32DiskImager

The PCI. I have a GPU so maybe that's why it doesn't load the desktop.

OK - So you now have a working Windows system and a part installed Debian.
I would suggest that you install the firmware-linux-nonfree and
firmware-misc-nonfree packages to get firmware onto the machine.

The first time I used an image without non-free firmware. It nothing worked and I had the same problem. With this version with firmware it gives no errors, but the OS doesn't begin (as I said the GRUB works and the rescue mode gives no errors. The only thing that keeps wrong is the pci, that shows unknown messages... I will try with the packages you've said an retry.

Other question... How do I write to the ext4 filesystem without a GNU system? I have some .deb packages I want to install (downloaded from the AMD webpage) and I don't know to mount it in the rescue-mode (I try with the `sudo mount /dev/sda1` but it was unable to mount it. I tried with `umount` too.

What GPU do you have?

It's an AMD Radeon Vega Graphics

In the install, are you sure that you selected a desktop. If you are not sure, then, as root, execute the command tasksel and see which desktop is selected.

I think GNOME was correctly installed... I will check as you say.

All the very best,

Thanks for your answer :)

Happy hacking!
