====== Install Ubuntu 21.04 ======
to maintain Windows installed:
	1. disable BitLocker (Impostazioni->Aggiornamenti Sicurezza->Crittografia->Disabilità)
	2. disable Secure Boot (from BIOS)
	3. re-order the booting devices (from BIOS)
	3. use a USB to boot the ubuntu 21.04

==== Possible issues ====
**Backlight / nomodeset** 
 
In case you are using a laptop with intel i7 gen. 11th and iRIS XE graphics you should use kernel **5.11.0-16-generic**
A possible solution is to add the following lines in **/etc/default/grub**:

	GRUB_DEFAULT=saved
	GRUB_SAVEDEFAULT=true

Then reboot the system, select //Opzioni avanzate per Ubuntu// and //Ubuntu, con Linux 5.11.0-16-generic//. You must do that only once to save your preferences. 

**Wi-fi**  

To install the correct drive you should follow these command (and might read the discussion at this [link](https://forum.ubuntu-it.org/viewtopic.php?t=637471)):
	1. Make sure you have a proper build environment and dkms installed.
	2. sudo su
	3. apt install bc module-assistant build-essential dkms
	4. m-a prepare
	5. apt install rtl8821ce-dkms
