Ubuntu 20.04 LTS asks to restart and switch off the intel RST

[Filipedls]

Describe the bug
During the installation of Ubuntu I had to restart due to the Intel RST hdd driver.

To Reproduce
Followed exactly the same steps in the tutorial, but for a Lenovo Y720

Expected behavior
Got the Ubuntu installation screen asking to restart and switch off the intel RST.

Screenshots
If applicable, add screenshots to help explain your problem.

System Info (please complete the following information):

• Ubuntu 20.04LTS
• Lenovo Y720

**Solution:
in UEFI/BIOS, switch SATA controller from Intel RST Premium to AHCI

RST isn't very well supported, and is generally only enabled on machines with a hard drive and a cache ssd, or in the case of newer models, Optane.

I can add some additional information to the troubleshooting steps. I cannot grab screenshots though because I don't think my Y530 is configured in a way that allows iRST.

I have updated the guide to include this information in the considerations section and the troubleshooting section.

Hey! Thanks, sorry for the late response, but let me know if you want me to take some pictures of the Y720 bios, even though it's not the same PC, this guide was quite useful for me still. I also had to disable some safeboot options in windows, windows doesnt like to boot with a different sata controller. I had to do those steps: https://support.thinkcritical.com/kb/articles/switch-windows-10-from-raid-ide-to-ahci. This is easily avoidable if you install windows with AHCI mode from the start.
