Droidjack 4.0 cracked tongue. My Lenovo Yoga 720 with a 4K screen just arrived. I've booted into the Bios from Windows (power off menu + shift) changed the Raid to AHCI. Rebooted with a USB loaded with Mint Mate 18.2 (Sonya) 64bit. The screen show a few Linux Grub pre-boot options (Grub 2.02 ~beta2-36ubuntu3.7) (why is Grub a Beta version?) but neither regular boot nor compatibility mode work. I always forget how troublesome bringing up a new type of machine can be. I don't care about dual-boot at all.

Could there be trouble with Nvidia and/or the dual graphics mode? From Wikipedia: Known issues Many users have discovered that a Linux operating system cannot be installed on many Yoga models including the 900 ISK2, 900 ISK for business and 710.[21][22] There has been much accusation and rumour in the computer press including unfounded claims that Lenovo have deliberately prevented Linux from being installed.[citation needed]The reason that Linux cannot be installed is that Lenovo have implemented the solid state drive (SSD) on these models in RAID mode rather than the more usual AHCI.

RAID mode requires additional drivers from Intel that are provided with Windows (version 7 and later) but not currently provided with Linux. Intel recommends that all new motherboards using Intel chips should be configured using RAID even for a single disc, since this avoids problems when upgrading an AHCI configuration to multiple RAID drives later. However, this reason alone is pointless on a laptop where a second disc cannot be installed. Intel also recommends that solid state discs be set up in RAID mode as it provides improved performance with their chips.[23] Lenovo have apparently followed this advice and have also removed the ability to change the mode back to AHCI in the UEFI setup utility. Although it is theoretically possible to change the mode to AHCI using a suitably programmed bootable USB stick, it is not wise to attempt it because the affected models check the UEFI configuration at startup and will detect the change and refuse to boot.

This inability to change to AHCI means that without RAID drivers, either in the system itself and on the installation media, Linux cannot be installed. Claims that this was a deliberate act on the part of Lenovo are unfounded and unproven because there in nothing to prevent the Linux community from writing their own RAID drivers.[citation needed] Other products are equally affected. Windows 10 itself cannot be clean installed because the bootable installation media lack the RAID drivers (the installation would have them but it is the installer itself that lacks them). Rescue media built by the 'Backup and Restore' utility cannot restore the backed-up image to the SSD drive because it cannot see it.

Even third-party disc imaging utilities such as Acronis True Image lack RAID drivers in the rescue media which are generally based on a Linux system. The RAID drivers can be injected into the boot image on USB stick rescue media (though not on DVD-based media).
