Problem with Lenovo Yoga 900 ISK2 and Linux.

Hi there,

This isn't really related to this topic, but I wondered if I might have a moment of your time to discuss an issue with not being able to install Linux distributions to the Lenovo Yoga 900 ISK2 model Ultrabooks.

The BIOS seems to be locked in some sort of weird RAID mode, and Linux installers can't see the SSD. Lenovo removed the ability to change to AHCI mode deliberately. Thus far, the only way anyone managed to install Linux on it was to mod the BIOS to restore the option and then flash the new BIOS in with an external flasher to evade the signature check. After doing this, he reports that he is able to install Linux on that particular laptop.

I was wondering if maybe there would be a workaround.

The forum topic on this is here:

If you could look into this, I would be extremely grateful.
