Ubuntu – No installation type when Dualboot Ubuntu 16.04 and Windows 10 (SSD & UEFI)

dual-bootpartitioninguefi

I know this topic is all over the web, but none of the solution I've found solved my problem.

I want to install ubuntu 16.04 LTS in dualboot mode onto a new computer (Lenovo Yoga 910, intel i7-7500u, UEFI and SSD) along side Windows 10.

I configure a USB drive to a .iso with the 64bit version of Ubuntu 16.04 LTS.
I disabled fastboot, my ssd drive is in "basic mode" and I shrunk the Windows volume. There is now, 6 different parts in my SSD :

  • Partition of EFI system (260mo)

  • Windows (C:) 96.95 Go (NTFS)

  • Data (E:) which I created to store data that will be both used in Windows and Ubuntu 254 Go (NTFs)

  • Lenovo (D:) 25 Go (i don't know what it s for but it was there at the beginning)

  • A back up of 1000mO

  • And finally a non allocated space of 97 Go that I dedicate to the (hopefully) coming Ubuntu environment.

I then reboot holding f12 to boot from the USB key, I then choose the option "install ubuntu".

1) I choose English then hit Continue

2) I don't connect to wi-fi

3) I don't tick anything in preparing to install ubuntu.

And then I would expect to get the window :
enter image description here

But I don't. I directly get to the second window "Installation type" with the list of device on which I could install ubuntu. And there I only got one device named /dev/sda (which by the way is the same name as the "device for boot loader installation" : /dev/sda Kingston DT, which I found weird).
I expected to see the 6 disk partitions I mentioned earlier.

I read the answer : How can I dual-boot Windows 10 and Ubuntu on a UEFI HP notebook?
But it doesn't apply to me.
As well as this tuto : http://linuxbsdos.com/2013/03/12/dual-boot-windows-8-and-ubuntu-12-04-in-uefi-mode/

It is now a day I am on this question… Does anyone know what can I do from there ?
Thanks a lot.

    The /dev/sda device you're seeing sounds like your USB flash drive, on which the Ubuntu installer itself resides. The symptoms you're reporting are usually the result of Ubuntu being unable to read your hard disk, which in turn usually means that the disk type or disk controller is not supported by the kernel you're using. If I'm right, there are several options for how to proceed:

    • Since Ubuntu 16.04 and 16.04.1 use an older kernel, you may need to upgrade to a newer kernel by using Ubuntu 16.04.2, Ubuntu 16.10, or even a pre-release version of Ubuntu 17.04.
    • If none of these versions work, then you could try another distribution (something unrelated to Ubuntu -- Fedora, OpenSUSE, or Arch might work; but don't bother with the likes of Mint or ElementaryOS, since they're based on Ubuntu).
    • Another option is to install Ubuntu on an external USB drive. You'd need to use this drive for your shared NTFS partition, too.
    • You could run Ubuntu in a virtual machine (VirtualBox, VMware, etc.) running under Windows.
    • If the computer is new enough, you could return it to the store for a refund and get something else; or even if that's not an option, you could sell it and buy something else. In either of these cases, you should obviously be more cautious about compatibility. You might want to consult the Ubuntu certified hardware page to be sure you get something that works with Ubuntu.
