I bought myself a new Laptop, the ASUS GL771JW with 250 GB M2 SSD drive and a 1 TB HDD.

Now I'd like to install Ubuntu 15.10 on it, but I get errors.

I downloaded the amd64 Ubuntu ISO and put it on a USB stick using sudo dd if=/home/myuser/ubuntu-15.10-desktop-amd64.iso of=/dev/sdd. Then I load the Live OS with Unity on it and start GParted, right away getting the error message:

Libparted Warning

The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes.

Cancel / Ignore

If I hit Cancel GParted only shows an unallocated 7.41 GB drive on /dev/sda which is my USB stick. I can as well select /dev/sdb which is my 1 TB HDD drive, but I cannot select my 250 GB M2 SSD drive.

If I hit Ignore GParted shows 4 partitions on a 29.65 GB drive on /dev/sda:

  • /dev/sda1, FS unknown, size 4 KB
  • unallocated, FS unallocated, size 1.09 GB
  • /dev/sda2, FS fat16, size 2.22 MB
  • unallocated, FS unallocated, size 28.56 GB

I have no idea where it gets that from and I miss the rest of the 250 GB drive.

Does anyone know that problem? I tried to find some useful settings within the ASUS BIOS / UEFI-BIOS, but wasn't too successful with it. What must I do to install Ubuntu on my laptop?

I had the same trouble with an NVMe disk. That technology is quite recent and the old version of GParted in Ubuntu repo couldn't see my SSD. I resolved creating a GParted live USB with the latest version of the software.

    +1 Good answer but for a more Ubuntu based solution you could add this download to your answer, it has gparted .debs for a newer version that should work too ubuntuupdates.org/package/getdeb_apps/wily/apps/getdeb/gparted

  • Thanx, I forgot. 0.24 at your link should be the first release that included NVMe support.

  • Ok, I tried it with GParted version 0.24 as a Live Disk from gparted.org. Unfortunately it doesn't work. GParted still does not recognise my SSD drive (SD7SB3Q256G1002). Are SSDs not yet fully supported in Ubuntu? Isn't it possible to install Ubuntu on it?

  • Full support to NVMe was added in GParted 0.24.0-2. The version that did the trick for me just a week ago was 0.25. I suggest to retry with that version. Anyway launching the installation of Ubuntu you should be able to partition your SSD with Ubuntu disks partitioner.
