I have recently bought this a new dell xps15 9570 computer. I have partitioned the windows such that there is a partition with ~650GB empty. I have followed the instructions here When I start the installation after asking for a wifi connection the installer claims there is only 4GB space and Ubuntu needs 8GB.

My guess is that it is trying to install on the USB stick for some reason. I tried disabling secureboot, no help there.

Finally I tried changing to AHCI (from RAID on), this made the installer recognize the partition. But on these settings Win will not upload (I tried and it doesn't find the boot). Before I continue with this. Will this be a problem later? If so how do I make the settings such that I can upload each OS that I choose?

Thanks Ran

Running parted -l (while on RAID ) gives

    Model: SanDisk Cruzer
    Disk /dev/sda 4005MB
    Sector Size: (logical/physical) 512B/512B
    Partition table msdos

  • Boot from flashdrive to Live Ubuntu (trying it out). Bring up terminal (r. click in desktop). Run command sudo parted -l and add output to your question. – Paul Benson Dec 11 '18 at 20:29

  • Have you updated UEFI from Dell and if SSD the SSD firmware? Have you turned off Windows fast start up and UEFI fast boot?

  • I updated everything. Again notice that the problem is: On RAID ubuntu can't see the partition, and on AHCI windows can't upload – Ran Itay Dec 11 '18 at 22:42
  • Are correct partition/s sizes shown on AHCI. Is Windows partition now seen? That's really what I wanted parted -lto look at. I don't know that much about RAID setup as I never use it. Why do you want to use that? Is your BIOS set to Legacy or UEFI? – Paul Benson Dec 11 '18 at 23:12
  • well I don't but that was the manufacture settings, I actually want to change that and this is the problem I have that now Win is not booting – Ran Itay Dec 11 '18 at 23:42

If you are not bound with limited resources or budget then i suggest better keep additional hard drive and install ubuntu on that secondary drive. Since ubuntu will also create 3+ partitions for internal purpose and windows already occupying 2+ (most probably 3 in your case of branded pc), it may cause drive corruption or lost either os boot sector data (I am not expert but i have faced this many times). Having second os on separate drive will reduce risk of losing data of both os together.

    This is the 4th computer I am dual booting, I don't think this is a good solution for me. But thanks – Ran Itay Dec 11 '18 at 20:44
