    18.04 Install | disks not recognized for install

    Problem: When doing a clean install of 18.04 via a Live USB on a Dell Latitude (which previously had Win7), no disk (volume) is recognized other than the USB itself. During Ubuntu install the error message displayed is: "You need at least 8,6 GB disk space to install Ubuntu. This computer only has 7.8 GB." (the latter refers to the 8 GB volume of the USB).
    Which steps have been taken thusfar:
    #1 Using Grub, running <grub>ls results in the following disks detected: (memdisk) (hd0) (hd1) (hd1, apple2), (hd1, apple 1), (hd1, msdos2). Running <grub> ls (hd0) indicates " no known file system is detected for" hd0. Running <grub>ls (hd1) indicates "filesystem type iso 9660 - label ubuntu 18.04.3 LTS amd64". In other words, the second hard drive hd1 already contains the ISO image of 18.04 but is not recognized.
    #2. Using Gparted does not result in any other detectable drive other than the USB containing Gparted.
    Question: how to ensure both drives of the laptop are recognized for Ubuntu 18.04 install ? The aim is a clean install of Ubuntu. No dual boot alongside Win 7, which has already been removed.

    Any feed back and help is much appreciated, best Alex

    Sounds a bit like you're still on the live image.
    When the live image completes, you'll have a graphics desktop with the icon "Install Ubuntu". You need to execute this, then your disk will be formatted to ext4.

    Thanks. I can run Ubuntu via the USB, but install is not possible as the 125 GB hard drive is simply not recognized. The solution is possibly in (a) tweaking BIOS and/or repartitioning or (b) re-formatting the drive. Any suggestions are much appreciated.

    BIOS settings should be checked. ACPI, SATA, etc. What disk models and motherboard are involved?

    Thank you. Laptop is a Dell Latitude E 6420 (built 2012). Memory: 4MB, DDR3 SRAM. BIOS is A16 revision. BIOS indicates the following:
    (x denotes 'box ticked / on' / 0 denotes 'box unticked / off')
    > Boot Sequence:
    x Disk
    x Internal HDD (IRRT)
    x USB
    x CD
    x Onboard NIC
    > Boot List Options
    x Legacy
    0 Uefi
    > Sata Operation
    0 Disabled
    0 ATA
    0 AHCI
    x RAID on
    > Drives
    x SATA-0
    x SATA-1
    x SATA-4
    x SATA-5

    Any suggestions tweaking BIOS / drives to ensure Ubuntu recognizes the 125 GB hard disk for install would be much appreciated.

    I would check if you have updates to UEFI.
    Windows started requiring UEFI in 2012, and early UEFI implementations often needed updates.

    Newer Dell need drives changed from Intel RST/RAID to AHCI, not sure about older Dells. Is little x mean you have RAID.
    If true RAID with two identical drives, do not change settings without major full backups. Best to have backups anyway.
