    Installation problem

    Dear All,

    Failed to install ubuntu 18.04.3 or 19.10 to Lenovo Yoga S740 laptop.
    Problem is that when I try to install Ubuntu it does not see the hard drive doing ubuntu installation using usb stick.

    With 18.04.3 usb installation, after selection of keyboard, language and updates, the problem is with the screen has top left: "Installation type", upper box is empty, lower has /dev/sda
    When clicking install now, it complains about "No root filesystem is defined"
    Pressing "+" crashes the installer.

    I tried various boot-option combinations with no success.

    Is the laptop just too new?

    Sorry for my previous post, I did not know it was prohibited to ask people who know answer to my question.

    Terveisin, Markus

    Dear Qlli,
    Could you rename this thread to something a bit more informative, I did not manage that.

    Re: Installation problem

    Problem is that when I try to install Ubuntu it does not see the hard drive doing ubuntu installation using usb stick.
    Which means the drive is new, is unformatted and has no operating system on it, is that correct? If not, you need to post that information.

    On the Installation Type screen, you need to set the mount point for root which is the " / " forward slash symbol. That is why you get the error "No root filesystem is defined". The link below is a tutorial on installing Ubuntu and about half way down the page, there are several images showing this option when you have the "Create partition" window.

    Re: Installation problem

    Sorry,
    It has windows 10 which is working fine.
    I'd like to make it dual boot (or just ubuntu if that's too hard).

    Re: Installation problem

    Many, even new, need UEFI update & SSD firmware update.
    You need to turn off bitlocker & Windows fast start up.
    In UEFI you may want to turn off UEFI Secure boot, and need to change to AHCI for drives. If dual booting with Windows you need to add AHCI drivers first or Windows will not boot with AHCI setting.

    You probably need the newest version of Ubuntu to have latest kernel & drivers.
    If willing to experiment, you can try the 20.04 which will not be released until April 2020, but is getting daily updates and has even newer kernel. You should plan on re-install (but do not have to) as it will have a lot of updates before April and log files & history will be larger than normal. Note that it may also have short term breakage as some update may not work. I have it installed but use 18.04LTS and only use LTS versions as main working install.

    Re: Installation problem

    Dear Oldfred,

    I'm very willing to try out things to settle this problem, it is first time since 90's I have failed to install linux...

    >Many, even new, need UEFI update & SSD firmware update.
    Not done. I try to google this...
    >In UEFI you may want to turn off UEFI Secure boot,
    Done earlier.
    > and need to change to AHCI for drives. If dual booting with Windows you need to add AHCI drivers first or >Windows will not boot with AHCI setting.
    Done earlier so that AHCI was set on , machine did not work at all, so took windows back with a backup-usb, and now it has AHCI. Did not update any AHCI drivers, but maybe windows was able to figure that out.

    Additionally I changed something to legacy, can't remember what it was..

    So please give some guidance how to proceed, where to get 20.04 for instance...

    terveisin, Markus

    Re: Installation problem

    See if version here is any newer than the one you have. Says 13 Nov 2019
    https://pcsupport.lenovo.com/us/en/p...me=BIOS%2FUEFI

    Do not turn on any Legacy settings. That is the old BIOS/CSM/Legacy. And all new Windows pre-installed are UEFI. And you want Ubuntu installed in UEFI boot mode, also.
    CSM - UEFI Compatibility Support Module (CSM), which emulates a BIOS mode, only available with secure boot off.

    If interested in 20.04.
    http://cdimage.ubuntu.com/ubuntu/daily-live/current/
    or which will start download.
    http://cdimage.ubuntu.com/ubuntu/dai...ktop-amd64.iso

    But I have not done a full download for a while. I use zsync which compares .iso file with online file and only downloads differences. When changing, for example from 19.10 to 20.04, I make a copy of 19.10's ISO and rename to 20.04's ISO. Daily download file name will be different than final release. But when I zsync daily from last day or two before release, it is 100% the same.

    If you rename 19.04 iso, and are in the folder with the ISO.

    Re: Installation problem

    Did you update UEFI and SSD firmware as suggested above?
    Did you verify that fastboot and anything related to hibernation in the windows power settings were turned off immediately prior to your attempt to install Ubuntu? Windows turns them back on with some of its updates. It does not ask if you want them on. It does not inform you they will be turned on. THese are the primary reasons you do not see windows partitions in the Installation type window of Ubuntu. Did you get to the point where you select a partition to use or unallocated space and select a mount point for the / (root filesystem) as shown in the link I posted earlier?
