Unable to install Kubuntu 24.04 LTS on a Dell laptop 512 G hard drive - insufficient space?

[jleach]

I am trying to install Kubuntu 24.04 LTS on a Windows7 Dell Precision 5510 with a 512 GB hard drive. I boot the 24.04 LTS iso image on a flash drive, then select “Try or Install Kubuntu”. When I get to the first screen, I select Install Kubuntu which always fails saying “There is not enough disk space. At least 8 GiB is required”. I want to repartition the entire disk manually for Kubuntu but cannot get to that step. I have successfully done this many times on an old Dell Latitudes with no problems and others seem to be able to install on the Dell Precisions. Suggestions appreciated. I am completely out of ideas.

The partitioning of the disk drive is as follows. Partition 2 seems to be the problem.
partition 1: 500 MB Healthy EFI System Partition
partition 2: 917 MB Healthy Primary Partition (NTFS) – marged from recovery and oem partitions
partition 3: 475.55 GB Windows7 (NTFS)

Can anyone help?

Windows 'reserves' the entire disk it is installed on, even if it isn't occupying the entire disk. You must shrink the Windows Volume you want to use to install Linux onto from Windows. See https://learn.microsoft.com/en-us/wi...a-basic-volume

Is your partition #3 too full? You might not have enough free space.
