    Original hard drive went bad “ redundancy errors. I had a drive that is good and I installed. The bios sees it and identified it. I was able to put files on it prior to installing drive into laptop. I placed my Windows 10 pro cd in the cd drive. Rebooted and had cd as first boot device. It first searches for media software. When it can’t find it, then it says “insert proper boot media”….No matter what key I press, it just repeats “ insert proper….

    now the original drive prior to going bad had LINUX ZORIN installed. That drive is gone. Now I’m trying to install a 1 lgb drive partitioned into two partitions. C & D
    I have an adapter that I can connect to laptop drives and then USB on my computer. That’s how I tested the 1 gb drive So I know it’s good.

    Why can’t I get an OS onto/ installed?

    Sounds like a format issue. Try installing from a USB. If you already have a Win10 Pro setup - make a repair USB on that. You don't need to check the 'Backup Files to recovery Drive' - that will give you a bootable USB in FAT32 format, which should boot both Legacy or UEFI boot modes. If you then find it has trouble with your newly installed hard drive as the target, use your other device to 'clean' it and just install it uninitialised. Installing using the Repair USB will take care of the disk prep for you which will avoid MBR/GPT mismatch. You can partition it as you want once the OS is installed. Shrink the new Windows volume to what you want and create new in the freshly unallocated space.
