    It doesn't matter how you get a screenshot of the 250GB SSD. We just need to see it.

    Big mess on your 2T drive
    Both recovery partitions are empty (100% free).
    The EFI partition is empty (100% free). It seems to be a EFI-GPT but it's missing the boot manager.
    On Disk Manager - View - Top - Disk List
    Take a screen shot and post it here. Better if you have both drives attached.


    Why didn't you cloned the 250G drive into the 2T drive adjusting the C: partition to the new size?
    It's simple, easy and fast.

    Partitions marked as system or hidden, such as EFI System Partitions and Recovery Partitions will always show 100% free space in disk management. It does not mean they are empty. It only means the files and folders on those drives are marked as hidden and system files and folders. That is normal Windows behavior. For example, my EFI system partition shows 100% free in disk management, yet it has all the required boot files in it:

    I did try that option at first, bit do you notice that little small partition at the back of 513MB? That little bugger sits just after your "C" partition. When you clone the 2TB drive look just like the 250. But our big brother Microsoft say" You can only grow or extend the partition if it is the last partition on the disk." And removing the little 513 portion is not a option. You will only get the option of "Help" if you right click on that partition. No other option is available.

    Hi ZBook
    I would not like to go this route. What additional information will this application provide that is not already there? I normally have a resistance to downloaded applications and I will rather skip this step. If this is out of the normal faults, I will try and solve this with help from other sources. I all else fail, I will then re-install the whole lot again. But I was hoping for a quick fix to try and avoid the headache. Thank you for the suggestion but for me, this is a no go.
    Regards

    Were you wondering about the script that was created by a TF member, minitool, or both?

    They display diagnostic information.

    They are free.

    So both drives are set up for UEFI booting. I would recommend clearing your CMOS settings and letting the BIOS rediscover the drives. Some motherboards have a bios reset jumper (with the computer turned off, you move the jumper to the pins to clear the CMOS, then back to the normal pins). Some have bios reset buttons. You can also look for the coin size battery on the motherboard. Unplug the power supply, remove the battery, press and hold power button for a few seconds to bleed any residual charge in capacitors. Re-install the battery.

    Dear All
    Thank you for the support and suggestions thus far. I have decided to bit the proverbial bullet and to save myself a lot of headaches. I have as we say in the "old" days, "Format c: /s" and start all over again. This time success. System boot, Windows Boot Manager is back in the BIOS and I can actually select it.

    Once more, thankyou for all your help.
    Kind Regards
    MIMedical.
