    Disk Partition Question After Removing Dual Boot


    I have a desktop PC that was originally Win 7. Back in January, I installed Win 10 in a dual boot configuration.

    All has been fine with Win 10 so I am ready to remove the dual boot (Win 7) OS. I've read the tutorial on removing it here: How to Remove and Uninstall Windows 7, 8, or 10 from Dual Boot PC

    I'm just looking for a little guidance on how to re-partition the Win 10 (C:) drive so I don't mess up and cause a problem.

    Here is the current configuration:

    There is only 1 physical disk - Disk 0. It is a Samsung 1TB 860 Pro SSD.

    I want to do two things:

    1) Delete the Win 7 partition (K:) and turn it into unallocated space so I can add it to the Win 10 partition (C:)

    2) Delete the Lenovo_Recovery partition (Q:) and turn it into unallocated space so I can add it to the Win 10 partition (C:)
    (The recovery partition is for Win 7 from the factory when I bought the system in 2014 and is now useless) Also, note that the recovery partition is a logical drive. I'm not sure if that makes any difference.

    I use Macrium Reflect regularly and will create a full disk image before making any of these changes.

    I have AOMEI Partition Assistant on a bootable USB flash drive. Can I use it to delete the 2 volumes and then extend the Win 10 (C:) partition with the two chunks of unallocated space, or is there a better way? Will there be additional problems since the two chunks of unallocated space will be on each side of the Win 10 (C:) partition?

    Thanks for any guidance or suggestions.

    I recommend MiniTool Partition Wizard Free:
    Best Free Partition Manager for Windows | MiniTool Partition Wizard Free

    You can delete the Lenovo-Recovery and Windows 7 partitions. Also, you SYSTEM_DRV partition has almost 1 GB of free space in it, you might consider shrinking it some. Then you can expand the C: Windows 10 partition to fill all the empty space. Or - you can leave empty space at the "end" of the drive, and create a data partition there.

    Note: when you resize the Windows 10 partition by running any Windows partitioning program from within your standard Windows installation (not booting from a USB flash drive), the program will have to reboot the computer and do that resizing operation at boot time. It's kind of scary to see it do it, but it's normal.

    The MBR system partition displayed 1.4 GB.
    On a clean install this would be approximately 500 MB.
    This would free 900 MB.

    Another option to consider is whether you want to remain with MBR or move to GPT partitioning.

    With a relatively new installation with 81% free space you can clean install too.

    Can the MiniTool Partition Wizard be installed on a bootable flash drive? There's not much user help info on their website that I could find, unless I just missed it. Tutorials or how-to's would be nice.

    UPDATE: Looks like the answer to my question is "no" with the free version. The builder is included with the paid version. I may stick with the AOMEI Partition Assistant that I have on a bootable USB flash drive.

    You could use Kyhi's Windows 10 Recovery Tools - Bootable Rescue Disk

    Mnitool Partition Wizard is one of the tools on the drive

    Done


    Thanks for the tips! I did a full disk image backup with Macrium Reflect this morning. Then I used the AOMEI Partition Assistant I had on a bootable USB flash drive and re-partitioned the SSD with no problem. I also shrunk the MBR system partition. I formatted the old Win 7 recovery partition and decided to leave it there for misc data.

    All is working well.

    Here's the final configuration:
