Windows 10 Home Disk Management problem allocating an unallocated partition

Anonymous

I have an Unallocated partition between two allocated partitions (one is Recovery Partition, other is a Primary partition).

When I try to allocate a new Simple Volume in that unallocated partition, I get an error:

The selected GPT formatted disk contains a partition which is not of type 'PARTITION_BASIC_DATA_GUID', and is both preceded and followed by a partition of type 'PARTITION_BASIC_DATA_GUID'.

What?

That sounds fine.   If any problems type CMD in Start Search, right click Command Prompt to Run as Administrator, then run these Commands to remove an EISA partition which is otherwise locked:

This should add to the Unallocated Space which you can then Create and format in Disk Management for Data.  I would give it letter D which is what is being most used now for Data partitions, but any letter is fine. 

Keep me posted.

    Hi Marty

    My name is Andre Da Costa; an Independent Consultant, Windows Insider MVP and Windows & Devices for IT MVP. I'm here to help you with your problem.

    You right click each of these then click Delete each. It will convert it into unallocated space.

    You can then right click the HP (C:) partition then click Extend then reclaim the unallocated space.

    As long your system (100 MB) partition is not modified, you should be fine.

    In an MBR disk there can only be four Primary partitions before you must convert one to Logical to add additional Logical partitions.

    Since Windows 10 has a built-in reset you don't really need the HP recovery partition which would only restore Windows 8 if it still runs. So you could delete it and create a new Partition in its place spanning the entire unallocated space. This would be easiest.

    Otherwise you could install free Partition Wizard and use its extend feature to extend C partition into the unallocated space which it can do even with the bootable repair recovery partition in the middle, by moving it over. Video demo:

    https://www.partitionwizard.com/help/extend-par...

    Or you can use Partition Wizard to right-click the recovery partition in the middle to add a drive letter, which will enable you to right click it to convert to logical. After this it will allow you to add an adjacent logical data partition in the Unallocated space.

    Let me know which option you prefer and I will write out more detailed steps and provide more tutorials including videos if you need.

    This was originally Windows 8.1 computer, upgraded to Windows 10; subsequently, replaced 320GB drive with 640GB drive.
