Now I am stuck as to what to do. I have also found from creating an Ubuntu bootable USB that I have the same issue on a micro sd card which is in it's original USB holder. You can see disk 3 is the subect of this post, disk 4 is the micro SD card in a USB caddy.Code:DISKPART> list disk Disk ### Status Size Free Dyn Gpt -------- ------------- ------- ------- --- --- Disk 0 Online 476 GB 2048 KB Disk 1 Online 931 GB 0 B Disk 2 Online 1863 GB 0 B Disk 3 Online 58 GB 0 B Disk 4 Online 15 GB 5120 KB DISKPART> select disk 3 Disk 3 is now the selected disk.

What can I do now?
The second partition you are trying to create on the flash drive there as well as any other usb media will not be available in Windows. I know that only too well from having made up Live Data Recovery sticks with Linux on the first of two as well as the second where Windows will only see the first Fat or NTFS volume created. Funny how the other can plainly see every volume!
A right click on the first volume there wouldn't have seen the "Delete volume" option greyed out either. Nuke that and create the new 64gb choosing the format option after for NTFS. I have a pair of 125gb drives here with a 10gb Linux volume as second made the Mount point "" for Grub where I can pull data onto the first 104.5gb data partition for transfer or recovery purposes when booted live from the stick.
You can see the fast reference there to the DM being the only place that will appear with the Delete volume option .
For seeing full access to the 64gb drive there you would need to grow the partition only after reformatting it to NTFS or nuking the drive and once a single NTFS volume is made bootable extract a 10 iso's contents onto the new volume. The 8gb size flash drive however is quite adequate for 10 media however. On a 32gb flash drive for the "4 in 1" project outlined in one thread last fall before the Threshold 2 update arrived I believe we had the 10576 build at the time just out and available at the MS Tech Bench Program download page to extract the contents of both Dual edition ISOs into the 32bit and 64bit folders you would clear out first from the MC tool download.
Thank you everyone for your suggestions. Windows 10 itself could not fix this. Disk manager options (certainly any I wanted) were greyed out.
So I did download and install MiniTool Partition Wizard free:
That allowed me to follow on from the place I had got to of an unallocated 64GB, create a partition, set it active and set it primary. WHen I was about to scream because nothing was happening I realised there is a big APPLY button to press. Pressing that enacted all the changes and the 64GB USB stick is now back to visible and usable in windows.
Clearly MiniTool Partition Wizard free: is a very useful tool.
Thankyou forumites. THis is so much more useful a forum than the windows community. I wish I had found it sooner.
I feel my problems with this thread were brought about by using the media creation tool, which did stuff to the usb that windows 10 could not undo. In terms of Windows 10, I am still on Build 10240, and had been going to use mct to attempt again to upgrade to 10586.
Instead, I shall now search the tenforums site for the best way to do so.

Once you are done with the upgrade, you can remove the virtual drive letter by right clicking on it and selecting Eject. That will not delete the ISO, you can either keep it for future use or delete the file itself.

Agreed. I have never tried to create partitions on a flash drive. I've doneit with hard disks in Windows since XP, for a dual boot system, but I'm not playing around with such things now.
This is what I have conveyed to a number of people over the years that not everyone will want to use or even feel comfortable using a command line rather then the gui method. Keeping a few live Linux distros here as well as the latest GParted cd for work while not booted in Windows can be handy at times while the Mint. But whichever partitioning option is used you will want to see this when going to add a second partition on any flash drive other then a mountable Linux volume or swat part when seeing a live recovery stick made up.
With GParted or the Gnome Partition Editor as well as the DiskPart tool you wouldn't see that warning appear! The MiniTool program does however and only confirms what I have been saying.
