When you clean install Windows 10 - there are 2 -4 partitions created. Windows knows what it needs.
I'm not sure what you did, but I understnad there was an issue with the first attempt.
I'll wait for the images simrick requested.
The 500 MB is the System Reserve partition - leave this alone, it holds WinRE and Boot configuration
The remainder of the drive is devoted to your Windows boot and possibly a Recovery partition
UEFI firmware is different, I'll have to read the thread to see if you already answered MBR/BIOS or UEFI
I'd like to see your Disk Management.
Step 1: Download this zip file (contains dmDskmgr-vd.mmc)
Step 2: Double click dmDskmgr-vd.zip to open the compressed folder
Double click dmDskmgr-vd.mmc to launch the custom Disk Management console
You'll get an output similar to this:
Press Alt+PrtScn to grab a snapshot of just the Disk Management window
Open Paint and Ctrl+V to paste it, then save the image
Attach the image to a new post.
Option 2: Use Disk Management in the x-Menu (right click the Windows logo, select Disk Management)
Select View > Bottom > Disk list
Maximize the window and grab the screen shot.
