I'm trying to upgrade a Dell Venue tablet from Windows 8.1 (which came pre-installed) to Windows 10. I downloaded the Microsoft Media Creation Tool (or whatever it's called) to immediately start the upgrade process. At first it told me that everything checked out; here is an actual screenshot from that tool (below) indicating that I met the requirements for CPU, Memory, and Disk space.

It then says it will automatically start the Windows 10 download in 9 seconds. Once it does, however, instead of actually downloading anything it just gives me the following error message: "Not enough disk space, please run Disk Cleanup and try again."

error

I find it really frustrating that the tool, one moment, tells me I have enough disk space, and then in the next moment tells me I don't. I did run the Disk Cleanup tool, which was only able to clean a whopping 10 MB, because I had already done a factory reset of the tablet (meaning it didn't have anything on it). As you can see, I have 16.7 of 22.9 GB free after the factory reset. Supposedly it only needs 16 (which I have), so I'm confused why it's not letting me upgrade.

space

Unfortunately as you might have guessed it is literally impossible to free up any more space than the 16.7 GB listed, since that is what is available fresh after a factory reset. Any advice on how to proceed? How can I get Windows 10 on this machine?

  • 16GB isn't enough to use the media creation tool, you can use the tool to create a bootable flash drive, but the upgrade process requires more the. 16GB. You can also format the device and install Windows 10 allowing it to detect the Windows 8.x key – Ramhound Jun 8 '16 at 21:55
  • use USB flash drives to store the WIn10 data: channel9.msdn.com/Shows/The-Defrag-Show/… – magicandre1981 Jun 9 '16 at 4:36
  • have you tried the USb thumb drives to use 1 of it as temporary drive? – magicandre1981 Jul 16 '16 at 18:35
