Guest OS: Windows 7 Pro.
Update to Windows 10 constantly stopped with 0x80070070 0x2000c error.

What helped:

• Changed the OS Version in VM settings to "Windows 10 (64 bit") - must be done when the VM is turned off
• Enabled PAE/NX
• added disk space:

  Code: Select all

  C:/Programme/Oracle/VirtualBox/vboxmanage.exe modifyhd "c:\Users\VBoxFan\VirtualBox VMs\MyVBox\MyVDisk.vdi" --resize 95000 

  and then resized the disk inside the guest OS
• Changed Graphics controller to VBoxSVGA (not sure whether this is really needed)
• uninstalled VirtualBox Guest Additions (+reboot)

Doing a quick search for "0x80070070 0x2000c error" shows that the error is due to limited hard disk space in Win10. What I think did the trick were:

As for the rest of them:

• PAE/NX: I don't think it's relevant for a Win10 Guest.
• VBoxSVGA is the new vGPU, you should stick to that. But it wouldn't produce that error that you were getting.
• Guest Additions: you should definitely re-install them.
