Still doesn't explain why it's listed twice though...

long time since I looked at Disk Management...so, can't say why listed twice.

Was your HP 17f065us originally supplied with windows 8.1? If so, the Recovery (D:) partition is for the factory reset back to 8.1.

As that is not particularly useful now, I would try removing its drive letter and see if that cures the problem of system protection not being able to find any drives. You may not be allowed to do that in Disk Management as it is marked as an OEM partition. If so, you can use Diskpart.

In diskpart, use the LIST VOLUME command. Note the volume number of the Recovery (D:) drive. then use the commands (with the appropriate number in place of '#')

SELECT VOLUME #
REMOVE

(This is reversible, you can give it back a drive letter by repeating the process, but use the command
ASSIGN LETTER=D instead of REMOVE, if you wish)

Hi,
Yes, HP 17f065us originally supplied with windows 8.1
I didn't do anything as yet with "diskpart".

Code:

Long story short since my last message.
I ran Disk Cleanup and cleared 4GB Windows Updates and I ran Win10_1709_.iso
