Thank you for your reply. You keep directing me towards your instructions which detail removing windows from the EMMC disc. I think I now see why…
I had hoped to keep the operating system on the 32 GB drive as a back up, but the problem I have is with Windows search.
I have spent a few days trying all the options I could find for window search problems with no success.
I now think it’s a problem to do with indexing.
In the indexing options bit on Windows 10 I can’t get my C drive (where I have put all my documents) to appear in the first “locations being indexed” window. It does appear if I go to ‘modify’ and select the C drive (and deselect the D drive) , but it never appears back in that first window, just the D drive, and a usb hdd.
Before I format the D drive does this sound like a problem that will be fixed by reformatting the drive.
