I don't think there's any option in Windows to move those data. So probably it's right there from the start, but you only see it now.
Be careful when you reinstall to have the disks used as you prefer.
I have a desktop pc running Windows 10. I do not have a Windows CD, but have already downloaded the Media Creation Restore Tool onto a USB flash drive. I have a SSD drive as my Operating System drive and a second hard drive for data. I decided to move my data folders (Documents, Music, Pictures etc.) from the User folder on the C Drive to the second data drive, using Properties, Location and Move option. At no stage did I touch any Windows system files, but I now find that the Boot, Boot Mgr and System Information files are now on my second drive. If I disconnect this drive the pc will not boot up from the C Drive. Can I simply replace these files back into the C Drive, and, if so, where do I place them. The pc works fine all the time the second drive is in place. I do not want to simply reinstall Windows 10 from the USB flash drive, as this would then mean reinstalling other programmes afterwards.
Your help please.
