Should I have 3 hidden volumes?
Probably yes, System Reserve approx 350Mb where the boot files are now kept, Recovery approx 450 Mb where the tools to repair windows is store (x: drive) plus your satellite may have its original recovery partition approx 12Gb where the laptops win 8 recovery image is located (no longer required as you have up graded to win 10).
C: should not normally be hidden ( works laptops may have C: hidden by the IT department to prevent unauthorised access) as that is where windows is located.
It is often worth running the Start up repair several times as windows may not find anything to repair or says it can't repair.
Again worth running repairs and resets from a USB / DVD rather than the hidden tools partition especially if there is hard drive corruption.
You could also run chkdsk /f /r from the command prompt to check for hard drive problems especially if those problems are in the boot sector / hidden system reserve area which prevent windows booting.
