Windows 10: Unable to use back up/restore ?!

I want to back up the C drive which has the OS on, just in case the hard disc crashes, I have done this in the past without a problem but in windows 10 I get a message that it cannot be done because the target drive has insufficient capacity, however the back up file is 37.5GB and the drive has 345.57GB capacity available. I think I read somewhere that backup requires the same size as target drive as the drive the OS resides on.In my situation that partition is 903GB.If that is the case, can I safely reduce the size of the partition to say 300GB.

Restoring Windows 10 Image using Macrium Reflect


In addition to the above. Here's my suggestion in step by step.
I assume you have Macrium Installed in your current HD and already made a backup copy.

1. Connect your new HD via USB port and boot up.
2. Run Macrium, click on Restore tab then select the Backup Image that you made to restore
3. click on "select a different target disk" then select your new HD as destination
   
   
   
4. Proceed to restore then Shutdown and disconnect the old HD and replace with the new HD
5. Boot up with your new HD.

How to delete inactive System Image Restore Points in System Restore

Windows 10 64-bit.
When I click "show more restore points" in System Restore I see a bunch of old "system image restore points" that were deleted in past and do not correspond to any currently active restore points. Clicking any of these old restore points, I simply get an error message saying they could not be found, and to select another restore point instead.I would like to delete these restore points listings but have been unable to do so.
So far, I have tried steps mentioned below without any luck :

Disk Cleanup through (C Properties
Disable System Protection (OFF and ON) in System Protection for OS (C
Disk Space Usage to minimum (slider button all the way to the left then 'Delete all restore points for this drive'),
Delete all shown Restore points in CCleaner (the problem ones do not show here),
Reset Windows Backup to Default in Windows 10 with 'Reset_Windows_Backup.bat' utility.

Any suggestions highly welcome.
