I want to resize my system reserved partition, as I get an error "we couln't update the system reserved partition", when trying to update to Windows 10 Threshold 2. Apparently, the system reserved partition is only 100Mb if you upgraded to Windows 10 from Win 7, and you need it to be 350 Mb. I purchased Hard Disk Manager suite 15 to do this, but the option to move/resize the system reserved partition is not there. I have created the necessary space to the right of the system reserved partition in the disk map. Does anyone know if it's possible to resize the system reserved partition with Hard Disk Manager suite 15 ? I've read that some free partition management software can do this.
