Hope you don`t mind the interjection folks
Unfortunately holding 0 like the linked articles suggests is doing nothing for me.
If holding down the zero (0) key did nothing it means that the Toshiba Recovery partition has been formatted, to confirm this follow the steps below and post a screenshot for one of us to advise you on;
· Right click This PC > Manage > Disk Management.
· Click Start Menu and then type Disk Management to search.
· Click Start Menu and type cmd to open command line and then input compmgmt.msc and then click Enter.
Grab a screenshot and attach it to your next reply for us;

Do you know what else I can try?
If me, I would clean install Windows 10.
Upgrades to Windows 10 on brand name computers are notoriously troublesome and unfortunately nine out of ten times the best and most efficient fix is a clean install of Windows 10, if this is required in your particular predicament may I suggest that before you do the clean install that you download and save the drivers for the MB to a USB thumb drive, after any clean install, install the MBs chipset drivers and test, most modern hardware gets along fine with Windows drivers but not installing a MBs chipset drivers after a clean install can cause folk no end of problems.
