Hello

So i have just bought my self a new gpu sapphire rx 8gb after installing it and installing the drivers from the disk i closed my pc case and my pc shut off and keeps showing ma an windows bootb manager 0xc00000000f error

 

Spec

Evga 500w 80 bronze

ASRock B450M Pro4 f 

Patriot viper 2x4

And every time when i try to use start-up repair it gives me a message "press advanced options to try to repair your pc or shut down to turn off your pc"

 

And every time when i  write bootrec /fixmbr and then bootrec /fix boot it tells me access denied

 

And if i reinstall windows will that help??
