No, he is on WiiU.
Do not use Hermes installed, do not use cIOSX installers.
if you are on vWii, you need to install d2x v10 or v10alt for vWii only.
that's the only 2 compatible cIOS.
d2x cIOS installer for vWii.
If you followed the guide you linked, you should be fine.
you can try to re-follow it and re-install the same cIOS over, just in case the installation didn't completed correctly the first time.
Which USBLoader are you using?
the error should help you understand what's wrong
wbfs error not a Wii disc booting game please wait iOS 249 iOS reload blocked returned ret = -1
"wbfs error not a Wii disc". It means the ISO couldn't be recognized as a Wii game, it's probably a bad dump.
"booting game please wait" .. strange that it's still trying to boot the game if he said "not a wii disc" first.
"IOS reload block" is a cIOS d2x features, returning -1 often mean the function didn't complete correctly.
so, it could be :
your loader is old/not working on vWii.
your cIOS is not correctly installed, not the correct version.
