Tried to boot into Bootcamp today but got a bless fail no matter how I tried to boot into it, message below is
from Bootchamp.

The Bootcamp partition is on a a drive which contains El Capitan.

Bootchamp does not work with SIP, so Yosemite is the last fully supported operating system for it. It will work under El Capitan, but you have to disable SIP. SIP prevents use of the bless command.

The developer abandoned BootChamp after Apple implemented SIP, so its days are numbered. You might want to look into alternatives.

Yep. The dev hasn't updated BootChamp in over a year. But yes, disabling SIP should do the trick.
 
I solved the issue by doing a PRAM reset, all works again now under Elcapitan, and I do not recall disabling SIP, how can I find out if SIP is disabled ?
 
In Terminal, type csrutil status then click enter. That will let you know if it's enabled or disabled.

SIP is enabled and it all works after doing the PRAM reset.

Well that's really interesting news. The BootChamp developer himself says that it won't work with SIP enabled, and literally stopped development because of that.
 
What is SIP and what happens when you disable it?
This article has a pretty good - and short - explanation about SIP.

Most folks here will tell you that they may disable SIP for specific purposes (installing some apps that won't install with it enabled, for example), then re-enable SIP after the task is complete.
