We would SEE it in 8min after detonation, but years for the pressure wave. Without going into a lot if thought, we would probably be dead in the same 8min since the Earth's magnetic field would be overpowered by the non visible radio active particles that still have the ability to travel at light speed.
People don't realize how large the cosmos is. If Earth was the size of a marble, the sun would be a beach ball, the solar system would be seven miles across at that scale (only including planets, not the Ort cloud).

There was a solar flare in the 1800's where entire telegraph infrastructure was shorted out, even causing fires int he Northern Hemisphere. Something like that today would wipe out every electronic device in it's path, including satellites.

This nova stuff is silly. Our sun would first begin to physically expand, possibly to the orbit path of earth, but also possily altering the orbits of the planets, mind you it will probably take about 5B years to start this and another 5B to expand fully. If earth is somehow not destroyed or released from orbit it the sun would then collapse, probably rapidly, and over the next .5B years would probably become one of several types of dwarf stars.
That's of course forgetting that the sun does not presently contain sufficient mass to go nova (we think) in any case, and ignoring how humanity probably won't even last another %.5 of the sun's current phase time.
