This may seem like a real noob question( but hey I am a noob

). Anyway Im confused about being connected via USB to my PC when flashing cm7. I already flashed once which resulted in a boot loop so im attempting a flash again. The first time I did it I was not USB connected at all. However, I've been reading and watching tutorials and some say USB connected, some say USB mounted, and some flashes were done with no USB connection at all. I'm just wondering if it matters at all which way you flash. Can Someone clear this up for me so I can finally get this flash thing over with!...Ugh!!

thanks lol
