please help! my screen goes black after xbox logo

i tried to install an updated version of avalaunch dashboard from the one i had, right after i put it on the xbox hard drive, i went to return to ms dashboard from evox and the screen went black, now everytime i turn on the xbox it goes black after the logo. Is there any way to get back to evox so i can ftp and delete the files i added?

 

u have to put evox on a cdr or dvdr

 

i put evox on BOTH and still nothing...this really sucks...its like my box loads up from the hard drive before it looks for cd/dvds.

 

make shure you got the ide cables inside the xbox pluged in correctly

 

all the cables are hooked up...i just think that for some reason it doesnt look for whats in the dvd drive and then tries to load the dashboard that is bunk. if i got someone elses Hard drive could i load up evox with that and then, with evox loaded, switch hard disks with the xbox still on??? then i could ftp to my drive that is messed up and fix it.

 

i dont think u should switch drives when the xbx is on because it reads the information from the hd
