this doesn't have anything directly to do with windows, more the aftermath. i partitioned a 32gig portion of my hd with bootcamp 2.0 and installed windows. after deciding to use parallels instead, i used bootcamp to delete the partition. after deleting everything ran smooth no problem. i went to use my computer again the next day and turned it on and now mac os doesn't load automatically. if i let it try and load it gives me a black screen saying "no boot disk found press any key to restart" or something. if i want to load mac os i have to hold the option key as if i were choosing between windows and osx, but the windows partition doesn't exist when i do that just my mac hd. any idea how i can fix this problem without reformatting the drive?? i'm on a macbook pro if it matters.
