It's been a while since i visited robinhoodsplayground,and i've come back because i need some help.i know i can trust you guys to help.Well i'm flashing my xbox 360 using iPrep 10.I first prepared the usb drive.Then when i booted the computer onto the flash drive it said,"Remove disks or any other media.Press any key to restart" Ive been getting that every time i try to boot off of it.Is there any possible fixes to this.I'm running windows vista:home premium,have a Intel(R) ICH8R/ICH9R/ICH10R/DO SATA RAID Controller.I'm flashing a BenQ drive and using iXtreme-THX_v1.6. This is the only problem i am having as of now.Any help would be useful,thank you
