Got Win 7 iso file and transferred it to a usb following procedures by boot camp assistant. After creating a boot camp partition, computer reboot and I can select language under Windows. But after I click install, a black screen appear saying "no bootable device -- insert boot disk and press any key". I am now stucked here and cannot go back to OSX even unplug and reboot. How can I go back to OSX? My USB should already be a bootable disk. Why the computer still say no bootable device? Thanks for any advice!

Mine is an iMac late 2013. Managed to boot back to OSX by holding the option key during start up. Problem now solved by preparing another bootable USB from install CD using Wintoflash. Successfully installed Windows 7 now by boot camp. Thanks for all your advice!
