Debian 9.0.0 iso

[sarez45]

The full version of Debian 9.0.0 iso will not install from a flash drive. It 
boots into the live desktop with no option to install to hard drive. The CD 
version will install. The one from the flash drive looks for a CD after 
choosing the language and keyboard language. What is wrong with your iso's. I 
have installed many Linux and Debian systems and never had any problems with 
installing from flash drives.
