Why don't I get the white message after restarting the comp
My disk is only allowing me to reinstall on a bootable drive. Why don't I get the black and white message after restarting the computer that I need to hit any key to open up the disk so that I can install on a data only disk. My computer does not recognize my Windows 7 auto function. My boot sequence(CDROM and HD) has been changed several times without correcting the problem. I had a code 39 problem earlier indicated in contol panel and corrected the problem only part way.
In the past I have had two ways to install windows 7 since Oct 08. Something is wrong with my computer. Please help!!!!!

I Found the answer in Computer hope. If a bootable disk does not boot keep holding the key down until it does. How to enter the BIOS or CMOS setup. in other suggestions. It works for a windows install disk but a homemade bootable I am not sure.
