Default [Q] Problems flashing boot.img

I found myself needing a backup phone so I dusted off my old HTC Inspire that has been put up for years. To make it more useful I wanted to put CM7 on it. I got the bootloader unlocked and clockwork recovery installed and flashed CM7 and GAPPS. My issue is that any time I power the phone it locks up on a white screen with the HTC logo and requires me to manually flash boot.img again to get my phone booted in CM7. Anybody have any ideas? Why would I have to flash boot.img every time I power or reboot my phone? Please help.
