Issue installing windows 7 using Boot camp

I had windows installed on MAC using Boot camp. I got low disk space warning, So Google it if i can expand disk space without reinstalling windows. Some one on a apple blog mentioned that it was done using "Minitool partition". Tried it, seemed like it was working but later it failed and windows was corrupted. So i decided to reinstall window using boot camp from beginning. I created windows install disk from ISO to 32GB pen drive, Downloaded boot camp drivers and started installation. Windows started copying files, as soon as it started installation gave error message "Windows cannot be installed to this disk. This computer's hardware may not support booting to this disk. Ensure that the disk's controller is enabled in the computer's BIOS menu." Please suggest how can i fix it !!

Thanks
