Not at all, just boot from your Win7 install disk, choose Custom and delete all the partitions, create new ones you want, then format and install Win7 to the first one.
Recovery partition has no bearing on the new OS, just wastes space and won't work anyway in most cases after new OS is installed.
Plenty of reports in this thread that clean installs were done from boot without any traces of previous O.S., so it can be done, and if necessary the workarounds to get activated.are right here.
