The windows installer should offer to format the drive, but if you want to start over fresh open up Disk Utility in OS X select the highest level of you 8gb SSD
and then click erase and format it to FAT32. (Windows DOS or something like that, I believe it's called in Disk Utility). This will completely wipe the drive and erase all contents so only do this if your sure you want to install windows.
From here you should be able to do a clean Windows 7 install.
Hope this helps.
