I'm assuming you don't see the windows 7 install usb at startup? ( holding down the option key? )
Alot of the tools to create USB boot disks simply just don't work..
try microsofts tool
which you'll need a windows installation to use anyhow.. ( use your parallels for this?? or accost your mates PC? )
I'd recommend you install windows onto a NTFS partition BTW..
But maybe you can try repairing your disk first using diskutil in OSX.. maybe it'll fix up the boot disk entries and allow you to boot your install that you did with parallels..
