wiped vista for 7, now OSX error

[lorvar]

I've googled this to death, I get my boot options on start up on my HP laptop, I select OSX and get this"nst_mac.efi" file missing or corrupt. Fine makes sense because I wiped my Windows partition to install Windows 7. How exactly do I fix this without reinstalling everything from the start?

Re-add the entry in Windows 7. If its still reporting missing/corrupt check the NST folder to see if the file exists.
