My friend Mac Mini that has Windows 7 Installed will sometimes boot but certain times it will freeze on boot and he restarts it, goes to startup repair, Again reboot but same issue. Any ideas?

I don't know, but it may be the fact he's using Windows on a Mac...

No, not really. Nobody I've seen here is an expert with Apple products, at least not so far. You also didn't specify if he's using Boot Camp or Parallels or Fusion or some other Virtual Machine software to do it. You didn't mention what patches or service packs he has, what his computer specifications are, any of that. You're way better of asking this sort of stuff on the proper forums (the ones who make the products) with the details I mentioned.

Is there ever an issue booting into OS X, or only into Windows? Or is Windows the only thing installed?

If he bootcamped it, did he make sure to install the Apple compatibility stuff for Windows?

Bootcamp and all was done but now it fixed after my friend was the one the messed up.. While entering the OS he keep on pressing enter and caused it to freeze and go into start up repair. But thanks guys for helping.. I take it as.
