    Is there a way to reinstall osx while keeping my windows partition intact? I realized I need a fresh install but not sure how to go about doing it. Any help would be greatly appreciated. Thanks!

    Just boot the OSX install DVD, Use Disk utility to erase the mac os x partition, while keeping the NTFS/Fat windows partition.

    After that do the Install on the newly erased partition. And then install rEFIt in the newly MAC OS X. Restart and there ya go, you have a beautiful dualboot startup screen ;).

    Do you need rEFIt?

    I've always used rEFIt as a bootmanager, because Bootcamp doesn't support multiple partitions (my setup is with 2 HFS partitions and 1 NTFS). So if something happen to 1 of the OSes (Windows or MacOS) I can keep all my files on the 3rd partition and just erase/format the (corrupted) OS partition.

    So if he can manage to boot into windows without installing rEFIt... then he doesn't need it. But if he can't... I bet rEFIt will do the job...
