Reinstalling OSX While keeping Windows 7 intact.

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...
