I have a Macbook Pro with 3 partitions:
- HFS (OSX)
- FAT (Ubuntu)
- NTFS (Windows 7)
and I want to format only the OSX partition and do a clean install without touching the other operating system partitions. In order to do this I also have to format the MBR partition or erase it? I have rEFIt, and I know it has a utility that checks/repair the MBR or so I think so, should I use it after I do the clean install?
