I have checked Will my other partitions be wiped when doing a clean install of Mavericks? but I'd like to make sure whether a clean install of Mavericks to my specific OS X partition won't mess up with the rest of the disk. OS X generally doesn't recognize other partitions types beyond the Windows types.

Is such clean install prone to error even if I take care of asking installation to not touch the partition scheme?


If you clear you partition using Disk Utility and then boot into Internet Recovery or install from another location (for example a USB flash drive) you should be fine, OS X will only be installed (and only effect) the partition you choose to install it on at the start of the installation process.

  • does that means I have to first clear the partition before the clean install? or is it safe to just overwrite current installation if there's such option. – pepper_chico Jun 4 '14 at 17:56
  • It's how I choose to do it. You can just launch into the boot disk and it will overwrite it for you. – Harry Beadle Jun 4 '14 at 18:36
  • thanks, I have already erased it first from disk utility in the Mavericks thumb drive – pepper_chico Jun 4 '14 at 18:41
  • ok, I was using rEFInd already, it was a matter of reinstalling it after the clean install, no problems =D – pepper_chico Jun 4 '14 at 21:31
  • @pepper_chico Good! – Harry Beadle Jun 4 '14 at 22:37
