I have 3 partitions and dual boot Mavericks and Windows. I got Mavericks booting with Chameleon first and then installed Windows. Once done the windows install you have to set the active partition, using the cmd prompt and DiskPart.exe, to the Mavericks partition. My 3rd partition is where Chameleon is located.
When partitioning the drive (using your existing OS 10.7 install) set the drive up as a GUID. 1GB partition HFS+, OS X partition HFS+ and Windows partition FAT. When installing Windows you will have to reformat the FAT partition as NTFS using the Windows installer.
Hi, I don't know if you can chime in, but my problem is that I had a Bootcamp partition prior to going through with installing Mavericks. I was booting it (or Lion) by either going into the startup disk control panel or by holding option down at the chime.
So, I need to know what to do in my situation, since I already have the Windows partition.
I had read that the issue is with Windows setting itself up as a startup partition (BTW, it somehow damages the chameleon partition, I had to re-bless every time Windows started up on me, or I would no longer be able to use the boot loader), but I cannot find a guide that sets up the drives given my circumstances.
