I've got a late 2010 MacBook Air that came with OS X 10.6.6 installed; I have never upgraded it to 10.6.8 Snow Leopard or to 10.7 Lion.
I dual boot with Windows 7 installed using boot camp. I use rEFIt as my boot loader.
Disk Utility in OS X shows:
- Macintosh HD is partition 2
- partition 3 is an empty FAT partition
- Windows HD is partition 4
I don't know why partition 1 doesn't show up there. In Windows under Disk Management it shows up as 200 MB (GPT Protective Partition)
When booting, rEFIt gives me these options:
- Boot to Mac OS X
- Boot to Windows on Partition 4
If I upgrade OS X to Lion, is there any risk of breaking my Windows install, messing up my Windows partition or the boot loader or anything like that?
