Hi, today I tried to partition 25gb of my late 2006' Macbook Pro to Windows as I want to play League of Legends. Whenever I try this it will load for up to 15 minutes, before telling me I need to repair the disk. So I go into Disk Utilities to try and repair it, but the option isn't available. So it tells me to verify disk if repair isn't working. Great, so I go ahead and do this and it says ' The volume Alphamac 12 needs to be repaired Error: Filesystem verify or repair failed '' Where do I go from this? Any help is appreciated, thanks.
