i am a mac user. I have realized a triple boot system (Mac OS, Windows 7, Linux). Because of this issue i am using a GUID Partitiontable. I have formatted the partitions with gparted in a Linux Live Distribution with GPT. I have now already installed all these three OS. My Problem is that my data partition is not reachable under Windows 7. In the Disk Managment it is not possible to initialize as an gpt drive, because option is "greyed out".
Is it possible to tell Windows 7 that after rebooting this is a GUID Partitiontable so that Windows 7 dont miss interpret the Partition table?
Can someone help me please?
