Hello- I just upgraded two of my MacBook Pros to Lion. My windows partitions on both of them are now gone... I tried searching in the forum and no one seems to have encountered this problem. If I look in disk utility, the partition still appears to be there, but it is not mounted in finder nor can I start up from it while holding the option key. Any suggestions, or did anyone else encounter this problem? One MacBook Pro is running Windows 7 Enterprise, and the other Home Premium. Thanks!
