Hi, 1st post here. I have been searching all kinds of forums and reading tons of posts but not really finding out how to resolve the issue I have. I upgraded to Lion this morning and OSX is fine. However, when I attempted to boot into the Win 7 bootcamp partition, it starts up the generic Win 7 splash screen then BSOD's quickly with an "Unmountable_Boot_Volume" error. The model is a '09 MacBook Pro 13 inch aluminum body. Prior to Lion it was running Snow Leopard 10.6.8 and the bootcamp partition had Win 7 64 bit Ultimate which worked perfectly. I see the Windows volume in the boot manager. I see the bootcamp partition in Disk Utility. Repair Disk is grayed out and if I click Verify Disk I get "verify volume failed: Invalid request...don't know if this is normal or not. The format is NTFS and capacity/remaining drive space seems normal from when it worked before. When I try to do the Win 7 repair options the 1st thing I notice is that the Windows OS isn't listed in the System Recovery Options window. It states that if it isn't listed then load drivers then install for the hard drives. Not sure what to do here actually. Also, if I go to the Recovery Tools and select Command Prompt I can't cd to the C: drive, I get "The volume does not contain a recognized file system" (assuming C: is the bootcamp partition). Not sure what to do at this point. Any advice would be greatly appreciated. Cheers!
