Here's the story. A couple weeks ago I successfully installed Windows 7 Home as a bootcamp partition using Disk Utility, not Bootcamp Assisstant, I clicked on my 750gb mac drive, clicked on partition, clicked the "+" symbol to split the HDD into a second partition, allocated 200gb for this Windows 7 partition remaining 550gb for Mac HD, made it into MS-Dos Format so I can format it into NTSF during the Windows installation; everything was working fine, I even was successfully running Parallels 7 with it. So here's my problem, the other day I purchased Windows 7 Professional, decided I wanted to do a complete new installation so I went into my Mac OS X Lion and went into Disk Utility, deleted the Windows partition, then dragged the corner of my Mac HD putting it back to 750gb. Now my bootcamp partition of Windows 7 HD is deleted so I went ahead and hit the "+" to create a partition for Windows 7 Pro HD, it gave me a Failed Error message, so I went into my Mac OS HD and repaired Disk, even hit the set permissions button), those both didnt fix my problem of creating a partition. So i go into bootcamp assistant and went through the process, i already have the mac drives, hit continue, then it showed me what i can allocate for Windows. It tells me I only have 345gb to allocate a Windows partition, but I should have 200gb ontop of that. My total HDD is 750gb and I only have 550gb available for me to use . How do I get the remaining 200gb i used from my old windows partiton I already deleted. By the way, I already allocated 750gb to my Mac HDD freeing up all the free space. Can anyone help? I can send screenshots if needed. Thank you!
