Trouble with partition
I am using Macbook 2009 with Mac OS 10.7.5, before I purchased it with Leopard but upgraded via App Store later to Lion. I am having trouble after repartition my disk. Before, I devided my space into 3 partition: 1 is Mac HD, 1 is for storing purpose, 1 is Bootcamp for Window 7. However, yesterday, I decided to delete 2 other disks and only keep the Mac HD as start up disk. But when I repartition, Disk Utility is seem not working, so I decided to turn the Mac off, which I know is a not really good idea. After restart, the Mac HD appear to have full of capacity (160GB) but it is not.
The capapility is 159.7GB, but the total of Available and Used is only 44GB, which means all space for 2 disks I deleted is no more avaiable. Disk Utility also suggests me to use Recovery HD so I restarted my Mac and hold the Control+R but not thing happened. Then I google and hold on the Option/ALT instead, but it only appear one disk, which is Mac HD and nothing else. I lost my Installing CD. Please help.
MacBook Pro, Mac OS X (10.7.5)
