How to unpartition a MacBook Pro 2010

Question

So a few days to ago I had about 90 GB left on my Hardrive so I wanted to partition my hardrive, 55 GB Windows and 35 Mac. But since I had to do something else it was urgent aswell I stopped the partition and now it says I have 56.7 GB left, and no Windows. I have reinstalled Mac OS X Lion (updated from Snow Leopard), but still have 56.7, I Verified both Hitachi's and Macintosh HD's Disks. Both came out saying OK. So I don't know what the problem is.

Answer 1

Never - ever - stop an in progress change to partition table.
Try Lion Recovery and see if you can readjust the size of the partitions after repairing the drive.
If not you will need to erase the hard drive and then restore.
Also, you want to keep the Lion ESD package installer for reinstall.
Backups: a good rule is to have bootable backup along with TimeMachine, so make a clone of OS X on an external drive, boot from the external clone, and do the erase and clone / restore back.

An all-in-one backup drive for both clone, emergency, and Time Machine
Emergency OS X 20GB
Clone OS X working system (200GB?)
Lion Recovery partition 1GB
TimeMachine 3.5X the size of your data perhaps

How to Restore entire system:
The usual procedure is quite simple:
•Start your Mac from your Install disc (be sure to use the right one). [or Recovery HD for 10.7]
•Select Utilities from the menubar, then Restore System from Backup.
•Select the backup you want to restore, and where you want to put it.
•Wait while your Mac does all the work  (copying all your stuff).
•Start up normally, and you're back in business!  from: http://pondini.org/TM/14.html
You may want to immediately turn Time Machine OFF, as the next backup may be a full one, of everything you just restored, taking lots of time and disk space.
