I deleted my Boot Camp partition in Disk Utility (as usual, Windows wasn't working and wouldn't fix). I resized my Macintosh HD partition to cover the whole drive and repartitioned. Now Disk Utility says that the partition's capacity is 160 GB and that I've used 40 GB... and that 70 GB is available. My Boot Camp partition was 50 GB. I've read that to fix it I have to boot from my install DVD, go to Disk Utility, set the number of partitions to one, and delete the entire drive so that there's zero data left. Then I'd reinstall OS X and restore from a Time Machine backup. As of now, I have no external hard drive. Is there any other way to get this issue resolved?
