How do I merge two partitions into one?

how exactly did you go about this?

yes, you can delete Boot camp partition, but it's best to do it with the boot camp utility.

usually after you delete a partition & there's free space available, you can drag the handle (lower right of the partition block) down unil it covers the free space. Click the partition button to finalize.

also, 149Gb will all you will get with a 160Gb drive after formatting. My 120Gb drive was only 111Gb after HFS+ formatting & my current 250Gb is 232 Gb after formatting, FYI.

Not sure where to go from here.

How & what did you do this with?

You likely just wiped the drive...

Somehow my last response to you didn't get posted. Once you do your backup, see if you can use Kappy's instructions to get back to a single partition:

What I had tried to post earlier was to see if you could highlight the unwanted partition and then use the size window to reduce the size to zero. It looked like that option might be open. If you can do that, you might be able to expand the OS X partition the same way. I notice that your unwanted partition is shaded gray rather than white. I experimented a bit with adding and deleting partitions on my internal hard drive and had no problem, but all the partitions were white and not gray.

Before restoring from Time Machine, be sure that you can format the drive the way you want. Someone posted earlier that you may have to use Windows to get rid of a windows partition, and I think I've heard of that before.

Good luck!

It's going to take roughly 12 hours for my backup to finish, meanwhile does anyone think that booting Disk Utility off the Leopard DVD will work in any way?

backing up is always a good idea when you are working with partitions.

I had a similar situation, but my partitions were in reverse order. I had the empty partition on the end and data at the start of the drive. I was able to merge my partitions using Terminal.
I booted up on my Leopard DVD opened up Terminal
I did:
diskutil mergePartitions "Journaled HFS+" "Macintosh HD" /dev/disk0s2 /dev/disk0s3

That did the trick for me. I'm all on one partition with no data loss or without having to restore from backup.

Careful though, because I don't think this would work given that your empty space is at the start of the drive.

The instructions say this:
"All data on merged partitions _other than the first_ will be lost."
