Removing Vista from Dual-Boot System Vista + Windows 7

Hey guys, I've been looking through the forum and found some similar posts, but wanted to make sure that I understand everything before actually proceeding. I have a HP HDX 16t which came with Vista Home Premium 64 bit. I used the Windows 7 Upgrade Disk to do a clean install of Win7 on a new partition (I only have one hard drive). I would now like to remove Vista completely. I am attaching a pic of what my Disk Management shows. Thanks in advance for any help.

This great new tutorial from Barefootkid will show you with pictures exactly how to accomplish this using the best partitioning tool for Win7: http://www.sevenforums.com/tutorials/93322-partition-wizard-use-bootable-cd.html

Use Option One in the tutorial and substitute your Vista partition for the 100mb boot partition he refers to there.

Read the Note as once you delete Vista partition then Resize Win7 into its disk space and mark Win7 active, you'll need to run Startup Repair up to 3 separate times with reboots to write the System MBR to Win7 and start it up.

Back up your files and a system image externally as Resizing operations can fail although we have not had one fail in a couple hundred of these operations we have helped with here.

Thanks Greg, for your quick response. I read the tutorial, and it seems pretty straight-forward. I will back up the stuff that I don't want to lose, and give it a go.
