Windows 7: Windows 7 & Vista Partitions

Windows 7 & Vista Partitions

Hello :)

My Hard Drive is split into two partitions, one is 40GB the other 90GB. On this 90GB one is Vista. Recently I got 7 and installed it on the 40GB partition. I now want to remove Vista, and extend the 7 partition to use all of the space. When I try to delete the Vista volume, it says 'Windows cannot delete the active system partition'.

Someone said to right click on the W7 partition and click 'Make this the system partition' but I'm not sure. I'm guessing some important files are on the other partition?

Anyone solve this for me?

I am not familiar with this option, but go ahead and click "Make this system partition". Before you do this, however, make sure that you have a Repair Disc handy.
System Repair Disc - Create
Then you can delete the Vista partition. There is a good chance that you will no longer be able to boot Windows. At that point, boot from the repair disc you just made and run a Startup Repair 3 times or until it works. If it still doesn't work, make sure the partition is active.
Boot into the install/repair disc and wait for it to load
Choose “Repair my computer”
Select “Command Prompt”

Type “diskpart” and press enter. Do not type the quotes.
Enter “list disk” and note the number of the disk you want to install on.
Enter “select disk n” n is the number of the disk.
Enter “list partition” and note the number of the partition you want to install on.
Enter “select partition n” n is the number of the partition.
Enter “active”

Then you can run Startup Repair again.
