Delete old partition with Vista on

Hi guys

I have an old partition containing Vista Home Premium installed on a partition of my drive which I can dual-boot into. To delete it is it as simple as formatting the partition from within 7? Will this sort out all the dual-boot stuff and stop my computer from messing up

(the Vista partition still holds the "Primary Partition" label but the 7 one does too)

It looks like Vista can be deleted in Win7 Disk Mgmt with no problem since it contains no boot files.

However you have a lot of wasted space with a Recovery Partition that may no longer work after Win7 install, and a boot partition which Win7 is booting off of but which has a 1.46gb space not needed any longer since you no longer have the factory utilities installed with Vista.

Best approach would be to clean reinstall after deleting all partitions as described here: Reinstalling Windows 7

Until then you could recover the Vista boot files and the first 3 partitions space back into Vista partition using free Partition Wizard bootable CD and the Vista Repair CD. Boot PW CD to delete each partition except Vista, then mark Vista partition Active. Now boot the Vista Repair CD to run Startup Repair up to 3 separate times with reboots until it writes the System boot files to Vista and starts. Back up your files and a Vista backup image first.

in the long term i plan to reinstall 7 anyway as I corrupted certain things that can only be fixed with a clean install but i would prefer the ability to dual boot 7 with itsself so i am able to move the files with ease

I have been reading the tutorial here and am interested to know if this method will work for me without performing extra steps (just delete the old partitions within the installer, and then create a new and stick 7 on it)

also, if this fails during install is there a way by which i can restore my system to its previous state?

It is the method I use for a clean install of Windows.

Its main benefit is that you can decide at the outset how many partitions you're going to have and how big they're going to be. However, one partition will be used for the master boot record whose default size is 100MB, but you can of course make it bigger if you want.

This method has never failed me so I'm not 100% certain you can revert back to your old setup if it did, but I would have thought once you've cleaned the drive ready for your new partitions, there's no going back.

The process to get a perfect reinstall is described here: Reinstalling Windows 7

Until then you can delete the Recovery and Vista partition but not the partition which is marked System as your boot files are on it - until you recover them back into the Win7 partition using the method I gave you earlier.

If you tell us exactly what you want to do, we will customize the steps for you.
