Deleting Vista After Windows 7 Install

It looks like the master boot record is on K, but I'm not 100% sure. It would be good to have a 7 install or recovery disk ready in case. If it is actually on C and you delete it, you will have to run a startup repair 3 separate times, with reboots in between. As for actually deleting it, please refer to the tutorials below.

Partition or Volume - Delete
Partition or Volume - Extend (to extend one of the volumes to use unallocated space)

Hello lolguy, welcome to Seven Forums!





You will need to mark the Windows 7 partition "K ?" as "Active" and do as many as 3 separate startup repairs with system restarts between each repair to create the boot file to Windows 7, have a look at the tutorial at the link below to get some perspective on this and if you have further questions feel free to ask.

If he just deletes it he'll have to use a 3rd party like PWBD to recover the space back into another partition; though it would be a good idea to do a wipe of the "Vista C:" partition first (before it's deleted) to remove any old Windows code and then it can be resized if needed.


Partition Wizard : Use the Bootable CD

Just to confirm that from the drive management shown the active drive is the C: drive and deleting this partition will render the win7 install un-bootaable.

This is not a major issue but will need the start-up repair as suggested above.

I assume from the fact that the win7 installation shows as K: that the install of win7 was made from inside vista - or is the screenshot from the Vista install ?

Hello Nigel, as K: is "Boot" that was sniped in Windows 7.

Yes Ted, That's what is a little worrying, Hopefully the start-up repair will either sort out the non standard drive designation or will allow the running as k:

This could of course cause issues in future for any applications that incorrectly hard wire the registry to point to a program or .dll on c:

That's a valid point as I hadn't considered why, if K: is boot and it's in W_7 why it's not listed as C: and Vista something else.

Indeed, it seems to be quite simple to have to OS partition as one besides C.

EDIT: reading the above post, I wonder, could you not make a work around for the problems the two of you describe.

Hi Ted,

I've seen it before, if you install a new OS from within an old one (like one of the special "upgrades" that were suggested when win7 first appeared), then when the drive is set-up before the first reboot during install the c: drive is still active and so the installer has to use another drive letter.
