Windows 7 - Delete the XP partition

Hello,

I'm a new user of windows7. I have XP installed on a partition (20GB) and i've installed last week Windows 7 in the other partition (140 GB). Now i want to delete the XP partition and expand my Windows 7 partition, but when i try to delete the partition with XP on it under Windows 7 it gives me a message that i cannot delete the partition. What is the problem and how i can solve my problems?
P.S. Sorry if this problem was posted before but i'm new also on this forum.

Go into MSconfig and delete the XP entry, then go to disk management and delete the partition and expand your Windows 7 into the free space.

I think it will not let you because the boot info is still there. Go to MSconfig and delete the entry first. It should work.

You may have to use this after if it does not boot

Hi sergiu & welcome to SF
Can you post a screenshot of your disk management please?

Start Menu > Right Click Computer > Click manage (accept the UAC prompt) > Under Storage click Disk management and take a screenie of that.

Here it is.
Where is the XP entry? i can't find it

Disk mangement cannot move to the left. That's why you can't delete the 20GB partition.
If you installed XP in the 20GB partition then XP is in D:
There are 2 options.
Either boot off of your 7 DVD and clean install 7 over XP in D:. You'll then be able to format C: and extend D: over C:
Or you can see this thread, i think it's relevant to you

what thread?

Have you had any luck in "deleting" that partition? I HOPE so! IF so, please share with me what you did.
I have been trying to do something very similar....I am using W'7 RC 7100 and the HD has been partitioned into 3 and one partition [SYSTEM] has W' Vista on it [which is unuseable], I want it OFF of the HD before I use W'7 UPGRADE disc...........I have used MSCONFIG to take W'Vista OFF of the dual boot....but Disk Manager will NOT allow me to re-format or delete that partition. My "C" partition is the BOOT drive and has W'7 RC on it.
PLEASE help me if you can --- I want to do the UPGRADE install of the NEW W'7 Upgrade disc.

TKS michael

Sorry sergiu, i didn't realise i forgot the link to the thread LOL!

Partitioning Trouble

Thanks for providing that thread which is in itself a tutorial on moving 7 over onto deleted XP partition.

We have helped a dozen guys do this here since release date and each one is a headache.

Amazing how fast people want to bail out of XP, get it off their machine!

In Summary:

You need to use a free Partition Manager like Partition Wizard bootable.

Delete XP, mark the 7 partition active, copy it over onto the XP unallocated space. (if XP is larger, you need to shrink it before copying), delete original Windows 7 partition

Run startup repair 3 times until it takes.

10x everybody :P
