Windows 7: Remove XP and Win 7 Dual boot on separate drives

Hi All,
Being a newbie to this forum, I am sure this question has been asked before, but I still need to ask the question anyway:-)
I have a laptop with two 350Gb Hard drives installed.
XP was the original OS loaded on the (C) drive and I recently loaded Win 7 (32bit) on the (D) drive with the dual boot option.
I now have no further use for XP, as I am using Win 7 only, and so I want to delete\remove\re-format the (C) drive so that I only have a Win 7 OS.
Is it possible to remove XP without having to reformat both the hard drives, and thereby losing all my installed programs on the (D) drive, or can I reformat the (C) drive only, without making changes to the (D) drive?
If it helps, I have attached a screen dump of the Drive Management map.
Any help/explanations or pointing me in the right direction will be appreciated.

Hi phrozen

Welcome to Seven Forums
Have a look at this Seven Forums thread

Hope this helps and regards

Boot into XP to mark Windows 7 active in Disk Mgmt, power down to Unplug the XP HD, set the Windows 7 HD as first HD to boot in BIOS setup,

Next boot the Windows 7 DVD Repair console or Repair CD, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots to repair or rewrite the MBR until Windows 7 starts on its own.

You should then be able to plug back in the XP HD to format it in Disk Mgmt. If not, boot the Windows 7 DVD Repair/Repair CD to clean that HD using DISKPART: Disk - Clean and Clean All with Diskpart Command

Might help to mark 7 partition active first.

OP says he has Windows 7 on D which is already System Active.

Apparently he is quoting drive letters as viewed from XP, when the screenshot is from Windows 7 relative view.

Windows 7 is on C in that screenshot.

Yes, he will need to mark 7 partition active and create the boot critical files. A few runs of startup repair will do the latter.

OK I see now that he's using Windows 7 Disk Mgmt which is viewing C relatively. He must have posted drive letters as read from XP. Confusing.

OP: If this is the case, you will want to go into XP Disk Management to mark Windows 7 active,

Power down to unplug XP HD,

Restart into BIOS setup to set Windows 7 HD as first HD to boot (after DVD drive),

then boot the Windows 7 DVD repair console, click through to Recovery Tools list to run Startup Repair up to 3 separate times with reboots until Windows 7 starts on its own.

You can then power down, plug back in XP HD to format it, or if it interferes run Clean all from Windows 7 DVD/CD as given earlier.
