Windows 7: deleting OS and canceling dual boot

Hello,
I need help with deleting OS and canceling dual boot,

previous state:
251 MB primary
C: win media center / system, active, primary /
D: win xp / extended, logical /
E: dvd drive

I've formatted D: and it has become unallocated, my dvd drive got new number D:
because I couldnt use my dvd drive to run installation dvd of Windows 7 / I got error code 0x80070017 which is about corrupt dvd or something / I have copied it to C: and did run setup.exe.
It has asked me where to put it and I chose that unallocated space. Now after installation everything works fine,

and it looks like:
251 MB primary
C: win media center / system, active, primary /
D: dvd drive
E: Windows 7 / boot, paging file, logical, state failure in the system /


Start-Run-MSConfig in boot tab is: Windows7 (E:\Windows): Current OS, Default OS, nothing else.
Windows 7 has created Windows.old file but I have deleted it.
at the start up I get a page for 30 sec to choose from Previous OS and Windows 7, I know I can disable it to appear again going to Start - control panel - system - advanced - start and restore...

But I want to know how to delete OS from C:, whether it can be done safely, because E: Windows 7 is not primary only logical, how to get rid Win Media Centre for good and keep Windows 7 as the only OS .

Thanks for your ideas. Nika


Hello guys,
did some research here and I have found Partition : Recover Space Used by an Older OS by Bare Foot Kid.



Can I use this tutorial to solve my problem?

Where did you get Windows 7? Burn another DVD at 4x speed using ImgBurn. You need to be able to boot it to install or for repairs.

I would wipe the HD of all code to clean reinstall Windows 7 since you now want to use only Windows 7 and it installed to a failed state on the Logical, probably because it couldn't place its boot files correctly on C. SSD / HDD : Optimize for Windows Reinstallation

If you want to try to keep it, then back up your files, boot free Partition Wizard bootable CD, rightclick C to delete, OK, rightclick Windows 7 to Modify>Convert to Primary, OK, then rightclick Windows 7 to Modify>Set to Active. Then rightclick Windows 7 to resize into deleted C space if you want, OK, Apply all steps. Free Download Magic Partition Manager Software - Partition Wizard Online

Next boot the Windows 7 DVD Repair console or Repair Cd to run Startup Repair up to 3 separate times with reboots: Startup Repair - Run 3 Separate Times

Hello,

so I have downloaded the file, burnt iso, and run. But in partition wizard, my 70GB of E: where Windows 7 was supposed to be, was unallocated disk space, so I had to create one modify set to primary and set it active.

it was strange because in windows disk manager was C: xp media center and E: Windows 7, / D: dvd drive /

I am now confused why Windows and Partition Wizard have reported different things.
By the way I have deleted C: in Partition Wizard and lost all my data. Because there was not any OS on E: I had to do clean install which was smooth without any error codes.

I am not happy about lost data, is there any way to recover them?
But overall this was very valuable experience.
Thanks for help. Nika

Always back up your data before doing any repartitioning or installation.

Try Recuva Data Recovery to scan the HD to see if it can recover your data.

If not, I would wipe the HD as suggested first before reinstalling. Here are tips for getting a perfect install: re-install windows 7
