Help with dual boot system.

I have partitioned my C:/ drive with a Vista OS and created a new partition on this drive and installed Windows 7.

Now all is well with my new Windows 7 OS and I want to remove the Vista OS and end up with one partition.

I am not sure what to do and want to make sure I don't damage the Windows 7 OS, it was quite a learning experience and involved many hours.

A few screen shots that might help.

This is just a personal view, but I would be inclined to carry out another clean install of Windows 7.

This will enable you to wipe Drive 0 clean and create a fresh partition for Windows 7 at the start of the drive.

The installer will create a 100MB System Reserved partition for the master boot record leaving you to decide how to partition the rest of the drive, if indeed you want more than one partition on it.

Doing it this way gets rid of Vista and its boot record and is in my view the simplest way of achieving what you want.

If you go down this route you might want to disconnect the active Drive 1 first, and then reconnect it when you've re-installed Windows 7.

On the other hand, as you are conversant with Partition Wizard you can boot into it (if you have burned the ISO to a blank disk) and delete your Vista partition then extend the Seven partition to the left.

Having done that you need to boot back into Windows and run a Startup Repair three times with a reboot after each one.

Startup Repair

This keeps Windows Seven intact so you wouldn't have to reinstall it.

I agree, since you now know how to install Windows 7 I would delete the partitions and install again.

Then again, maybe you should wait a bit since you put a lot of work into it. Once you feel your ready, reinstall.

But don`t bother doing any updates if your gonna reinstall.

First boot free Partition Wizard bootable CD, rightclick on Win7 partition to Modify>Set to Active, click OK.

Next rightclick on Vista partition, select Modify>Set to Inactive, OK. Do the same for E if it is a data partition as only OS partition should be marked Active.

Next click on Win7 HD again to highlight it, from Disk tab select Rebuild MBR, OK, Apply all steps, reboot.

If Win7 starts on its own then you don't need to run Startup Repair 3 Separate Times
from the Win7 DVD or Repair CD, which writes the System boot files to Active partition. Rebuild MBR will sometimes suffice by itself - if not run Repairs until it starts at reboot.

Once Win7 starts on its own, save a backup image externally. We have never had a failure with PW CD in hundreds of these operations we've helped with here but back up still needs to be done now that Vista won't tag along. Backup Complete Computer - Create an Image Backup

Next boot PW CD, rightclick on Vista partition to Delete, OK. Then rightclick Win7 partition to select Resize, drag left grey border all the way to the left over the deleted Unallocated Space, OK, Apply all steps.

If resizing causes Win7 to fail to boot, run Startup Repair until it starts again.

Reinstall everything, I think not.

You make reinstalling sound so easy, it is not.

Just consider Photoshop CS5 and all that is involved. After the reinstall is finished I need to find and move the custom settings for, brushes, actions, custom desktops, etc,. Then I have to reinstall any plug-ins and find and move any customs setting for the plug-ins. Now include Lightroom, its plug-ins and their custom settings. On and on it goes and I want to avoid the days of work and the possibility of missing something important.

Can I just format the partition that contains the Vista OS and change the boot file to not include Vista? I have never done this and need some confirmation that I am not about to screw up in a big way.

I can see where you are coming from and I'm sorry if it sounded too simplistic.

Please follow the excellent advice in gregrocker's reply and you won't have to reinstall Windows 7.

Partition Wizard's bootable CD is a great tool for problems such as this and we can help you at every step.

Install from ISO file!!

Did I mention I installed Windows 7 Professional from a ISO file, does it matter. My son is taking a computer class at the local collage and the tuition included 4 license keys. I downloaded the ISO file and burned it to a DVD for the install.

Boot the DVD, on the second screen should be a Repair My Computer console to access for doing any needed Repairs.

It scans the OS to discover installed OS and see if repairs are needed, then offers you these options: System Recovery Options

Almost Done

Thanks Gregrocker, I followed your instruction with only a few questions.

These images are digital photos and that is why they are blurry.

Partition Wizard did not work exactly as you said, probably my bad.

-windows-7_pw-1.jpg

I set the Windows 7 to active but the Vista partition must have been already set to inactive because this option was grayed out. Also I was not able to select to rebuild the MBR, grayed out, on the Windows 7 disk.

-windows-7_pw-2.jpg

When rebooting I was informed I am missing NTLDR, whatever that was. After running three, just like you said, Startup Repairs, I was able to boot.

-windows-7-ntldr.jpg

Now my only issue is how to eliminate this screen.

As soon as I am able to remove the OS selection screen I am done.

Thanks again, Floyd

edit: I also created the system backup, thanks for good insurance advice.
