Solved Incorrectly Partitioned Disks after reinstall

[Infinite]

So I had to reinstall my Operating System due to problems I could not solve, and due to the lack of backup.

I reinstalled Windows 7 to a different drive from my old drive.

For some reason my C:// drive is not the drive I am using now, and the A:// drive is the one that I currently am using.

What I want to do:
- Make the current drive (A) as Drive C.
- Be able to delete the current Drive C.
- Use the deleted partition for Data.
- Be able to boot Drive A - hopefully C:// after.



Any suggestions?

You're stuck with it. Far too difficult to change the os registry letter.

It doesn't matter, it will work fine whatever letter it is.

If it really worries you, you will need to reinstall either by booting the dvd, or by applying image from the wim.

Is there any way to remove the old installation at all?

I dislike having to choose which Operating System to use at boot.
I'd like to be able to use the other drive for backup and data.

If you are desperate for your new install to be C:

Boot the 7 install media , format the C and A partitions. Mark whichever you are going to install onto Active. Mark any others Inactive.

OR

If you don't mind keeping the one you have as A :

Open elev cmd ,

bcdboot a:\windows /s a:

diskpart
sel vol c
inact
sel vol a
act
exi

Close cmd prompt.

reboot

Always unplug all other HD's during Clean Reinstall.

And always boot the installer as running it from the old OS blocks the C drive letter from use for the new install. How to Boot your Computer from a Bootable CD or DVD

Okay, so I've done a few things;



I am currently using Drive C, the only thing I need to do is make it System/Active I believe?

 

[SIW2]

Yes.

diskpart
sel vol c
act
sel vol d
inact
exi

bcdboot c:\windows /s c:

reboot

Thanks, exactly what I wanted. I would give some reputation but I need to spread some around.

Glad you got it sorted.

Are System Active Boot flags on C now?

Reboot and tap the F8 key to see if Repair My Computer is still on Advanced Boot Options.
If not and you want it run Startup Repair - Run up to 3 Separate Times which is preferred for moving the System flag for this reason.

Okay, I found another problem;
When I start Windows, there are 3 operating system options;


Judging from my updated Disk Management preferences, I believe this is invalid;


I still haven't tried the suggestions gregrocker mentioned, maybe that will fix the issue?

You didn't follow the steps I gave you for unplugging the other HD and booting the installer when you reinstalled? These are the most fundamental rules for doing a Clean Install Windows 7, followed by deleting all partitions during install to create New.

It appears you only have one OS now though so enter msconfig>Boot to remove any ghost listings. If not listed there install EasyBCD (click Download - no Name or Email required) to delete the ghost listings on Edit OS Menu tab.

You might also be able to sort this out by running Startup Repair a few times, especially if you transferred the boot files to C using any method besides Startup Repair - Run up to 3 Separate Times the link to Repair My Computer on F8 was most likely lost.

They are just boot menu entries. Open msconfig>Boot tab >Delete any you don't want.

Okay thanks, everything works, I also used the Startup Repair tool and all seems good.
