I was told to reformat my computer because it was constantly crashing and I was told the errors were something that could be fixed by doing this. So I put in windows 7 disk and had a few problems installing it the first time. In the end I ended up installing it twice, once on the D drive and once on the C drive and when I boot up my computer it will go to a screen before windows that asks me to choose which Os i want to use showing 2 choices which are both Windows 7. Is this a huge problem or is it something I can just leave be? Here's a shot of my disk management screen:

Here is the procedure on how to properly remove one of the installations: http://www.sevenforums.com/tut.....te-os.html

This can normally be cured with MSconfig file and clicking on Boot Tab.
There should be TWO Boot entries shown.
Delete the one that is NOT Default, Close all and Reboot.

If that doesn't work, we'll use BCDEDIT Commands.

Rick, that does not work - I have tried it. You will still get the choice of 2 systems even if you removed one BCD from the bootmgr. You have to also cleanup the MBR.

@whs,

Yeah I know so that's why my last sentence above says:

"If that doesn't work, we'll use BCDEDIT Commands."

OP had trouble even installing Windows so recommend a Book rather than EasyBCD program with old tutorial OR me walking through BCDEdit Commands.

That's why I linked the tutorial that I had made for the purpose. Don't you think that would be enough guidance ?

If you really want to do it right then download Partition wizard from here http://www.partitionwizard.com.....nager.html
Then format both drives > then set your "C" drive as your active partition.
Now when you start to install your O/S again skip the page that asks if you want windows to format your HDD. If you allow this step you will end up with the sometimes troublesome 100mb partition with your boot files.

So I was looking through those tutorials and it seems they all start off by having you find the drive that is labeled as "Active" in the disk management screen but in mine neither of the drives are labeled as active. Is this an additional problem?

Here is another picture showing the statuses of both drives: http://imageshack.us/photo/my-.....52181.png/

Edit: I also just realized that under my computer the C drive does not show up at all. Is this a result of Windows 7 being on the wrong drive? Here is a picture of that: http://imageshack.us/photo/my-.....85774.png/

Hmm, from your second picture it is obvious that D is the active partition (the little flag). But why does D not show in Disk Management - very mysterious.

I thought that was a little strange, well its a brand new computer and is still under warranty so they said I could send it back and have them take a look at it. I will update the post when I find out what's going on. Thank you all for your help :)

You just have a couple of entries in the boot manager pointing to the same drive is all.

Best just do a Clean Install using this tutorial.

You can do it with your Installation DVD.

Just be sure to use the DiskPart [ SHIFT + F10 ] procedure to wipe the HD first.

The Command Prompt Window Picture is Wrong.

It will say X:\Sources_

I tried but the problem is when I put my installation DVD in and start it up before it can even start installing this error pops up: http://imageshack.us/photo/my-.....49997.png/

Don't think your HDD's are cleaned to accept installing an O/S.
Have you formatted both drives as suggested above or are you trying to do an install over your existing O/S?

You know, If you would have two os's on one machine..... (As in two win7s)
1: You could have one as a profile.
2: You might get a virus on one of the copies but it won't get to the other. (Backup OS?)
3: Use them both and set them to both have their max profiles (Twice the profiles!)
4: Testing purposes for one of the copies.
5: One copy for work and the other copy for home
6: Have two versions of win7 on the same machine, what you could do then is copy things from a version that has things your main edition doesnt have
Into your main Version. (e.g. Enterprise and ultimate on one machine.)

germ-x I have just been putting the windows 7 format disk in and running it with windows 7 still installed. I thought that reformated the drive on its own, and then installed windows 7. I will try formatting the drives and then using the disk. Thank you, I'll try that and give an update afterwards.

Following the guide Raphoenix posted I'm a little confused at the beginning. If I do still have my windows 7 installation disk do I still need to use Rufus to “Quick Format, Create a bootable disk using: ISO Image, and Create Extended label and icon files.” and do I also still use Rufus to copy the Windows 7 files from the ISO to the USB? Or are those steps for installing new Windows 7 files if you do not have the original Windows 7 disk? I'm sorry, I am not fantastic with this type of stuff so I apologize if my question sounds confusing. Thank you again every one who has been trying to help, I really appreciate it.

lukycharms621,
If yo uuse Partition wizard it is a lot less confusing and easier to use.
You download > burn to a Cd > change your boot order so your optical device is your first boot order > then boot your system and make your changes.

Thanks germ-x, I will try that. Sorry again if this is a stupid question but so you're saying that partition wizard is a lot less confusing and easier to use that Rufus? Or do i still need to use that program as well?

Partition wizard is in a Windows GUI format so it makes it a lot easier to understand. Once you format and if you want you can also partition your HDD all at once. You are then completed and do not have to use any other utility.

It gets no simpler than this:

To format your hard disk during Windows 7 installation, you'll need to start, or boot,
your computer using the Windows 7 installation disc.

1. Turn on your computer so that Windows starts normally, insert the Windows 7 installation disc,
and then shut down your computer.

2. Restart your computer.

3. Press any key when prompted, and then follow the instructions that appear.

4. On the Install Windows page, enter your language and other preferences, and then click Next.

5. On the Please read the license terms page, click I accept the license terms, and then click Next.

6. On the Which type of installation do you want? page, click (Custom).

7. On the Where do you want to install Windows? page, click Drive options (Advanced).

8. Click the Partition that you want to change, click the Formatting Option you want to perform,
and then follow the instructions.

9. When you've finished formatting, click Next.

10. Follow the instructions to finish installing Windows 7, which include naming your computer
and setting up the first user account.

Copied from MS and made simpler.

@Rick,
This has been a sore topic for many moons and countless posts for help. If you allow Windows install disk to do the formatting and partitioning you will end up with the 100mb partition which eventually leads many to have that "Missing Boot Mgr error".
With the OP having the O/S installed on 2 drives it might be best to work outside windows environment. That is accomplished with Partition wizard not to mention several other bootable partition utilities

@Tom,

I know but OP really has only a (1) HDD machine with the Boot Manager messed up.

See this picture in the OP's first posting on this topic thread.

Since OP has low knowledge of Windows, best to get system installed even with the 100MB partition which I despise as much as you.

NO reflection on OP as many have never installed Windows before.

Would be useless for me to try to walk through BCDEDIT or Diskpart Commands to fix the the machine.

Best to do just a MS Install until OP understands Windows better.

What do you think ??

Seeing that I can't see any "C" drive I would agree the OP has to start from scratch. I don't understand how Windows installed 2x on the same partition of the same drive.

Have to understand the entries in the boot manager.

MS Technet does a poor job of explaining the subject, best to get books. :)
