Solved Delete one of two Partitions with windows 7

April 6, 2012 at 00:18:59
Specs: Windows 7, IntelQuadcore 2.8 GHz

Was unable to update my win7 64bit OS due to a wrong driver. Received many BSDs and tried to find out which driver. Something to do with "kernel"> Bought Driver Genius 11, found 34 wrong drivers, but could only set right two. SP1 download failed. Suddenly could not find my Freecell any more. All my back-ups turned out to be unusable. Time for a re-install I thought.

Found there was some 80 GB unallocated space before the old OS, so decided to install a new OS there. Intend to delete the partition with the defective OS and put a trial Win8 on it.

New OS is now in place and seems to be without problems. When I start now, I get a menu with twice Win 7 on it. The first is the new one I found.

Can I now just formatthe defective partition and install the trial Win 8 on it? Will the startup menu now show Win 7 and Win 8 ?

This may help....lets say we have a 500g hard drive, brand new nothing on it. When you install vista, win7 or win8, they create 2 partitions, one small (100megabyte or so) for the boot loader and then installs windows on the 2nd large partition, giving you most of your 500g drive.

✔ Best Answer

To dual boot using the above example: remember by default windows is going to create the small bootloader partition, so when installing and Windows shows the size of the current partitions we'd make the 2nd large partition say 200g instead of the full size. so at this point Windows will create the boot loader partition and begin the install on the 200g partition you create. windows 7 installs and you then put in the drivers etc for win 7. Now you can Install Win 8, it will automatically change the bootloader partition to incorporate windows 8, and ask where to install win8, so you create another partition using the leftover space (200-250g or so) of this 500g example. Win 8 install to this new partition and when all is said and done, windows will boot up to a menu asking you to select win 7 or win 8. You would now have 3 partitions in total. 1 boot loader, 2 Windows 7, and 3 Windows 8.
Personally, I'd do a hard drive diagnostic to make sure the hard drive is not failing causing some of the issue you describe. You find the make of the hard drive (western digital/seagate) what have you, go to their website and download the ISO to make a bootable diagnostic cd.....boot to the cd you create and do a long test of the drive. It makes no sense installing on a defective drive, so I always test the drive first before going to all the trouble of installing operating systems.

It is always best to install Windows in the Order they came to market. If you install Windows 8 first and then attempt to put 7 on, you will run into problems. That is why you install 7 first and then 8. Once you have Windows 7 would boot into windows 7 and place the Windows 8 disc in the dvd and begin a custom install.......that begins the setup process and eventually you will get to the point of selecting where to install it, and you make the 3rd partition. Order of operations is important. Hope this helps.

To sum up from where I think you are. You have 3 partitions. 1 boot loader, 2 Windows 7, 3 windows 7. If the win 7 on partion 2 is the functioning one then you could delete the 3 partition and install win 8 on it. Remember to load into windows 7 and put the Win 8 disk in, if you just boot to the win 8 cd and begin the install you will get a different result. As mentioned I'd still test the hard drive before I went to all the trouble.

Somewhere on this site there is a step by step, "how to" for dual booting I highly suggest you read it.

The long weekend is here..............wish you well.

I am thinking when you delete the 3rd partition, you'll find the computer no longer boots back into windows 7 without modifying the boot, but I may be wrong.....if it does great.

Once should be getting the drivers from 1) the maker website Dell, HP whoever for your model and operating system pay attention to whether you have 32 bit versions or 64bit versions. I have little faith in programs such as you purchased. 2. If this is a custom made computer then one would pull off the side panel and find the make/model of the motherboard and go to their website for the latest greatest drivers for your operating system. If the graphics card, sound etc are separate.....then one would find the make/model of those and go to their website for the latest greatest from the actual makers/supporters of the product. PS if you are one those folks who loves the Registry Mechanics, and RegCures.....etc registry cleaning programs......stop, you may end up with more blue screens than you started with.

Wonder if that 80Gig was a very important place that saved your OEM data?

Meanwhile I am now with 3 partitions on one harddisk, looking at them with Partition Wizard 7 ( they are:

1. C: 86.48GB Primary System with Win7
2. D: 60 GB Primary Active&Boot with Win8
3. E:Data 319.28 GB Logical

I now get a Win8 choice menu as to which OS I want to use. Have looked at Win 8 and found that it did not have any advantages compared to Win7. I do not have a tablet with touchscreen.

So now I want to undo/delete Win8. How do I go about without loosing my Win7 ?

Delete the D: partition with Partition Manager 7 and use it's "rebuild MBR" or otherwise ?

Forgot to mention that I have a P7P55D LE motherboard and downloaded the latest drivers for this motherboard from Asus to put my Win7 OS in order.

If you have your Windows 7 install disk, you can use that to do a Start Up repair which will rebuild your MBR. If you use the feature (in the back up section of Windows 7) to make a Windows 7 Repair Disk, you can use that to do the Start Up Repair as well (a good tool to have).
I have found that Disk Manager in Windows 7 can do just about all I need to do with partitioning and formatting.
Remember that there is always a danger when you partition and format so make sure you back up your files first to an external drive (or a separate hard drive that can be unplugged).

You have to be a little bit crazy to keep you from going insane.

Correct, unless you have a tablet or touch screen, Win 8 is a pretty useless upgrade.
