View Full Version : Remove windows7 on dual boot

01-02-2014, 11:06 AM

I was previously using windows 7 and installed windows 8 on a different partition, lettīg windows 8 installing the dual boot.

I ve tried to remove the windows 7 partition with both easeus and the windows tool with no luck
The windowd 7 partition is the primary partition and any tool (windows or easeus) will allow me to format it or delete it.
The windows 8 partition is the boot partition. I cant change it to primary partition.

Btw, i have remove the boot option (using msconfig) and currently boot directly on w8 (no more boot option).

I believe my partition is mbr.

Any idea how to proceed ?

Only a maximum 3 primary partitions can be created on MBR disks. You need to convert one of the partitions to logical partition before you can create another primary partition.

Hello again badrobot,

Easeus won t let me transform the windows 7 prmary partition to a logical partition (i could then easily delete it).
I tried also with the windows disk manager, it doesn t work...this is my issue

Are you wanting to keep the windows 7 OS at all. If not, I would just delete the 8 partition then do a clean install of 8 making sure to format the HDD thus have a clean/formatted HDD with just windows 8.

I don t want to keep Windows 7
I have two softwares that must be activated for each installation.
I have just installed them on my w8 partition and don t want to go through the whole installation process again, incl. For these specific sofwares.

Thanks for your suggestion anyway

WELL, I'd do things a bit differently.

I'd do a backup of my Win 8 partition, to some removable media, like an external hard drive, or DVD's.

Then I'd totally wipe the main hard drive clean and set one partition and format it, NTFS.

Then I'd restore my backup Image to the clean Hard drive.

Later, if you want to, you could run a Partition Manager and create a second partition for 'Storage'.

You wind up with a nice clean hard drive, with just Windows 8 on it, and nothing else.

Cheers Mates!

Or you could do an upgrade to your system while trying to run just Windows 8 on it, Get an SSD as boot drive (there are so many price cuts right now for 128GB under $100 so take advantage of it) and clone windows 8 on it (use free Macrium Reflect for cloning). Then format the other hard drive and use it as data drive. You have plenty of options. You just need to invest a few$ on some suggestions.

badrobot's suggestion as to Macrium Reflect worked for me when I cloned Windows 8 on my Dell from a 1TB HDD to a 120GB SSD. Fired right up w/out the need to reboot afterwards! Speaking of SSD's, the deals are hotter now than when I bought mine. Had I waited a bit, there was a chance to get a Crucial M500 240GB for $129. Hey, but I'm not complaining, the SSD that I have scores a perfect 7.9 on the WEI.

However, Windows 8 is no longer on the PC, I had an OEM copy of Windows 7 Home Premium, that was installed & activated, then backed up. After updating, I used my Windows Anytime Upgrade key to make it 7 Pro. It can be moved to another computer as long as it's removed from the old one. In my case, the old one is dead.

Patator, does this issue have anything to do with your other thread?

I have done this very same thing in the past. First off, I made a backup image of the entire drive. Macrium Reflect free is perfect for this. Then go into msconfig from Windows 8, make it the first bootable partition. Then delete the Windows 7 entry & reboot (After re-reading,I now see you've done this part). If all is fine, format the Windows 7 partition with a bootable CD of Mini Tool Partition Wizard. The link to the bootable CD is on the left side of the link below.


Reboot with that same CD & then move the Windows 8 partition over to the empty space where Windows 7 is removed from. Just slide it over, click OK, then Apply. Again, make sure to backup before doing anything. Too, make sure that you have your install/repair DVD of Windows 8 on hand, as it may be needed. Hopefully it won't be needed, but sometimes it is.

That should be all you need to do, I've done this many times when setting up a dual boot & wanted to get rid of the 1st one. I take it that you do have the 100MB System partition in the 1st position?


Hey Cat, those Crucial SSDs will be on sale over the weekend on one of the stores I buy most of my stuffs. But with exchange rate and all, I think it's also around $129. :)

badrobot, the 240GB is worth the splurge, as long as you like the Crucial brand. Unlike Intel & Samsung, there are no toolboxes or other tuning software, but really one can do this themselves. My 1st SSD was a Crucial 128GB M4 that's still running strong.

Next time, I won't bite on a Good Friday sale, unless it's a rarely promoted item.

Again, I'm not complaining, I'm happy with the 120GB 840 EVO. Am using only 35.5GB out of 100.5GB (the rest went to Samsung's recommended 10% over provisioning). Plus I have Rapid Mode enabled, somehow, it forces things more into RAM, giving me more speed.


There was a promo on their 840 EVO 750GB for $279 recently.

Anyway, being one who figures things out, you can make the Crucial just as fast. Plus I believe the M500 models carry a 5 year warranty.


Cat, it's very tempting but I don't see myself getting more than 250GB as I hardly use up a 120GB. I have 250GB on my Win 7 and 128GB on Win 8.1 HTPC, and another 128GB on my laptop now running Linux. My win 8.1 tablet is running on built-in 32GB SSD. Plus I like to keep data drive separate and I don't need an SSD for that and I am using the original 1TBs on each of my machines. I still have that 500GB WD Black available and I also just recently got a 128GB USB 3.0 flashdrive as an external drive for my win 8.1 tablet. I was thinking of getting another 128GB SSD for my tablet because I have a spare Vantech USB 3.0 2.5" enclosure but I saw a PNY 128GB USB 3.0 flashdrive on sale for $49.


I hope the OP will get his problem sorted out soon. Patator if you need help with cloning or backing up just let us know.

Thanks to all for your help.

To answer Cat, this thread is not related to the safe mode not working on the pc of my wife (Asus Vivobook S500C).
It's related to my Asus U30S. I have upgraded both PC last week to SSD drives (Sandisk Extreme II 240Go and 480Go...excellent deal)

I will restore my sdd hard drive to my former 7200 rpm hard drive and run the tests from it.
I will try first Cat solution using Gparted to remove the windows 7 data and move the windows 8 partition over it.
If it doesn t go fine, I will use TM solution (full format and restore - using Acronis True Image 2014 - my regular backup system).

I will let you know how it goes

So why is this thread locked?

thanks to all of you for your help.
I have used cat's solution + repair function from a windows boot pendrive (ntdlr was missing after the windows 7 formating).
Minitool Partition is a great tool !

thanks again
