Windows 7: Extending Windows 7 partition?

Extending Windows 7 partition?

Hello,
I would like to extend my Windows 7 partition to take up the remaining space on the drive that I've got the Win 7 partition on (currently 100GB unallocated).

I've read some tutorials and tried method two where it has me try to do it with an elevated command prompt, however that didn't work. The first time I tried it, it said that it worked but it never really did, and when I tried it a second time it told me there was no space to allocate.

Anyway, my system is divided like this:
C:\ holds my Vista installation
E:\ is partitioned into 3 drives, one of them being the Win 7 drive and 100GB of unallocated space.

When I use disk management in Vista, and right click on the Win 7 partition to extend it, it's grayed out so I can't do it that way. That is why I tried it with the elevated command prompt.

I also read the suggestion to use Partition Wizard, so I burned it to a bootable disk and rebooted into partition wizard, however as soon as it starts it gives me a big warning that says if I resize or whatever a partition that has Windows 7 on it, then I will no longer be able to boot into that partition/drive.

So I am stumped.

Here is a snapshot of disk management to help you understand what I've got, and hopefully somebody can help me so that I can extend the 40GB windows 7 partition to become a 140GB partition:

When I read the warning, what I took away from it was that if I tried to extend the win 7 partition into the unallocated space then windows 7 would no longer boot. I would like to avoid this as it's all setup nicely and I don't want to have to reinstall it and everything else.

I personally tend to use Acronis Disk Director for my partitioning tasks. It costs a little bit, but its the best and most reliable partitioning tool I've ever used.

As for the warning about being unable to boot up Windows 7 (this would apply to Vista as well, btw), mosto f the time you can fix that by booting from your Windows 7 installation disk, click on Repair rather than Install, and have it fix your startup/boot manager. It sometimes takes a couple of tries, but I've always had it it fix my bootloader in the end; my bootloader usually gets screwed up when I do an OS re-install on a new partition and then delete the old one afterm oving my data over. The WIndows isntall disk's Startup repair usually fixes it.

The reason that you cannot extend the partition within Windows is that you can only extend drives to the right. It has to be space to expand into past the end of the current drive.

You can use something like gparted to first move your Windows 7 partition to the left and then extend into the free space available on the right. It will take some time if you have stuff on the drive though.

On my box at home, I got rid of my 150GB partition at the start of a 1TB drive (which used to hold my OS). I wanted to turn the 1TB drive into 1 big partition just for storage. Even though I had less than 100GB of stuff on it (which I should have just copied to an external USB drive in retrospect), it took about 7-9 hours to complete. In the end, it all worked perfectly though.

Hi all

Quick and easy way (around 30 - 60 mins).


1) Create bootable restore CD of Acronis TI / Ghost / other Disk imaging software.

2) Backup OS partition with Acronis TI.

3) backup data on adjacent partition with TI.

4) Delete OS and adjacent partitions.

5) Boot restorable bootable media with your Acronis TI program on it.

6) Restore OS to re-sized partition - TI will prompt you for the size you want to make it.

6) Boot restored OS.

7) create new partition (via Windows) to restore your data.

8) Restore data with Acronis TI.

Job done.


(Use external USB / network drive for storing backup data - the Acronis TI has all the USB / network drivers even when using the bootable restore disk).

Note also the bootable Acronis program will allow you to delete partitions so you don't need to fiddle around with GPARTED for this type of job.

Cheers

Okay. Thanks for the clear instructions Jimbo, I am now downloading the trial for Acronis TI and will give it a go.

Duh, never mind. I do step 2 from the bootable cd.

jimbo45s advice can also be applied but using WinPE w/ imagex instead of acronis.

Just another way to accomplish it.

Okay,

Well I *almost* got it right (even though almost only matters in hand grenades and horse shoes).

I created a system partition backup.

I deleted the original B partition, and extended the new M partition to encompass both it's own 100GB partition and the old B partition's 40GB.

I restored the backup. However, I was confused when it comes to restoring the MBR and what drive I was supposed to put that on.

I ended up putting it on the E:\ drive since that is where the partition is that I restored. However now when I start the computer I no longer see the dual boot screen that used to let me boot into Win 7 or Vista, now it just directly boots into Vista.

I was concerned about restoring the MBR to my real C:\ drive (as that's where vista is installed) and was concerned if I do that then the computer won't boot up at all.

So, once again, I am stuck, all the restored data is now on my new larger partition, but apparently I no longer have the dual boot.

I just figured that when making the backup, it wouldn't pull the MBR from the C drive, but Im guessing that I'm wrong, so before I try to restore it again, and this time put the MBR on the C:\ drive I want to ask if that is the correct thing to do or is that going to wipe out my system and make it non bootable from the HDD?

Thanks,
