Cannot make large enough partition for dual boot.

Been trying to dual boot win8 on to my laptop. While trying to make a partition on the hd i'm not able to make one of sufficient size. I have plenty of room left on the hd but it won't let me go over 39mb.

Any ideas how to solve this?

Any questions, just gimme a shout

Screenshot included.

Try either Partition or Volume - Shrink or the option three of the tutorial Partition Wizard : Use the Bootable CD ; it works for shrinking from the either side.

If still troubles, you may go for a defragment first.

The problem you're faced with is this: You already have three primary partitions and a logical partition D, which happens to be part of the extended C drive.

If it were me, I'd first make sure I've created a set of Lenovo recovery discs so that I have a way of getting the computer back to its factory state if need be.

I would then delete the 29Gb D drive and the 15Gb OEM partition, shrink your C drive to suit, and then create another primary partition for Windows 8.

Do not delete the System Reserved partition because that has the Active flag and will hold the boot files for your dual-boot setup.

If you try and create another primary partition on your current drive structure you run the risk of converting the drive to a dynamic drive and that would cause you problems.

Thanks for the response. I'm in the process of making the recovery discs now. I don't suppose you know what is on the 15Gb OEM partition? I'd like to know what I'm about to delete before i delete it. As for the "D" drive, I never saw the point of it in the first place, they could've put the driver, that were stored there, into a folder on "C". So in your opinion deleting those 2 partitions shouldn't cause any problems?

Apparently, it's all to do with Lenovo's factory restore.

What may be a better idea before you delete it, is to create a system image of your current setup, which you can then restore in the event your computer had to be returned to Lenovo for repair.

You might want to read through this thread as it has a lot of information relevant to your problem.

I would only delete your Recovery partition as a last resort and when/if you are of the mind to abandon factory bloatware altogether, choosing to Clean Up Factory Bloatware or even eventually follow the course of most tech enthusiasts to Clean Reinstall - Factory OEM Windows 7.

Until then having the Recovery partition is the most stable method of Recovery, for which disks are really only a backup method.

What I would do here unless you're sure you want to get rid of Recovery is to Resize C from the right using free Partition Wizard bootable CD, create a Logical partition there for Win8. PW views Primary Unallocated Space (which will result from resizing) and Logical Free Space as the same for purposes of creating a new partition.

Just be sure to choose a Logical partition to create, give it a label and Win8 will do the drive lettering.

Ideally I don't want to delete anything to do with recovery, but i do want to dual foot win 8. So by using Partition Wizard to create the partition I shouldn't have to touch anything? Leave the OEM partition in place and shrink "C" With PW? When you say "give it a label" do you mean that it should name the partition? Something like "Win8"?

Thanks for your help

Yes.

Burn PW CD ISO to disk using Windows Image Burner or ImgBurn,

Boot PW CD, rightclick C to Resize, drag right border to the left by as much space as you want for Win8, click OK.

Now select Create New partition, NTFS, Logical, type in chosen name, skip letter, click OK. Apply both steps.

Both steps are shown in this video. The only difference is you already have a Logical Recovery partition which is fine since it's contiguous as it must be: http://partitionwizard.com/video-hel...partition.html

Burn the WIn8 ISO to DVD using ImgBurn at 4x speed, boot it to install to Created Partition.

Still not working. Still shows the C drive with 0 unallocated space.
