Ubuntu – Ubuntu 12.10 + Windows 7 – No option to install alongside windows 7

12.10installationwindows 7

I have a 64-bit Windows 7 OS installed at the moment. I have used GPartEd to shrink the current Windows 7 partition on my 720GB HDD to 200GB. I have then made a new NTFS partition of 200GB which I will keep for later on as a shared drive between both Windows 7 and Ubuntu.

So in GPartEd I now have 3 partitions which were all automatically there from the Windows 7 installation, I only shrank the 3rd one from the 698GB or so that it was to 200GB and created the 200GB for the shared drive.

I first tried creating another 200GB partition at this stage to install Ubuntu too but when I burnt the DVD and loaded it, Ubuntu gave me no option to install alongside Windows, only the option to erase the entire disk and install Ubuntu on the blank drive…not what I want to do. So I tried installing it through clicking 'Something else', it downloaded all the install files but didn't install. I then had a lot of problems with getting the DVD drive to work and what not but now have this fixed so I can use Windows again.

So now I've used GPartEd to delete the partitions so again I'm now left with the 3 partitions there which Windows 7 automatically installs and a 200GB NTFS partition I will later use as a shared drive.

Booting up from the Ubuntu disc and again there is no option to install alongside Windows 7. How do I get it to do so? All I would like is Windows 7 and Ubuntu on a dual boot, with a 200GB NTFS partition to dump my work onto so that I can access it from both OS's.

Thanks.

MBR partitioning scheme only supports 4 primary partitions, once you have all 4 of them you can't create any more of them.

To overcome this limitation, you need to create an extended partition, which can act as a container for a number of logical partitions.

You can then install Ubuntu into a logical partition.
