I have installed Windows 7 on my laptop and then wanted to go and install Ubuntu 12.04 afterwards. When I installed Windows 7 I created a couple of spare partitions. I then used the Ubuntu USB boot method (and later on I downloaded the normal 12.04 desktop 64 bit Ubuntu). Whenever I insert the Ubuntu CD in and then select to install Ubuntu it never recognised the 64 bit Windows 7 installation.
I have managed to do this in the past (and I swear I had Windows 7 first and then Ubuntu second).
Could someone please advise/help? I have now used three different Windows 7 installation disks and 2 Ubuntu (USB stick 12.04 twice).
