Unable to install Ubuntu 9.04

[greythorne]

Need your input here,

I am trying to install onto a single hard drive which has been partition into 3 parts. first partition is used to install windows7 RC, second is used as a backup and third will be used to install ubuntu-9.04.

But you see the problem is that when i start the installation, only a single partition is being recognised which is the entire hard drive. I do not know why the other partitions i made did not show up!. I am trying to install ubuntu into a seperate partition in the same hard drive because i need windows7 RC for testing as well.

The hard drive is an 160gig SATA-2 drive and i am using the live-CD to do the installation in this way i can atleast test before comitting.

Any help would be greatly appreciated.

Thanks.

I'm having the same problem. I have a C disk with Vista.

I shrinked it 100 gb so I can install linux on that part.

But when I want to install Ubuntu it says I have no operating system on my laptop and it shows the whole harddisk.

Hopefully someone here can help, im trying to transition to linux full-time. Fedora 11 preview also giving the same issue.
