I've downloaded suse 10.2 beta and to save burning all the discs I thought I'd install using the isos stored on my hard drive, this is how I installed suse the first time I tried it (version 10.0).
Well I've tried it but it keeps telling me there's no media there. I checked on the suse site and it seems I need to download 2 files from the installation repo but since the betas don't have installation repos I tried the 10.1 files but it still said there was no media.
Is there any other way to install it from local isos?

If I understand your question correctly, Yes - mount the ISO as a loopback device. This Anandtech article covers it pretty well (there are 3 topics in the article, mounting the ISO image is the first one)

The short answer is that you just need to
where <ISO filename> is the actual image filename, and <mountpoint> is your mountpoint

Sorry, after re-reading my original post I realise I didn't quite make it clear what I was trying to do.
I'll try again.
I downloaded the isos and saved them on a free partition.
To save on discs I only burned the first one.
I then put this in the drive and booted up to install suse.
At the boot menu there are various option at the bottom to slect a language and resolution etc and there is also an option where you can specify how to install suse, from cdrom, net install, hard drive etc. So this is before suse is even installed.
I chose hard drive and it asks where the images are stored so I specify - /dev/sda6/iso but it complains there are no images there.
I've tried following the instructions on suse website which suggests downloading 2 files and pointing grub to them, which I also did but it still can't find the images.

I eventually got fed up of this and just went ahead and burned them to disc.
Well, I thought that would be the end of the hassle but I was very much mistaken. But that's another story...

OK what you must have done is to put the first CD and "INSTALL MINIMUM SYSTEM" without GUI / X and complete installation. It might be possible (as far as I remember in suse 10.0) you have to put more then 1 CD in even minimum system install. In that case, when the YAST installer asks you for next CD just press SKIP and then complete the minimum installation.

Now boot the machine and then mount all the ISOs and then add them in YAST source. Now select KDE/GNOMe and everything will be installed properly.

Actually, the correct title of that often linked article is "How To Ask Questions The Smart Way"; and it's by Eric S Raymond & Rick Moen.
