I want to dual boot Windows XP and Hardy Heron. I have partitioned my single hard drive, created a boot-able pen drive with the Ubuntu 8.04.4 LTS ISO, I am aware how to boot and start the installation but the newly made partition is not displayed when it reaches that stage. Someone please instruct me how to proceed.
As the commenters have noted, Hardy Heron 8.04 LTS is no longer supported for desktop use and will soon not be supported, period. Your problem sounds like its a newer hardware incompatibility with the very old Hardy.
Please consider using the latest Precise 12.04 LTS, or if you need a legacy release for some reason, try 10.04 LTS.
