I want to setup a pxe boot server for installing linux 11.04 amd64 server edition on some blade servers. I had installed 10.04 last year and it worked nicely. I am following same procedure for 11.04 but it is looking for an installation disk in CD-ROM at 3rd step (after keyboard and language options). I tried exporting linux iso cd using nfs mount but on the client side it is unable to mount and when i try to mount it by using shell (available while installation) it shows network unreachable or no network connectivity. If it is not connected to network then how can it pick up linux kernel image and initrd.gz file from tftp server.
I am almost totally confused. Even a little clarification will be very helpful.
