Primary Drive (removable drive) problem

I have to install 6 new hard drives on our network. I understand that to format and fdisk the drive I have to set the floppy drive as the Ist boot and hard drive as 2nd and so on. I have managed to successfully format and reimage just one new drive, my problem is that the next 2 that I have tried to do the same with still boot up with a PXE boot even after I have configured the Boot Priority the same as the Ist one. I have disabled the PX boot in the Priority list, I have checked all cables etc. but still no luck on getting the floppy drive to read the disk first. Any help anyone?
