I am running two hard drives, an 80GB IDE & 500GB SATA on an ASUS P5LD2 SE motherboard. WinXP Home was originally loaded on the IDE HD set as master. I upgraded by adding the SATA HD and did a fresh installation of XP Home onto the SATA with the intention of copying all the relevant data files from the old system onto the new. This all worked successfully, and gave me a dual boot option on boot-up. I then formatted the old IDE HD with the intention of using it as a storage depot. However, my new installation on the SATA HD would then not boot. I used a floppy disk NTLD Boot Loader program to boot back into the new system on the SATA HD and tried to modify the boot.ini file, but ended up wrecking it, and couldn't boot into the new system even with the floppy. As a work-around I reloaded a bare-bones copy of XP Home on the first IDE HD and this restored the boot file so I again had two boot options on boot-up. I then modified the boot.ini to only show the new boot option on boot-up. My question is: Can I create a boot.ini on the SATA operating system so it will boot independently of the IDE HD as I want to format the IDE HD?
