I have a PC with 2 drives: C & D (master & slave )on Win XP Pro. I previously had a multiboot system with Win XP Pro on each drive. Worked well. My system became unstable due to hardware difficulties (now resolved). I re-installed Win XP on C drive, but now cannot multiboot. My Win on D Drive is still intact. My Boot.ini is: [boot loader] timeout=30 default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect /NoExecute=OptIn How do I modify to be able to multiboot again? And if I change on C Drive, must I also change on D drive when I eventually solve the problem. I'm desperate, please help!!
