Over the christmas hols I intend to upgrade my motherboard/cpu/graphics card/ram, retaining my present hard disks, one IDE,one Sata. Both these disks have XP pro installed, I select which to boot from with option in BIOS. The problem is, the new motherboard has only one IDE cotroller, so I will have to set up the CD/DVD drive as slave with old hard disk as master on the one controller. I am wondering if I will be able to boot from the CD drive (set as slave) should I need to reinstall windows after the upgrade? My current system has two IDE controllers, one with hard disk, second with CD/DVD drive, so this problem does not arise.
OK - thanks for reassurance FE. Wasn't sure as I have seen some references which seem to suggest that optical drives must be set as master on IDE controllers in order to boot from them. In answer to your query about dual booting - in the (hopefully) unlikely event of a disastrous system failure, I can be back up and running again simply by booting from other HD.
