G'Day guys again......Havt got new puter...160gb windows xp 2nd edition loaded
My old puter had 98sp loaded ( Ive stripped it to bare essentials) 40gb
What I want to do is introduce them to each other without loss of data on either drive.............Can I do this and have the option to decide which OP system (or DISK drive) at the start MENU.....( thanks for all your help in the past)..cheersThe best solution in to load the oldest Windows on the first partition of the first physical hard drive. Then load the later version on either a second partition or a second hard drive. That second version will install a boot loader automatically so you can easily choose at boot what operating system to run.

Other solutions are changing this in the BIOS, or physically plugging in ONLY the hard drive you want ACTIVE. These WOULD vcertainly be NOT my first choices.

You may have to reload to get this set up right, but good planning SAVES a LOT of problems later.  Thanks AGAIN Mate I Understand what U said...( Good Planning !!!  )......Then again We ALL WISH we had the gift of Foresight....All Ure help to me in the past  has been MUCH appreciated...Im SURE I'LL have more Qs in the future...... Glad to help. Feel free to post back.
