Moving an existing XP install and programs to a new computer

by amajamar / September 22, 2010 8:05 AM PDT

I want to set up a new pc with Win7 and XP Pro in a dual boot setup. What I would love to do is migrate my existing harddrive from my current computer to the new one. I am aware of the changes of OEM XP software, however, if I was to do it could I use a new OEM install key to reauthorize the old (existing) installation? The one I want to move is an OEM as well, and I know that the existing key won't work. Or, do I need a "retail" version XP key? Or, is the best way to proceed to install a new OEM XP installation on the new computer and migrate all my applications?

Any advice along these lines would be highly appreciated!

Thanks in advance!

By design moving an existing installation ...

will not work properly.

The proper method is to get a new copy (OEM or Retail, your choice) and install it on the new computer. Since you want a dual boot you would want to install XP first as otherwise you will need to edit the BCD.

All programs will also need to be freshly installed but data files are easily transferred.

Boot Configuration Data but it's not imperative

In reply to: Good advice

There are other ways to accommodate 2 operating systems and keep them completely independent. When I did this in the past, I installed each OS on separate hard drives with only one drive in the box at a time. I preferred to just change the drive through the BIOS as I tended to use one OS 90+% of the time anyway. My MB BIOS allowed me to hit F8 for a boot menu easily enough and I didn't need to swap the boot order each time I wanted to change it. Another method is outlined here.

It allows a pause to select the boot partition of choice. I never used this method.

Steve, the boot.ini file will not ...
by Edward ODaniel / September 24, 2010 12:42 AM PDT

allow booting to Vista or Windows 7 as the BCD replaces the need for a boot.ini file for those versions - they simply ignore it.

IF, in a properly configured multi-boot config, you select to boot to XP then and only then will the boot.ini be used and only for the options within it such as selecting a boot to yet an older version of windows or a safe mode or a cmdcons mode.

Can you elaborate

on your install of 2 operating systems on one computer a little further? I've posted exactly this scenario in the Win 7 forum seeking answers on how to do it. I'll also be using one OS, Win 7, 90+% of the time, but still have a need to have XP MCE OS. I'd like to do this using a new retail/OEM copy of Windows XP MCE, a new Win 7 Home Premium 64-bit and a new computer to do it all on. Virtual PC and XP Mode in higher versions of Win 7 won't do what I need. These versions are meant for productivity programs and such from XP and that is not my issue. I have other software/hardware that run in XP and are not able to be ran by the Win 7 XP Mode or virtual options.
