Dual Booting windows 7 as my primary os with vista as my secondary

I currently have a standard computer setup with a windows 7 operating system installed. What I want to do is dual boot with W7 as my primary os but using an esata cable connect the hard drive from my laptop to the computer and have this as a secondary boot option. The laptop hard drive has a full install of vista on it.

Is this possible, every time I think about doing it I worry about the drivers on the laptop hdd and how those will react to my main computers hardware as obviously the laptop hardrive is setup to look at the laptop hardware.

As long as it's not connected via USB you should be able to boot the laptop providing you first SysPrep to move HD to another computer. All new drivers will install at boot.

It's rare Win7 will start up on new hardware otherwse due to conflicts between drivers, SID and HID.

Another method is booting Paragon Adaptive Restore CD on the new hardware to adapt the install on moved HD.

Set the preferred OS HD to boot first in BIOS setup, then boot the other using the one-time BIOS Boot Menu key.

Thanks for the quick response.

The laptop hard drive I want to use has vista installed not windows 7, so in order for this to work do I need to run the sysrep on the laptop hard drive? Am I right in thinking though if I did this then all of my laptop's drivers would be reset.

If I run sysrep on my laptop hard drive then plug it into my computer (using an e sata) which has windows 7 installed this should dual boot fine?

Thanks again for your responses.
