Old drive in new build?

[TheMaristBoy]

Hello, tomorrow I'll be building my first PC!
But i'll still be using my old HDD because I cannot afford a new one, let alone an SSD.
My current build which contains my files is this:
-Core 2 Duo E7500
-2 gb RAM
-Asus P5KPL-AM SE
-GTS 250
-Samsung 320gb hardrive
-Windows 7 Professional 64-bit dual boot with Windows XP 32-bit

And I'll be putting that HDD in this:
-i7 2600k
-Gigabyte Z68X-UD3H
-8 gb RAM
-GTS 250 (yeah same old... for now)

Is it possible to move it there WITHOUT formatting it? Like maybe a simple Windows 7 repair?
Btw, it's partitioned in half.

You might be able to get away with a system repair with win 7, but XP most likely won't handle it. You can try it, but when changing motherboards, a clean install is highly recommended.

I'd at least try to backup your data files before proceeding.

Back up data..... to my laptop over a router at a whopping 2mbps xD lol looks like I have a long night -___- thanks it gave me hope anyways

If you have a router, both laptop and computer should be running off it. If your laptop is running wireless at 2mbps, I'd run a hard wire to it, at least during backing up. You'll get much better speeds. Hard wired ethernet is 10/100/1000Mbps depending on your router, but even 10mbps is better than 2.

make a partition and back up your data, you will most likely have to format because of the drivers. when the windows will try to boot from the old drive it will use old drivers for your old motherboard while running on the new hardware possibly giving you errors and not even booting up to the windows desktop
