Dual Boot XP and Win7 - Experience request

[Robbo88]

I currently use a Win XP (3) system on my machine and I am having extreme trouble with using CoD. After reading a few posts it appears XP is rather a dud if you want to have CoD even start reliably. My system is not great, Intel Core 2 Duo 2.4Mz (O/C to 3.02Mz), 4 G of Ram (DDII) and a Radeon HD5770, 1G Ram, but still should load CoD but it only locks up.

Hence the thought of loading Win7 but as I do not want to reinstall years of programs I thought that to use Win7 as a dual boot and reinstall Cod on that system.

Has anyone got any thoughts on this as I would like to get CoD running and am looking to the future when it will be making progress in its functionality.
