iv got a old dell Dimension 4550 which i would like to install win7 on. i asked for a bios mod some time ago but was unable to extract the bios file from the exe. so it looks like I'm going to have to use a loader of some kind...which I'm not keen on. so I'm wondering which one would be the best to use??. as iv never needed a loader on my other pcs. iv always had the bios modded.
