Perform a Custom Install to Upgrade from Windows XP to Windows 7

TIP1: If you are running Window 5 (XP) even with SP3 you will most certainly require a Custom Install, this is a 5 step complex process so don't rush it, to upgrade to Windows 7 if you just go ahead and expect that the upgrade CD will do everything for you dissapointment will most certainly be your results.

You will need at least 1GB of RAM ( or 2GB if you want to use the Windows (x86) 32-bit XP compatibilty mode on Windows 7 if your hardware won't support hardware assisted virtualization technology then this mode is not for you so 1GB will be fine) and a 1GHz processor and 16GB of free hard drive space if you don't have these forget it. Also you will require a graphics card that supports Aero for full use of all Windows 7 functionality so you might want to consider a new AGP graphics card as well your choice.

There will be several driver issues with webcams and other devices that will not work after the upgrade run the Windows 7 upgrade advisor tool before you even attempt it, you will also require the Windows Easy Transfer Tool later on so download this now.

I suggest that you first create a drive image using Ghost v14.0 and save a good image of your old WinXPSP3 partition prior to the upgrade. This will be your safety net restore points can't help you here. Its also worth using the preboot antivirus scanner bundled with Ghost before the upgrade you can use my autoupdater Antivirus Defintions CD creator to ensure you can scan with the latest defntions, download this from either LINK1 or rapidshare LINK2 these are posted exclusively for Fixya users.

Follow these instructions HERE in this PDF to assist you you will require an external USB and the I386 cabinet files from your OEM preinstalled version or from the original WinXP CD and the Windows 7 upgrade CD.

Also your WinXP must include the NET. Framework v2.0 x86 (32bit) runtime files and at least SP2 prior to the upgrade, I suggest you check using these NET Framework check tools to see what version you have. to check your service pack type c:winver at the run prompt

TIP2: If you have DRM (digital rights management) protected files from iTunes or similar download sites check that these can be restored after the upgrade if not back these up first as a matter of course.

TIP3: The upgrade from Windows Vista (v6.0) is a bit easier so if in any doubt upgrade to Vista first then Windows 7, if you miss out a step you can render your PC useless hence the first image step is highly recommended if the upgrade fails.


Good Luck !
