Change motherboards without reinstalling Windows 7!

Don't even need to go through all those steps. Once you got into safe mode,windows 7 will rebuild it's drivers automatically. Boot normally and then install chipset drivers if not already in.

Edit:
One thing though, it gets hectic with RAID and you will NEED to reinstall/rebuild the array. Only circumstance where you will find driver conflicts.

Edit2:

See edit 1 peet.

 

Windows 7 not genuine problem

It seems like that's an OEM windows copy, it will do that the every time you reinstall the OS. If you have the key, next time you see the "not genuine windows copy" click it and choose to activate by phone, everything else is pretty straight forward as it explains step-by-step. If it doesn't work, then its highly likely that you got a Pirate copy.

 

Error in reinstalling the Windows 7

Hi,
A reinstall guide is the replacement of an already present operating system. So if you wish to format your hard drive and put Windows 7 onto this drive then the reinstall guide is for you. Same as a clean install but with the removal all traces of the previous operating system. You can use this guide also for replacing an older Windows with new. Lets say you have XP , and now wish to replace this with Windows 7 using the same hard drive, then these guides are for you.I have problem with the c and d drives.
Can you help me?
Thanks for sharing this information.
