Right, let's go!
Don't worry about your KEY if you are going to restore your backed up activation data after, Win 7 will allow you to install without a key, just proceed without one when asked.
Download the official Micros0ft Windows 7 Home Premium 64bit with SP1 ISO file
HERE:
Download the latest version of ImgBurn
HERE:
Install and use ImgBurn to burn a Windows DVD so you can use it to install Windows on your PC.
Insert a blank DVD disc into your burner.
Run the ImgBurn and choose the first option, "
Write image file to disc". Click on the source yellow folder icon and point it to your Windows 7 image file (you just downloaded).
Click on the "
Destination" drop down and point it to your blank DVD disc drive (It may already be selected).
Click on the Write Icon (picture of two discs with arrow in between) which should be highlighted now to start the burn process.
Once you have your new shinny Windows DVD,
Your machine BIOS needs to be set to boot from DVD\CD as first device & may be already set that way? or, you may have a boot F key on startup to choose which drive to start from (Depending on machine type)?
Either-way, once you are ready to say goodbye to everything remaining on your HDD lol It's time to reboot your system with the Windows DVD in the drive and follow the prompts to install Windows.
At some point it will ask you which drive you want to install to and offer to format it. I would format it to NTFS and let the process begin.
Look in "Computer" to see which drive(s) are installed on you system if more than one. Familiarize yourself with the drive size and free space so as you can easily identify the one you wish to install too later ;)
You could if you were anyway unsure, physically detach the drive data cable from all the drives except the OS drive before you start, that way you will only see one drive so no confusion lol
Have a read over this before you begin & holler if there's anything you require further clarification on.
Keep access to another PC so as you can come back here if you need any other advice during the process ;)
PS, as with all delicate procedures, there is always an element of risk :( so if we don't see you on the other side Linny, It was a pleasure knowing you virtually lol I'm only joking LOL
Off you go & the best of luck
