Since Win 7 was installed first, if you delete it you will loose your MBR and that is bad. You will not be able to boot your PC.

You are better off creating a complete Image of Win 7 then. . .

Reinstall Win 8. During the initial phase of the installation, delete all partitions and format the entire HD, then Custom Install Win 8.

Hi,
Thanks for your reply. I believe when i did back up my C: drive, it created image file automatically.

Also, can i reuse the window 8 key if i want to reinstall it on my same laptop?

Be careful when you say it backed it up automatically. Did you use the Windows 7 Backup and Restore app. If so you may not be able to access the Image. Did you create a System Rescue Disk. I would definitely choose a good 3rd party Imaging app, create a Rescue Boot Disk with that app and create an Image using that app. Then not only will Win 7 be backed up, but the MBR will be backed up as well.

Which Win 8 key are you talking about? As long as you have a legally acquired key, you can install it on the same PC as often as you wish to.

sudarmani, welcome to the Forum!

If you want the $40 upgrade to Windows 8 Pro next week, leave Windows 7 installed. When you make the purchase, to qualify for this pricing, Windows 7, Vista or XP MUST be installed/activated/validated. Otherwise, you'll have to reinstall & activate Windows 7. It wouldn't be necessary to update the OS though, if you don't plan to keep it & go with Windows 8.

Just wanted to make sure that you knew this.

I would try Macrium Reflect as a possible free Imaging tool. I do not use this as I have gone with Acronis TIH 2013, but this app is not free.

You do not have to try to format your HD and create a fresh partition ahead of time. This can be done when you start the installation procedure. One of the early screens will give you the option to format any or all partitions on your PC. Once you have formatted the partition, Win 8 will create the partition for you.

Hi Medico,

Ok cant i format all my drives, do a fresh partion and reinstall my win 8 again? wont that solve my problem? Yes you can, but why all of the work? Just leave things as is, assuming that Windows 7 is installed. Like Medico has suggested, Macrium Reflect Free is a great disk imaging app, I used it for 2 to 3 years. Backup your entire hard drive & make sure to create a Bootable CD to recover with, prior to 10/26, or whenever you plan to install 8 Pro. All who plans to install Win 8 should backup whatever OS is installed, plus their Data.

Download Macrium Reflect 5.0.5167 - FileHippo.com (http://www.filehippo.com/download_macrium_reflect/)

On 10/26 (next Friday) go to the approved site, it will be posted on the Forum. Go through the purchase procedure, making sure to download the ISO (if too slow a connection, a DVD will be shipped for a small extra fee).

Once you make the purchase & download the ISO (avoid the small Upgrade file), then make a Bootable DVD from it. From there, is when you want (& are required to wait for) to format your HDD & install Windows 8 Pro + Media Center. If you formatted the drive containing Windows 7 & 8 RP now, you'd have to reinstall/update 7 again to obtain 8.

As it stands now, unless there's something untold, there is no problem. You've got 9 days left, backup what you have to be prepared. That's all that you can do at this time. You may wish to boot into Windows 7 to make sure that OS is intact & OK, & update it while you're there.
