    Hi, you’d better back up all your important data. And if you would like you can make a new partition for installing a clean new Windows 7 with Partition Wizard.

    You can transfer the memory to a storage box, put windows 7 on and then put the memory back

    Installation of Win 7 on C: won’t delete data on D:. However, will your “old laptop” support Win 7. 32 bit requires min. 1GB RAM while 64 bit needs 2GB and are hardware drivers available. If you’re so worried about D: data, back it up to an external HDD or flash-drive.

    Files on drive D should be fine as long as you don’t install Windows 7 on that drive. Installation only takes place on the drive that you select and will not interfere with any other drives that you may have on your computer.

    I can think of 2 options for you.

    Option 1:

    Purchase a new hard drive and install windows 7 on that.Take your old drive and install it into a USB external hard drive case. This way, your files are safe for you to copy over to your new drive or put anywhere you want. I have done this option a few times.

    Option 2:

    Backup your important files and then use the Installation disk to format the system files partition and install windows 7. This step is a little more risky if you haven’t installed Windows before.

    If C drive is where your system files are, then formatting that drive will only delete the system files, program files, and regular files that are there. Any other drive, or partitions should not be deleted unless you go in there and tell it to wipe it out. Also, you will have to re-install all of your programs that are installed to the second partition.

    If you need more instruction on how do the install, I can give you some basic instruction here.

    If you are installing on the C: drive, even with its formatting, files stored on the disk D: isn’t threatened.

    Igor Rizvi,

    First and foremost, before proceeding for clean installation of Windows 7, I would strongly recommend you to take a backup of your important data and other files you require.

    Secondly, please contact the service engineer of the company whose laptop you are using. They will perform the necessary action and thereby ensure safety of your data.

    Better to take full precaution rather than regret over loss of data.

    Regards.
