    Help on a clean install project...

    Hi all,

    I am interested to do a clean install of Windows 8.1 on my desktop. However, I am not too sure about the exact steps when it comes to HDD format/delete processes. I have checked I have 3 partitions labelled as volume 0, 1 and 2. Then there was a system reserve volume of about 350 MB. In hindsight I should have taken a photo of the screen then and post it here! Anyway, I have a workable USB iso file...

    I have a few questions :-
    1. Which partition do I delete first - volume 0, 1 or 2 - or delete the system reserve volume first.
    2. What happens after that? Do I do a format or what?
    3. When can I safely take out the usb stick from the desktop?
    4. Would a computer restart in the midst of doing the clean install, and with the usb stick still in the computer, has any adverse effect to the installation process?

    I hope you would be able to comprehend my post....cheers!

    If you are installing 8.1 from usb or dvd, you can remove all the partitions and leave just the unallocated drive space and then allow the windows setup to create the needed partitions.. just follow the prompts, nothing special to do..

    but then you have to install all your system drivers - you really need to get these from your system's mfg's website first and save them to a disk or usb..

    there is a tutorials section in the forum - with some good how to's

    Ok...I got a screenshot of my harddisk listed below. I have a C and D drives - D drive is my data drive which I like to keep. I would like to clean install Windows 8 or 8.1 on C drive. Guide me on this....

    On diskmanagement tool you get the image below. When doing Windows installation I get a different image - that's my concern...(sorry I don't have a screenshot of it). That's why I me on this...!

    How do I go about highlighting to delete which partition first and so there a fixed sequence? Some screenshots would be nice...thank you.

    The last, OEM Partition is most probably backup partition for OS from Lenovo. Did you get or make backup disk to restore to factory condition ? Or, are you going to install windows anew from a disk or USB ?

    No I didn't make system backups. I already have my personal files in my cloud account. I was trying to get rid of Lenovo's bloatware! My desktop was originally a Windows 7 Home Premium edition. Subsequently Windows 8 and later 8.1 was launched, I upgraded it.

    I suspected the initial Win 7 Lenovo drivers and bloatware were incompatible with my Windows 8.1 64-bit edition. I experienced vertical blue lines on my monitor. That's when I did a reset with a usb ISO installation media - something akin to a factory reset in Android. It went well. I don't experienced any vertical blue lines anymore.

    I was just curious to do another (clean) install with no residual Lenovo stuff on my desktop - including the backup partition - since Windows 8.1 has all the necessary drivers, as attested by the removed apps list Windows generated after the reinstallation. All Lenovo stuff were not reinstalled...

    Thank you KYHI, Maverick and CountMike for your inputs...

    In that case you don't nee OEM partition. You can either make it as a new one or extend D: partition with that space. During installation you can choose to install Windows as new installation on C: partition and let windows format it. Nothing should happen to Other partitions during that time. I like giving drives and partitions unique names as their letters can change depending on installation or other OS used so with their unique names I always know which one is which without confusion. I would also look up for 8.1 drivers at Lenovo, they might be better and newer than MS supplied drivers.
    This: Free Partition Magic alternative and Partition Manager Freeware for Windows XP/Vista/7/8. is my preferred program for work with partitions but for work with OEM partition you may have to reinstall windows first as it my be locked by Lenovo software.

    here is the problem with your system - windows 8 uses another 350MB partition that windows 7 does not.. It is the recovery tools partition.. When you upgraded to windows 8 - guess where windows 8 put that partitions? On that OEM partition that's where..
    because it has a volume id = 27

    With a fresh install of windows 8 the 100MB partition will need to become a 350MB partition so windows can use it instead of the last oem partition...

    You are going to need to do a complete "D" partition backup to save your information.. If you to keep the data..

    since you are running 8 now - I want you to create an "Image" folder on your "C" drive and then run this command from the command prompt (admin) - Right click start - select command prompt (admin) copy and paste this command

    Dism /Capture-Image /CaptureDir:D:\ /ImageFile:C:\Image\Data.wim /Name:"Drive D" /CheckIntegrity

    depending on how big that image is you will need to copy that image folder to a removable drive.. that command will create a windows image of your D drive..

    If you want to keep the "D" partition and not the data on it, you do not need to run that command, I just need to know..

    I will stop here for now.. Let me know the image size after you create it..
