    Is installing a clean windows 10 on OEM laptops impossible [discuss.]


    hello
    the thread title was meant to be "Is installing a clean windows 10 on OEM laptops impossible without losing associated manufacture recovery methods [discussion] " but you know i can't use more letters for post title
    first of all i'm not a computer expert but i know some basics so excuse me if i mentioned any unintended wrong info
    i have a Lenovo laptop that came with windows 8 preinstalled , i upgraded to 8.1 then to 10 which i'm using now and it's pretty good
    the feature i liked most in 8 and 8.1 was "Reset PC" which helps a lot when performance declines
    probably this feature is not doing well in 10 or let's say it's broken as it's gets stuck when i tried it and many others said
    i wanted to get a fresh clean install of windows 10 so i downloaded windows 10 ISO file from Microsoft , mounted it to USB then tried to install it
    if i boot using legacy BIOS mode i get into a problem that my hard drive is of GPT format type and i should convert it to MBR in order to install windows
    if i boot using UEFI i cannot boot from USB then i cannot install windows
    well i know that MBR doesn't allow you to partition your HDD into more than 4
    this means if i converted GPT to MBR i can't use OneKeyRecovery because i'll have to have only 4 partitions *not to mention the data loss or having to buy a 3rd party app*

    now i have to options
    1- using windows 10 as it is and in case of decline in performance i use the restore point i created after upgrade
    2- formatting my HDD using MBR and losing OKR to get a fresh install of windows 10
    what is your opinion ?
    is there any method to force windows installation on GPT partition ?
    thanks in advance
    N.B : i don't know if this is the most suitable section to discuss this so feel free to move it

    How did you create the USB for booting?

    Here is a Tutorial and I used option two with Rufus as I had saved the ISO to my system.

    This is definitely possible, but my question to you is why do you want to keep the older recoveries? They are just taking up space once you move to Windows 10. At least for Lenovo there should be a tool to redownload all the pre-install junk with Windows 10 versions so long as you have a recent computer that Lenovo deems worthy of a Windows 10 upgrade.

    Any time you pave over the original OEM operating system you are going to overwrite (or delete) the utility in the root of the system drive that the manufacturer puts there to sense the keypress at startup that starts the recovery process. You need to contact the manufacturer and download the utility in order to restore access to the recovery system put in place at the factory.

    Option two here, http://www.eightforums.com/tutorials...e-windows.html is what I do to create my bootable USB thumb drives. When done this way with diskpart they work for UEFI and legacy BIOS. My laptops have UEFI and my desktop PC's are legacy. My wife's Acer laptop is very fussy as to how the thumb drive is formatted. If I do it any other way it will not boot from it. It has to be formatted in Fat32. My ASUS laptop is just the opposite, it will install in UEFI even if the drive is formatted in NTFS.

    Is installing a clean windows 10 on OEM laptops impossible without losing associated manufacture recovery methods?

    OEM recovery partitions are pretty much pointless in my book. Not much better than restore points. I mean, if your drive suffers catastrophic failure or simply becomes corrupted then the recovery partition will be lost and the user has no way to recover unless they get recovery disks sent to them by the oem.

    The only robust and efficient method for recovery is by having your disk images and file backups stored on a separate disk, plus a bootable rescue disk to access them.

    In my opinion, users should do a clean install and delete their oem recovery partitions. There are so many good backup programs available and many are entirely free. Please ask for suggestions of good backup programs if you want to consider this option

    You need to change your boot order in the bios so that you can boot straight from your usb. Then the Win10 installation media can perform the clean install

    It can also be because of the way the thumb drive was formatted/created. My Wife's Acer laptop will not boot from a thumb drive in UEFI mode unless its formatted in Fat32. It's not even listed as a boot option if it's formatted in NTFS or not made active. I tried many options, like Rufus, with no luck. I finally went old school with diskpart and got it to work.

    Doing a Clean install of Windows 10


    Well I am following this thread and am not very successful in getting a clean install done (properly)..

    I read the instructions on how to do the clean install and followed them as best I could. It all went well.
    I used a USB stick to do the installation. I had to skip the license key. But my existing operation system was Windows 7 Pro and it was activated.

    So I went through the install procedure. I chose the advanced method to install windows 10 which means I formatted my harddrive. I then put windows 10 on the computer and it went well.

    But after it was all over - I see that windows 10 was not activated. I had a clean installation in place, but no longer activated.

    What did I miss?

    If Windows 10 was never installed and activated on that PC before, you have to do the free upgrade first. You have to do the free upgrade and activate on that PC before you can clean install.
