    Upgrading from Windows 7 to 10 - UEFI or Legacy?


    So im upgrading someones laptop from Windows 7 SP1 to Windows 10 and have created a backup image of the computer just in case with macrium. This is a pretty old dell E5250 laptop. As far as i know the 250gb SSD is on MBR and uses legacy BIOS. I plan on just doing the upgrade not a clean install. If i do it via boot menu can i choose either option or do i have to choose legacy? If i do it through just the media creation tool and click upgrade this PC what option would it use by default since i don't think it tells you?

    Hi, if the BIOS is a legacy BIOS only, that's your only option.
    You mention the media creation tool- that's fine- has Win 10 not been offered via Windows Update?

    You may wish to verify other users' experience of Win 10 with it as there is no guarantee of either Win 10 working free of problems on old unsupported PCs or - in any event- of a problem-free upgrade process.
    Possible example of one with Win 10:
    https://www.amazon.com/Dell-Latitude.../dp/B07KSK9MS1

    Upgrade to Windows 10

    This is also possible:
    Clean Install Windows 10 Directly without having to Upgrade First

    Great you're using disk imaging.


    You might like to try running Kyhi's Win10 boot disk on it first and see how that runs.

    Well im pretty sure this BIOS has both has it has secure boot as an option but only if you disable legacy mode. This is what the BIOS looks like
    YouTube
    And thats sort of why im asking should i choose the UEFI one if i do the upgrade from the boot menu.
    As for the creation tool he never really updated windows 7 that much so it was never offered.

    Thank you very much for your reply.

    You could do this after having upgraded:
    Convert Windows 10 from Legacy BIOS to UEFI without Data Loss


    Or clean install as UEFI.

    .
    Ok that looks like something i could do. When i do do it would I have to turn UEFI on first before doing that or after ive done it? Looks like after
    I have also decided to probably just upgrade using the creation tool. It will need to download the installation files (im assuming not in ISO form) but where is that stored? Is it deleted after the upgrade is completed or is it stored somewhere and i have to delete it after?

    See from step 4 in 2nd link my post #2

    One option is to download an iso file.

    Just worried about space, i assume once the upgrade is done its going to leave installation files behind which i may want to get rid of to save space.

    You can download the iso to an external disk.

    Note you need at least 35Gb, say, free on C: to upgrade.
    A lower risk approach is NOT to accept updates when you receive that prompt.

    Other standard recommendations:
    - uninstall any security software
    - disconnect any unnecessary peripherals
    - have only the system disk in the PC
    ....

    Got more than that space so its fine there, was just wondering if it was possible to get rid of that data once done. Anyway it looks like its gone through ok. windows notified me that 2 things were removed during the update. Intel(R) Widi (which is the whireless display thing apparently) but wireless still seems to work ok. And the Intel(R) USB 3.0 Extensible host controller driver. I dunno why that was removed though.

    Glad the upgrade worked.

    If the PC is working ok- and all drivers /devices ok, your priority should be to create a new base (initial) disk image.
