    Grayed out Windows partition in Macrium Reflect

    Hi there everyone,

    I have installed Windows as well as SteamOS on my Steam Deck and would like to backup my Windows with Macrium Reflect. But it only shows me all the SteamOS relevant partitions (all 8 of them) selectable, the Windows partition is gray and not labeled (the 100MB and 16MB default partitions on top of the regular C: drive partition are not even separately visible). Macrium Reflect Free is running inside Windows.

    Or should I use other software? Macrium Reflect Free works perfectly on my PC (Windows only, no additional OS like SteamOS) by the way.

    Welcome to tenforums.

    Here's how to take a screenshot and upload it to this forum:
    Once you have an image file (e.g. png, jpg) do this:

    If booted into Windows you can create a screenshot using e.g. Windows Snip & Sketch. For more:

    How to Upload and Post Screenshots and Files at Ten Forums

    - from the huge searchable Tutorials section - do have a look.

    Random example:

    I can’t edit the thread anymore. Here are the pics but I don’t think anyone is going to help me out since if they wanted to they would not need the pics and if so see them when clicking on the links posted above.

    Thank you so much for your kind reply.

    Here is your 2nd screenshot which I have uploaded in the normal way for you.

    I have no idea how you are trying to upload your screenshots: if I click on your second picture I see

    Looking at your partitions- I also have no idea what I'm looking at.
    For one thing this is from MAcrium, not from a 3rd party partition manager which provides a whole lot more info.
    For another, this is not a simple Windows installation- a UEFI installation typically has 4 partitions 1 of which is EFI. You have 2 EFI partitions.

    Maybe someone can sort out what seems to be a mess- but you would help yourself by uploading (properly) a 3rd party partition manager screenshot.

    My guess is you'll need to clean install Win 10 or find some way of creating one with the proper partitions.

    Thank you for your reply and posting the screenshot in the right format.

    Every partition visible, including both efi partitions, belong to SteamOS (SteamOS has 8 partitions total and these 8 are the ones that are visible and selectable). The one that’s not selectable is Windows with 3-4 partitions (Windows itself, efi, sys, Recovery; probably).

    Would any other software help with this problem or if Macrium can’t see it, no other software will?

    The way to find out is to try.

    From admin cmd prompt you could try:

    wbadmin start backup -backuptarget:Z -allcritical

    (replace Z with the letter of your backup partition which is presumably on an external disk )

    and see what it offers to do, it will tell you before you confirm as below

    or you could try another 3rd party tool such as Aomei backupper
    Free Backup Software for Windows | AOMEI Backupper Standard

    or even diskgenius free version ( though there is no scheduling with diskgenius, you can do it on demand )
