    OS no longer being detected


    Im not sure what happened but my Windows 10 is no longer booting at all, I know its still there, but something happened to the files used to boot properly, are there any repairs that can be done using installation medium?

    Hi, first please state exactly what you see on your screen when you try to boot.
    - we don't know if your PC is showing anything on the screen, completing POST or if there's a CMOS battery problem, for example),

    Second, confirm you can boot to your BIOS/UEFI. Is your disk shown there at all?

    Third, check the disk (you can do that by connecting your disk as a USB disk to another PC or by creating a live boot disk on another PC and booting your PC from that and running Crystal Diskinfo.

    If the above are ok, then try booting your PC from a Win 10 install disk, via 'Repair your computer' to Avanced Startup Options and running Startup Repair.

    Make a careful note of what it reports.

    You could also boot your PC from a Macrium Reflect boot disk and use the Fix boot utility - run that and make a note of what it reports. That's more comprehensive than Startup Repair.

    Do you use 3rd party disk imaging? - If all else fails you can restore a recently created disk image.

    If you have another PC, try this.

    Install Macrium Reflect (trial version will work).

    Create Macrium USB Rescue drive.

    Boot from it on your pc, and use "fix windows boot problems".

    With luck, it will fix issue. If it does not you can rescue your data assuming you can see your C drive.
