    bootrec /scanos and /rebuildbcd finds 0 windows installations normal?


    Is it normal for bootrec /scanos and bootrec /rebuildbcd to find 0 windows installations? From what I've gathered by searching online, it's quite not normal, but it also seems to be only for legacy BIOS. I'm using UEFI and can boot into windows fine, but bootrec still only shows 0 windows installations. Just confirming here. Windows version is Windows 10, 2004 (As a side question, UEFI always puts the boot and bcd files in it's own partition while BIOS places it in C:/boot right?)

    :)

  2. bootrec /scanos Returns 0 windows installations.

    Hey,

    I have a dual booted PC running Windows 10 and Ubuntu, from which I removed Ubuntu and grub. I have been able to boot into the Windows successfully but when in recovery i use commands such as bootrec /scanos or bootrec /rebuildbcd it returns, 0 windows installation
    found. How is this happening, and also is it harmful in any way for my pc.

    bootrec /scanos or bootrec /rebuildbcd not working

    I'm getting an odd issue where if I run either command, they don't run all the way through. bootrec /scanos doesn't tell me how many (if any) installations of Windows were found, and bootrec /rebuildbcd tells me it might take a while, but then quits after
    a few seconds with no other words.

    Might be worth nothing that bootrec /fixboot returned as having denied access.

    Any thoughts?

    bootrec /scanos and /rebuildbcd finds 0 windows installations normal?

    bootrec /scanos Returns 0 windows installations.

    the bootrec/scanos command only shows installs which are not already included in the BCD store. If you can boot your system, it must be there. Rebuildbcd should have seen something.

    I don't have a lot of experience with Grub so can't really speculate on whether it might still be active.

    While you are in the command prompt, type bcdedit and see what the listing shows.
