    Creating rescue media with Macrium Reflect


    I just ran Macrium Reflect to build rescue media on a Windows 10 laptop. In Other Tasks -> Create Rescue Media, I selected Windows Boot Menu, checked Add boot menu, and clicked Build.

    After the operation ended successfully, I looked to see if Macrium had created a new partition on this drive:

    It looks like nothing changed. Shouldn't I see a new partition?

    Meanwhile, on my desktop PC, after building rescue media in the same way, I see this:

    Building rescue media means e.g. you are creating a bootable flash drive to boot to Macrium reflect.
    What did you expect the bootable rescue medium to be created on?

    MR will not create a partition on your internal drive as part of that process.

    The first screenshot looks like MBR, the second, UEFI. Is that what you expect?

    I did two builds.

    The first build was to create a Windows Boot menu. I assume this created a new partition on the system drive (I'm a novice, so I don't really know what to expect). Is it the MBR?

    The second build was to create rescue media on a flash drive.

    No, it doesn't. It uses the existing C: partition. It puts the Macrium boot files in C:\Boot and adds a boot menu item to point to this.

    Thank you! Good article. Now I almost understand.

    Ah, I see the Macrium boot files in C:\Boot. And if I understand the article Dalchina linked to, the boot menu itself is located in the partition called "System Reserved".

    You can see the contents of the boot menu by opening a Command Prompt (Admin) and typing BCDEDIT

    You will see that the 'Macrium Reflect System Recovery' entry loads Macrium's Boot.wim into memory as a ramdisk and boots from this virtual disk. This is how Macrium can restore the C: drive, even though the boot files are on C:.

    identifier {5d990450-dea4-11e8-8460-ecf4bb16b155}
    device ramdisk=[C:]\boot\macrium\WinREFiles\media\sources\boot.wim,{ramdiskoptions}
    path \windows\system32\boot\winload.efi

    osdevice ramdisk=[C:]\boot\macrium\WinREFiles\media\sources\boot.wim,{ramdiskoptions}
    systemroot \Windows

    systemroot \Windows
    detecthal Yes

    To add to this, there is a slight risk that power fails in middle of doing the restore, and you can no longer boot into Macrium. Additionally, if pc drive corrupts or worse fails, then the boot menu entry wil be rendered unusable.

    Thus all users MUST create a usb flash Rescue drive and TEST boot from it.

    The OP knows this as seen in post #3, but the point is well worth making for other readers of this thread.

    True - I was really emphasising need to Test Boot. I had an issue whereby a pc would not boot from an MR Rescue drive and it can down to needing a driver to be included.
