My humble opinion is that it is dangerous for average Joe user to delete the System Reserved Partition their computer is booting from - at least without a major warning that deleting the partition will result in a failure to boot until either the conversion utility successfully creates an EFI System Partition or if it it fails another partition is made bootable.
    1) user should make an image backup or backup valuable data as a minimum.

    2) you should always run validate option first.

    Agreed.

    The conversion process will include validating before it actually converts though.

    I finally managed to do the conversion. Here is a summary:

    MBR disk: 4 partitions. SRP with WinRE, OS, extended with two logical data partitions.

    First try failed. Error: two partitions not recognized. The procedure found 6 partitions (not 4). The problem was related to the extended partition.

    I converted the 2 logicals to primaries. Now 4 primary partitions in the disk.

    Second try, also failed. Error: Too many MBR partitions.

    I deleted the last data partitions (a small one, easy to recover). Now 3 primary partitions in the disk.

    After this, the disk layout validated OK, the conversion was a success.

    GPT disk: Recovery, EFI, OS, data partition.

    The WinRe is enabled.

    Unrecognized partition error


    Hi. I can't even validate using the mbr2gpt tool. I am getting an "Unrecognized partition found" error.

    The process does not work with logical partitions. You can convert the logical to primary with MiniTool Partition Wizard Free.

    Or, you can delete the logical and restore it from a backup after the conversion.

    Create A New Recovery Partition


    Note: here we take Windows 8 for example.
    Step 1: Download your Windows ISO directly from Microsoft, which will require your product key to install. (Note: In many cases, this is included with your Windows computer.)
    Step 2: Use Microsoft’s tool to create installation media for Windows.
    Step 3: Look for the Sources folder, where you’ll find install.esd. This is the recovery partition, basically, but in its current state it is useless. To make it work for you, you have to first move it from the ISO or DVD to a location on your hard disk. Next, you need to convert it from install.esd to install.wim via some converters like WimConverter tool, and then copy the install.wim file to a new folder on your C:\ drive, labeled C:\Win81-Recovery. The next stage is to register the file so that Windows knows it is there and can create a recovery drive.
    Step 4: Right-click the Windows Start screen button and select Command Prompt (Admin) on the desktop. Next, in the command line, enter:
    REAGENTC /SetOSImage /Path C:\Win81-Recovery\INSTALL.WIM /Index 1
    Tip: This will register the INSTALL.WIM file as your PC’s recovery image.



    Step 5: Type: REAGENTC /Info.
    Step 6: Type: exit.

    source:
    https://www.partitionwizard.com/part...partition.html

    Try this method but no success. And also usb media already contains install.wim file of about 3.5 gb.

    Hello @gurgurdeep,

    I don't see anything missing in your screenshot. It looks like it has successfully converted to UEFI.

    You will need to boot to your UEFI firmware settings, and switch the firmware to boot to UEFI mode instead of Legacy BIOS (CSM) to finish.
