    How to add more than default windows 10 boot by creating boot option?


    How to add more than default Windows 10 boot by creating a boot option on the OS startup ?
    The OS booting in a partition lettered C as usual



    Now a partition, lettered E:, is readily prepared to launch the windows 10 installation in typical size around 3.3 GB after the extract of the iso file in installation CD


    It'd be nice for a user to just restart windows, choose and run the installation if malware has destroyed his current running system.
    Now, how is it to make it work, as Windows multi boot option on startup here is the only method for launching it ?

    if malware has destroyed his current running system.


    Take a different approach which keeps everything away from the infected disk: use disk imaging routinely to secure your OS (and any other partitions or disks as we keep recommending).

    E.g. Macrium Reflect (free) + external storage for disk image sets.

    If your disk fails or is unbootable or attacked by ransomware- restore your disk image. Gives you a second chance when something bad happens without needing technical help.

    Take suggestion from @dalchina, use Macrium. However, to answer your question. Here's how it works:
    Copy and paste the code and save it to a file on desktop, ex. mkdual.bat then right click to run as Admin
    NOTE: in the code, assuming you have Windows Installation in the root of E: drive.
    use only one line in red, use winload.efi if your Windows installed with GPT disk
    else use winload.exe for MBR disk.

    Code:
    echo off
    echo Configuring Dual boot Windows 10 Installation
    bcdedit.exe /CREATE {ramdiskoptions} /d "Ramdisk Options"
    bcdedit.exe /SET {ramdiskoptions} ramdisksdidevice partition=E:
    bcdedit /set {ramdiskoptions} ramdisksdipath \boot\boot.sdi
    for /f "tokens=2 delims={}" %%g in ('bcdedit.exe /create /d "windows 10 Installation" /application osloader') do (set guid={%%g})
    echo GUID = %guid% created !!!
    bcdedit /set %guid% device ramdisk=[E:]\sources\boot.wim,{ramdiskoptions}
    bcdedit /set %guid% osdevice ramdisk=[E:]\sources\boot.wim,{ramdiskoptions}
    bcdedit.exe /SET %guid% systemroot \windows
    REM ========== Use this line below if your Windows installed using GPT ==========
    bcdedit /set %guid% path \Windows\system32\winload.efi
    REM ========== Use this line below if your Windows installed using MBR ==========
    bcdedit /set %guid% path \Windows\system32\winload.exe
    bcdedit.exe /SET %guid% winpe yes
    bcdedit.exe /SET %guid% detecthal yes
    bcdedit.exe /SET %guid% nx OptIn
    bcdedit /displayorder %guid% /addlast
    bcdedit /timeout 5
    echo "Done... Reboot your PC"
    pause
    Reboot. You should have a menu with Windows 10 & Windows 10 Installtion.

    @topgundcp
    Can you repeat giving the code again, please... your code is not clear, don't have the newline

    Also I really don't understand :
    NOTE: in the code, assuming you have Windows Installation in the root of E: drive.
    use only one line in red

    I said:
    Now, a partition lettered E:, is readily...

    Will it work for "the first start of partition E:" instead of "
    the root of E: drive. " ?

    and I simply didn't get :
    use only one line in red


    Please help me do me a favor, I am really grateful for your benevolence..

    Norton Ghost is another great choice. But not free.

    Norton Ghost - Download
    No way!!!

    Norton Ghost has not been supported for many years and does not even support UEFI installations which is vast majority of Windows 10 installations these days.

    Use Macrium Reflect Free which is far superior (we have tutorials in tutorial section) and as name implies it is FREE!

    I haven`t used it since school, my bad, post removed.

    I should have suggested Macrium too, Macrium rocks.
