Windows 10: 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 ?

GPT MBR

If the drive is less than 4 TBs in size, then setup will default to MBR. Yes, you can dual boot in MBR.

How to: setup a dual boot configuration with Windows
10 and previous versions of Windows

 

Time computer takes to boot up

For me, Windows 10 boots up faster than Windows 7, which is how this computer left the factory. Not by a huge amount, mind you, but it's noticeable.

If your computer boots slowly, the first thing to do is to see what other programs are starting along with Windows, since they often add to the boot time.

 

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...

@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..

 

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.
