Unable to boot from any external drive

I have used Clonezilla on external hard drives for create image backup, 1stly using Gparted i create 2 partition on external hard disk, 1st one for Clonezilla live boot 300mb FAT32 and the rest NTSF partition to store the images. To install Clonezilla i use Tuxboot. And then restart my pc and boot from the Clonezilla partition then make drive image & store it on NTSF partition. I have used this method on other Windows operating system also like  Windows XP, Windows 7/8, Win 8.1, Vista and Windows 10. I purchased WD External hard drive, everything goes fine but drive not boot to Clonezilla. Only message shows is that no operating system was found. I format and re-installed various Clonezilla version but no solution found. i also run WD diagnostic. How to solve this?

 

Solution:

If you are going to boot via Gparted, you have to convert BIOS installation to UEFI.

Steps to convert Windows BIOS installation to UEFI

  • You have to create a system repair disc
  • Choose disk which you want to convert
  • Download GPTGEN. This will allows you to convert MBR disc to GPT.
  • You were unable to boot your system until the completion of this process.
  • When download finished unzip it. And run command prompt and type as below

gptgen.exe -w \\.\physicaldrive0

  • Boot with windows installation
  • Choose preference and language settings and select Repair your system > Trouble shoot > Adv. option > Command Prompt
  • Disk partition is required, create boot partition, type on CMD

diskport

  • Locate Windows from boot disk with typing below

list disk

  • After that select disk (replace correct number)

select disk 0

  • Verify partition

list partitions

  • Delete old system partition

select partition 1
delete partition

  • Create new boot partition

create  partition  EFI  size=100  offset=1
format  quick  fs=fat32  label=” System “
assign  letter=S
create  partition  msr  size=128  offset=103424

  • Exit from the diskpart

exit

  • Create boot partition data, replace c: with the letter of Windows install (c is by default)
  • After all this, restart your computer
