Fix error external driver unable to boot
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?
