I have cloned a 500GB SSD for my dual boot Windows and Ubuntu system. I can boot into Windows 10 OK but Ubuntu (latest version - 22,04) just shows the Grub menu.
What do I do to get Ubuntu running? Does Grub need fixing?
On my old HDD I added Linux to the original Windows system and it works OK
Thanks to sudodus who suggested Clonezilla. I have used it and now my Linux boots first time.
The Clonezilla live disk is not the easiest to use but it is much better than the Acronis software supplied with the SSD and seems to know Linux well by installing GRUB and initrd files. So I would suggested it to anyone who wants to clone a dual boot system Windows & Ubuntu system.
