I am using Windows 8.1 Pro installed on a 128 GB SSD, partition-table is GPT. My Asus Mainboard uses UEFI and i installed windows 8.1 as a uefi installation. Therefore the first boot device is selected as "Windows Boot Manager", it's perfectly working and it's really fast. Now i bought a new bigger SSD. I plugged it in and booted with clonezilla to clone the whole disk (disk2disk mode) to the new SSD. I cloned it, turned the pc off and disconnected the old ssd. Turned it on and it didn't start windows, after the EFI-initialization it stayed black. Now i booted with a windows 8.1 stick(only my new cloned ssd is plugged in) and selected the "computer repair options" and navigated to trouble shooting and used the automatic repair. I waited about ~a hour and assumed that it crashed (allthough the circle was still moving). I restarted and tried it again now i am getting instantly the error message that automatic repair couldnt fix my problem.
The only option is to run the terminal and try to fix it.
What can i do in order to use my new SSD with my old windows installation. A complete new installation is no option at the moment.Thank you very much.
