Hi everyone !
I try to install Ubuntu on an old PC with a brand new SSD (Crucial BX500 240GO). I had some hardware trouble : it seems that I can't install any OS through the old computer (neither Windows, Ubuntu or Xubuntu).
So I've tried to install Ubuntu from a newer laptop (host). It works fine but when I plug the SSD on the old PC (target), it doesn't boot.
I've searched a lot and it seems that the problem comes from the compatibility between hardwares : the host is in UEFI mode and the target is in Legacy mode only (old computer).

I tried some tutorials for installing Ubuntu in Legacy mode, such as :
- Before installing, select "Do something else"
- Deleting all partitons
- Creating ext4 /boot 500Mo partition
- Creating swap 4096Mo partition
- Creating ext4 root "/" partition with the rest

It didn't work, I have some trouble during the boot period. I tried a Repair-Boot and then I had

Missing operating system
Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key
Here are the boot-info
- Before repair-boot :
- After repair-boot :

Does anyone can help me to find what's wrong ?
Thanks a lot !
