System not booting into Manjaro after cloning, but boots into Ubuntu

Hello forum, I’m sorry if I’m not providing all the information, I’m new to this.

To provide some context: I have a dual boot system with Ubuntu and Manjaro on a 240gb SSD. I cloned the old SSD on a new 500gb one using Clonezilla and now when I try to boot I’m only able to boot into Ubuntu, the Manajro installation is not recognized anywhere, not showing in bios, not in the boot menu. The partition is still there and the data is intact and accesible.

What can I do about this? Rebuild the grub? Repair the partition table? I’m a noob, sorry. Right now i’m creating a manjaro live usb from ubuntu.
