ok so the first thing you want to do is to remove all storage drives, then hook up one ssd & see if it gets detected by the bios - and if it does, does it have a bootable partition on it? if not, remove it & switch to the other one & do the same thing.
if neither is bootable, it may be that the bios is confused - reset it to factory defaults & try again. if it still does not boot then use your recovery disk to boot to a shell to determine which ssd has media that you're going to have to lose, use fdisk to create a bootable partition, then reinstall the OS.
if your recovery/boot disk doesnt work at all, buy a new usb disk & get someone else to create a boot disk from their computer.
