It appears to me that the bootloader on the nvme cannot find the Elive installation on your other (sata) disk.
If you opted for an automatic report and entered your email address .... and remember the installation date, then @Thanatermesis might be able to see more and tell what exactly went wrong.
BTW does the Elive boot option show up in your BIOS boot options (F12 usually) or do you get a Grub2 boot interface?
