Please reduce the image size/dimension for future images.
4901x1808 is too large, specialy for such few text -> when ican read the text on the image, i cant read anything of the forum.

* Did you overwrite the EFI partition (as in reused AND formated)?
* Did you leave out the existing EFI partiton (not used at all)
* Did you mark cryptdevice:/dev/sda5:CRYPTNAME (where sda1 is your crypted partition, and CRYPTNAME its dev mapper name) (in /etc/default/grub :: GRUB_CMDLINE_LINUX.
* In most cases, simply reinstall Linux (in the hope you have /home as its own partition), which should fix the 'no OS found' screen, and eventually the missing crypt partition as well - if done right in the installer - depends on your distro.
* In case you built your own kernel, did you enable the dm+encryption modules and did you rebuild initcpio before rebooting?

Hth to get started.

       --grub-mkimage=FILE
	      use FILE as grub-mkimage

       --grub-mkrelpath=FILE
