Please reduce the image size/dimension for future images.

* 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.

NAME
installboot - install bootblocks in a disk partition SYNOPSIS
installboot bootblk raw-disk-device The boot(1M) program, ufsboot, is loaded from disk by the bootblock program which resides in the boot area of a disk partition. The ufs boot objects are platform-dependent, and reside in the /usr/platform/platform-name/lib/fs/ufs directory. The platform name can be found using the -i option of uname(1). The installboot utility is a SPARC only program. It is not supported on the architecture. users should use installgrub(1M) instead. bootblk The name of the bootblock code. raw-disk-device The name of the disk device onto which the bootblock code is to be installed; it must be a character device which is read- able and writable. Naming conventions for a SCSI or IPI drive are c?t?d?s? and c?d?s? for an IDE drive. Example 1: Installing UFS Boot Block To install a ufs boot block on slice 0 of target 0 on controller 1 of the platform where the command is being run, use: example# installboot /usr/platform/`uname -i`/lib/fs/ufs/bootblk /dev/rdsk/c1t0d0s0 /usr/platform/platform-name/lib/fs/ufs directory where ufs boot objects reside. /platform/platform-name/ufsboot second level program to boot from a disk or CD See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ od(1), uname(1), boot(1M), init(1M), kadb(1M), kernel(1M), monitor(1M), reboot(1M), rpc.bootparamd(1M), init.d(4), attributes(5) WARNINGS
The installboot utility fails if the bootblk or openfirmware files do not exist or if the raw disk device is not a character device. 11 Apr 2005 installboot(1M)
