After the last time you showed the Disk utility images of your SSD OCZ Vertex and the PNY USB installer , with the SSD being formatted ,
- Did you reinstall Sierra on the SSD you had named "Sierra Install" on the disk utility after formatting as shown in the image uploaded here?
- Did the the system go through the usual 2-part Sierra installation?
- Did you run Multibeast on "Sierra Install" SSD in Legacy mode and install required kexts and System Definition, iMac14.2?
- Did you view the config.plist of the new Sierra System disks EFI>EFI>CLOVER>config.plist through Clover Configurator to confirm that in
- EFI>CLOVER>kexts>Other fakesmc.kext and your Ethernet.kext are present
- EFI>CLOVER>drive64UEFI has osxAptioFixDrv-64 or osxAptioFix2Drv-64.efi FSInject-64.efi, osxFatBinaryDrv-64.efi, PartitionDxe.efi, VBoxHFS-64.efi
- On "Boot" menu you did not do any changes, and in the
- "GUI", you made sure you have checked [] Legacy
- SMBIOS menu showed the System Definition to be iMac 14.2
- You made sure you could see your SSD in the BIOS in SATA -0 and the USB Sierra Installer?
- You booted on to the Clover Boot Manager through the USB Sierra installer for the last time
- Now you don't see in the Clover Boot Manager screen your Sierra SSD listed but still saw only your
- Sierra USB Installer and
- Boot from Clover EFI"
The Above happened even after you unplugged all other SATA devices and USB devices except the PNY USB and OCZ SSD?
I cannot think of any errors in your steps from SSD formatting to SSD Sierra System booting!
In that case, I have to suspect your Sierra installer may be missing some files.
In that case you may have to delete the already downloaded "Install Sierra" from Apple store and start all over again.
or use the SSD as a 'dual' Installer cum system disk sacrificing 16GB for the installer and the rest for System as has been shown in this post :
