Not a guide! -> moved to support section. A zipped copy of your OpenCore EFI folder with indication of the OpenCore version you use would be useful.

Is the disk visible in BIOS Setup? DU should show all disks, no matter the partitioning/contents. Maybe your SSD has gone faulty and that's what caused the OpenCore error rather than the other way round. I take it that your E6430 is fitted with 2 disks: one in the usual SATA slot and the other in the modular bay, right? If so, maybe you can try to swap them around to check things out. Then, it'll depend on which one carried the bootstrap of course. If I remember correctly, disks fitted into the modular bay required a patch of some sort to be seen in OS X/macOS.

Where is your macOS Ventura partition supposed to be? On the internal disk labelled ST500LM021-1KJM52? What is shown/listed when you select that disk? It would also be most useful if you could list what you did in terms of actions re: "updating OCLP". Was it just the config file you modified or did you update your OpenCore and/or OCLP version?

Congrats.

That setup suggestion with a SKL setup + dummy framebuffer id then a SKL framebuffer + screen sharing/VNC then OCLP really is most complicated when you can directly opt for a KLB framebuffer + a faked KBL GPU id from the onset. All details have been available for some time in old threads such as this one or this one; in other words, the exact same graphics settings that are to be used since Ventura which dropped official support for SKL graphics. All details available here. In a nutshell, simply use a KBL laptop setup.
