Can't boot from OCLP 0.6.6 installer USB drive - CMP 4,1/5,1 OS X 12.6.6

[fzJNotIBOxgnbqejSeVCvJScL]

The latest OCLP appears to have damaged my boot partition. Did a delete/erase of my EVO 970 plus. Can't boot into recovery partition, getting a circle with a slash through it when i try to boot using the OCLP installer USB image.

What am I doing wrong?

Hard to tell - can you boot with an installer and show your drive layout in the hard disk utility?

I haven't used the newest OCLP yet but the EVO 970 rings a bell - it does have some compability issues with certain systems. Of course you have surely used it for a while now but remember OCLP is still "experimental".

I'm not getting the Recovery CMD + R option to work either. Always get the circle with the slash through it.

Can you insert a USB installer and boot with Option key?
This should give you a selection of boot devices - if not there is something fishy.

Be sure to try an NVRAM reset:
Restart, holding Cmd-Option-P and R.
You should hear the boot chime. Keep holding the same 4 keys until you hear the boot chime 2 more times.
Then, release the keys, continuing to hold the Option key.
At the boot picker screen, select the EFI choice, click the arrow under that choice. You should then immediately see the choice for your boot drive. Select that, and click the arrow underneath.
Should boot to your normal OCLP boot drive.
If that doesn't boot, insert your prepared USB OCLP installer drive, and try the same sequence with that drive in place.

Is the issue my NVMe drive? Please see the screenshot.

Anyone have any thoughts?

I think the filesystem or drive is damaged. There are read errors in some blocks.

OK, looks like I got it working. Had to tweak the settings in OCLP to allow for NVMe booting and disabled APFS trim. Not sure if that's the exact fix, but it's working now.

Spoke too soon. Ran the Migration Assistant to restore my files, and now I'm in a reboot loop.

Can someone tell me if we're able to run the Migration Assistant? or does that wipe out the EFI partition that OCLP creates?

I have successfully used Migration Assistant to restore my account and all it's files via a Time Machine backup on an OCLP deployment of macOS Monterey on my Mac Pro 5,1. So in this one instance I know Migration Assistant does NOT wipe or overwrite any of the OCLP stuff in the EFI partition.

Interestingly enough however, the reason I'm here is because I was trolling for an answer to your original issue. I too was suffering from the "prohibited" sign (the circle with a line through it). THANKFULLY your update on how unchecking the box that enabled "APFS TRIM" did the trick for me to finally get Ventura installed on my Mac Pro 5,1. And interestingly enough I too have a Samsung EVO 970 NVMe SSD. So something in that drive is "touchy" that APFS TRIM can't be enabled via OCLP.

...anyway, after fully installing Ventura I decided to use migration assistant again like I did for Monterey to see if I too have the issue you ran into or if I would have the fortune of succeeding again like I did with macOS Monterey.

Sadly I must report I too am now stuck in a boot loop and will be wiping the drive with a clean install of Ventura via OCLP so see if I can change what all I ask Migration Assistant to migrate to see if that makes a difference. 🤞😅

UPDATE: 06-25-2023 unfortunately, even if all I choose to restore is my user account and app instead of the system files and settings I still get stuck in a boot loop after using migration assistant with Ventura and OCLP (version 0.6.7) on my Mac Pro 5,1 😔
