Only reason why it would not show the HFS+ disc in that case would be that the disc is not bootable.
It is definitely a bootable disc. It was my main boot drive until I installed Catalina on another drive.

When I am in Catalina, system preferences recognized the El Capitan disc as a start up disc ans I can select it. So the OS sees it as bootable. But when I restart it always restarts to the Catalina drive.

Basically I can’t seem to boot back onto my El Capitan drive since installing opencore. It doesn’t “stick” when using startup disc and it isn’t “visible“ in the opencore bootpicker.

In other words, it's not bootable.

You must have somehow messed up some critical system files. Restore the disc from backup and be careful when moving or deleting stuff.

BTW, this has nothing to do with OpenCore and the fact that you noticed it after installing OpenCore is mere coincidence.
 
I don't have NVMe, this may be the reason.
I have Catalina on an NVMe. It takes 42s from chime to bootpicker (Catalina on NVMe set as startup disk). The performance gain I got from the NVMe is worth the wait if that is the problem. I don't reboot that often anyway.

BTW Is OC in the EFI on the NVMe? I couldn't get that to work - hard to do NVRAM reset every boot. Moved OC to EFI on a spare SATA disk and works fine.

Clarification: SATA are hard disks not SSD

If I physically remove the Catalina APFS drive from my system, the HFS+ El Capitan drive boots without any issue.

Also, using the apple option key boot loader with my old 5870 card I can see both the HFS+ and APFS drives and boot from either one. It is only when using OpenCore bootpicker that it fails to see the HFS+ drive.
 
@h9826790 beta 4 is released, for incremental update (or full install) I guess VMM flag is not suffice, do you confirm is required SMBIOS spoofing ?
This must be the beta 4... with VMM flag (and beta profile)

Also with sudo ./installinstallmacos.py --seedprogram DeveloperSeed --build 20A5343i

But not through OpenCore. Perhaps you could start by ruling out your Catalina drive by installing OC to a USB drive and see what appears in the boot picker with your Catalina drive removed.

look at the Scan Policy value in your config file. If it is the default value, then OC is not scanning for HFS drives. In the OC documentation section 8.5 Securities Properties, check for the Scan Policy values associated with all the drives and file systems.
 
Does anyone know how to display all external drives in picker? I once had my time machine icon there with external installs. Playing around I lost it and don't know what I changed to get it in the first place.

Update: Never mind. Found it.

yes only board-id. I only change the VMM flag for updates.

If you used a board-id spoofing (I guess the iMacPro1,1 board id) , this is almost equivalent to the SystemProductName spoofing, perhaps with board-id spoofing you don't need VMM flag for detecting incremental updates in Big Sur .
 
That's it, I only turned on the VMM, and disabled all spoofing.

I guess for detecting BigSur OTA updates (or from createinstallmedia USB Big Sur Installer) is sufficient a board-id spoofing on config.plist without VMM flag :
Code:
        <key>Emulate</key>
        <dict>
            <key>Cpuid1Data</key>
            <data>AAAAAAAAAAAAAACAAAAAAA==</data>
            <key>Cpuid1Mask</key>
            <data>AAAAAAAAAAAAAAAAAAAAAA==</data>
        </dict>


Code:
        <key>SMBIOS</key>
        <dict>
            <key>BoardProduct</key>
            <string>Mac-7BA5B2D9E42DDD94</string>
        </dict>

From my earlier test BigSur software update distribution file checks only for the supported board-id , while Catalina distribution file allowed also VMM "as board-id".

Hi guys, I've tried searching, but haven't been able to track down an answer to this. I just upgraded from 0.5.8 to 0.6.0, and now my boot picker opens in the following order:

1) EFI
2) OSX
3) RECOVERY
4) WINDOWS
5) EFI

I'd like to rearrange it, so that by default, OSX is the first option highlighted (rather than EFI). How do I rearrange the boot picker order? Is it possible to do so?

I decided to first try OpenCore 0.6.0 as I was currently on 0.5.9

For whatever reason, that fixed it. All volumes are visible again. ScanPolicy was set to "0" in both config files, so that didn't seem to be the issue.

Select your OSX drive in System Preferences -> Startup disk

Are you able to boot Catalina from a USB hard drive? I can see it in the boot picker, but it won't boot off it. OC 0.5.9.

It wasn't indeed. There must have been some other misconfiguration that was inadvertently fixed.
Glad you have everything back up and running.
Remember to always backup important stuff.

I don't have Opencore on a USB. I use a small SATA SSD plugged with the superdrive. It's not for any use but its EFI partition.

Can't help much with this but if you pick a startup disk in macOS the EFI drives will disappear. At minimum the open core EFI.

Sorry, I wasn’t clear. My Catalina install / OC is on an NVMe drive. I’m trying to boot a clone of Catalina from a USB hard drive, using OC’s boot picker, but it’s not working. i Just wondered if during your experiments with the boot picker you had tried booting the OS over USB.
