Big Sur - OS X Drive does not appear in the opencore boot menu

[artroeb]

I tried to install big sur on NVMe SSD samsung 970 EVO I got a problem OS X Drive not appearing in boot menu opencore 0.6.0, so I can only enter Big Sur by preboot only :


I also got a problem, I can access the big sur folder but the disk utility shows that the partition is unmounted and cannot be mounted:


Another problem is when I want to select startup disk Big Sur partitions are missing and sticking out continuously, so I can't assign a startup disk se my short video:

It's very different when I install on a SATA SSD, the OSX drive appears in the boot menu and disk utilities and startup normally.

I attached the config for Strix B360-I. is there something wrong with me or lacking in my config?

This is a bug in the beta. It's been discussed before, and a quick fix is to install Intel Power Gadget. When you specify the install location (ie., you system drive) it will correct the name.

But then someone said not to install Intel Power Gadget!

So this is a detailed fix that doesn't involve installing any software:

Big Sur Doesn't Mount Hard Drive Partition

Any clue on why just can boot from reboot and the Big Sur system doesn't mount the main Hard drive partition? on OC6

Yes I fix With IPG, it's faster than the manual method on that link. With IPG automatically creates a label partition for big sur on preboot and renames the volume in the OC boot picker (so if we boot via preboot it means the same thing).
