I have a working HighSierra-Clover-Setup running on a NVME-Drive.
I installed Big Sur via OpenCore (USB-Stick) to a separate SSD Drive.
During installation process -> reboot loop.
I removed the USB-Stick and the separate SSD.
Now I'm not able to Clover-Boot my old High-Sierra-Partition. Clover always boots a recovery partition.
Even on a mirrored backup-drive. Same issue. Clover shows drive selection screen and when I select the High Sierra Partition, the recovery partition is booted.
Thanks for any ideas or hints!

Problem solved. OpenCore "destroyed" the UEFI boot entries (checked with > bcfg boot dump at UEFI shell).
Removing wrong entries didn't fix it, but CMOS reset fixed my problem.
