BigSur install loop.... i was running well on 6.0 oc final catalina build ... tried to update to Big Sur via oc 6.3 USB drive. I was able to boot ok from usb though i lost my aquantia 10g ethernet and my usb stuff was acting up. So i updated my nvme drive and was able to reboot into catalina ok on 6.3 just with missing USB and ethernet. I decided that could wait, i ran the big sur installer which would run through the normal text message along bottom of apple logo etc and reboot where i would choose the installer and keep going. Here is where i died. The original entry for the catalina installation is gone only the installer shows now, if selected it runs the bar up about a quarter of the way and reboots never going any further. I can load the recovery image and it lets me run disk utility and it says the macOS and associated data partitions are good. It will let me install big sur again but at the conclusion i'm right back at the installer disk icon with no "macOS" partition .... any ideas ? I have unplugged all external drives, internal drives etc and no change. I don't understand how it shows the disk ok in the recovery utility program but won't let you select it inlace of the installer. I can boot from a catalina backup external nmvme disk i'm just not sure how to at least get back to latest catalina.
