MacBook Pro I9 won’t boot past login status bar

Question

MacBook Pro I9 won’t boot past login status bar

i updated to the latest version of Mac OS on my Intel Mac book Pro. When restarted, process halts, with status bar at mid point.

i have tried the command r routine. Disk is good, reinstall OS - numerous attempts

estimate to install have ranged from 2hr 33 minutes to 12 hrs- all on high speed wifi. All ended in failure- currently trying again

estimate now 29 hrs.

Tried to install from Time Machine backups on external harddrive- failed. 2tb ssd is into two partitions - one Mac the other boot camp windows.

The bootcamp partition boots successfully into windows 10.

now how to get my MacOS to reinstall or boot?

how to download and install on external SSD or stick( only can access Boot camp windows to get download)

suggestions

thks Steve

The link is to Apple Support "If your Mac starts up to an Apple logo or progress bar"

Here's a screenshot,

The links in the screenshot won't open another site, so you'd have to go to the original site at Apple Support.
