You do not say what exact Mac /model /year /size /retina /touchbar is this
or
what exact macOS you are currently running?
This sounds like a corrupt download or you do not have a machine that supports the latest macOS.
You can delete it, empty the trash and download a new Catalina macOS.
Verify your Tech specs that you have the hardware capable of support the Catalina—

I am having the same exact problem after trying to install Catalina on a late 2012 iMac 27" retina display. I see "mac OS could not be installed on your computer, A disk with a mount point is required: (-69854). The only option is to restart the computer and try again but it comes to the same spot over and over. I did find a way to get into the disk utility to verify the HD and it doesn't find any issues to repair. I have also tried to go to the Startup Disk, but when I get to the window asking to "select the system you want to use to start up your computer," there is nothing there. I feel like the only option I have is to completely wipe the hard drive and reinstall the OS from the web, but I'm hoping to avoid that because I would like to find a way to recover the information on my hard drive. Any thoughts?
Same issue. 2017 5K Retina iMac running High Sierra. Attempted to install Catalina using Opt-Cmd-R. "A disk with a mount point is required. : (-69854)". Ran Disk Utility Repair on everything showing - all completed with no errors. Tried to install again from Opt-Cmd-R. Same error. Can't reach Apple Support.
Hi per275,
i just tried to upgrade to Catalina this afternoon and I had the same issue. The install stopped and gave me an error message that said: A disk with a mount point is required (-69854). Out me in a loop and cannot boot anymore from my Macintosh HD. Did you ever find a solution? Any info would be much appreciated. Thanks much!
