Tried to update operating system from High Sierra Monterey. No nothing works as it stops with less than one minute to go and freezers. I can’t open in safe mode. What do you suggest?

I tried to operate system upgrade to Monterey from High Sierra. Will not load and freezers at less than a minute remaining. Computer will not open in safe mode. Does anybody have any suggestions.

I managed to get to a reboot with control r. I then reloaded Monterey and started to install and again froze at less than a minute remaining.I’m leaving it for an hour or so to see if it finally takes this time. Thanks for your input it was helpful.

Yes, working well now. It took a few hours and just letting the machine run, restarting the loading and run again but eventually it got through.I didn't know about the control R function so was completely stymied. Also good for you to encourage patience as the system really did have to try a couple of times to completely load. Thank You!
