Strange thing during Monterey install

[rimvydukas]

Hi,

Tried to do clean installation of Monterey. My partition layout is the following:

Tried to install to MacSSD volume (deleted volume group with system and data volumes and created new MacSSD volume). Installation started and my mac was rebooted at the end of it. Started to boot up and ended with the following message:

I guess, this is happening because I have my UserDataSSD volume in the different partition. And it seems this is something new in macos installer as I was able to install Big Sur with the same partition layout countless of times in the past.

So my question - anyone knows something about these new changes? Is it possible to install Monterey with my existing volume untouched? Or maybe we'll be forced to say bye bye for multi boots?

So long story short. Apple senior advisor called and explained that such partitions layouts will not be supported anymore:/ Advisor only was able to tell "not supported" and thats it, no articles, no clarifications, nothing. This Apple support is pathetic So, I guess, at least for now, we may say bye bye for dual boot systems on the same internal disk:/ Please, send feedback to Apple, if you feel bad about this.

One more update after Monterey 12.1 release. I want to report that actual problem has gone with 12.1 release, I'm more that happy.
