iMac OS install failing

I booted into Recovery mode and tried Reinstall macOS Sonoma on my iMac and it goes through the 2h+ process and then reboots. At reboot it shows the progress bar and barely starts and then reboots again? I don't know where to start troubleshooting this issue but I've done the macOS install twice and it has the same results.

Reinstalling MacOS Sierra Problem (failing in the last 2 seconds) Hello everyone, Recently I purchased an iMac from my university's surplus auction. Part of the policy is to wipe the HDD/SSD of any machine they decommission. Currently I am in the process of reinstalling the OS from Recovery following the instructions here: How to reinstall macOS - Apple Support My machine has an intel cpu: i7-7700k so I followed the intel based instructions. Because the system could not see the disk I followed the instructions for erasing my disk here: Use Disk Utility to erase a Mac with Apple silicon - Apple Support After I did that (renamed the drive to Macintosh and then formatted it using the Mac OS Extended (Journaled) option) the installer could see the drive. The installation started normally but then in the last 2-3 seconds the installation keeps failing giving the following message: "An error occurred while preparing this installation. Try running this application again." I have tried the whole process of erasing and reinstalling mutliple times. I also made sure the system clock is in sync with time.apple.com. Also the whole installation is via ethernet and not wifi. The OS version that is to be installed (automatically) is MacOS Sierra. Any suggestions as to why this is happening and how I can potentially fix it?

HELP! My 27" Intel iMac Just Blue Screened... My 27" Intel iMac just blue screened and no longer loads passed the progress bar, before it reboots again and again. Any tips you can provide would help tremendously, like alternative ways to reinstall the OS without losing files, for Cmd + R and Option + Cmd + R options don't work. The latter option loads all the way to the spinning earth globe, but then reboots again and again like the Cmd + R. Please help asap for my business has come to a screeching halt because of this, so I'm losing money every day I can't access my 8K plus clients. Thanks, Paul
