This normally occurs when installing an OS version which is unsupported for your hardware.

Start by providing a screen capture image of Apple -> About to show your hardware.

Then mention OS version you're trying to install.

Tip: If your Mac came with physical install media, it's likely you can't install latest OS version.

You can try installing an older version from the App Store. And same applies. You can only install an OS on hardware versions the OS version supports.

That's a kernel panic error. It can mean there is a possible hardware failure, but before you do that, probably best to try and resintall the original OS using the disk that came with the system.

Dear David
I am not able to get into the system when I boot it will start the boot process, and after go into installation mode you will see a time bar indicating some form of download with a time indicting, but it will never finish. So, in short, I am not able to get into the system to check the hardware specification. Is there a way to boot in a save mode?

Provide some history about how you got to this point.

You start by saying "I was trying to make an update from the internet".

This suggests...

1) The machine/hardware was working + running an older version of OSX.

Mention if this is true or false.

If true mention OSX version you were running, if you know the version.

2) You initiated either an update or full reinstall of some newer version of OSX.

If this is true, mention the OSX version you're attempting to install.

You may want to reset the SMC and PRAM before anything else. It's 2 quick "fixes" that can be done in a short time and frequently just makes it work.

Reset the SMC:
Unplug the power, then press and hold the power button for a few seconds.

Reset the PRAM:
Plug in the power cord.
Turn on the power.
Immediately press and hold command option p r
Keep holding until you hear it chime 3 times.  If you have a newer Mac, then you wont hear a chime.  You will need to pay attention to the screen and watch for it to briefly flash 3 times.

If your iMac OS X is new enough, boot into recovery mode by holding command r during startup.  If it gets into recovery mode, you can try to reinstall the OS.  If the recovery partition was destroyed, try Command option r to boot into internet recovery mode and reinstall the original OS X that came with the system.  If your system has a DVD/CD slot, you probably won't be able to do this at all.

Boot into Apple Diagnostics or Apple Hardware test (AHT) depending on whether you have a newer or older mac:
Turn on your Mac and immediately press and hold the d key.

https://support.apple.com/en-us/HT206886  Apple still has a download El Capitan (10.10) link.  http://updates-http.cdn-apple.com/2019/cert/061-41424-20191024-218af9ec-cf50-4516-9011-228c78eda3d2/InstallMacOSX.dmg

It might be easier to first reinstall your iMac, then download El Capitan and ugrade.

If your OS isn't running, you're going to have to download the OS on another computer, then extract the file and burn a USB stick first.
