iMac 5K Mid-2017 error while trying to update to Mac OS Ventura

[maorattias]

Hello everyone,
I have iMac 5k 2017 that I bought last august from someone.
the iMac couldn't be updated and couldn't install any Mac OS.

I bought new transcend 1tb ssd and I did something different.
I took my mid 2015 MacBook Pro and connected the new ssd with sata to USB adapter and plugged it into the MacBook.
I also took usb stick and installed bootable Mac OS Monterey installation on this stick - why Monterey? because Mac OS Ventura didn't worked when I tried to install it.

next, I restarted my MacBook Pro and pressed alt to run my new bootable usb with Monterey installation.
then I installed my os Monterey through my sata to USB adapter on the transcend 1tb ssd.
the installation done perfectly.
after all of this I connected the new transcend ssd with Monterey installation into the iMac sata cable inside.
the installtion on the iMac 5k worked perfect.

but now, I'm trying to update the computer from system preferences to Mac OS Ventura and I'm getting everytime this error:

"an error occurred loading the update"

I heard from someone that maybe my firmware didn't updated - is it true? if yes, how can I fix it?

please help me solve this problem.

thank you everyone.

If your firmware needs updating, you can try to install each version of macOS in succession. Start by downloading High Sierra on your MBP and create a USB installer. Boot from the USB installer on you iMac, use Disk Utility to erase the disk, and install High Sierra. You can use the Mist application on your MBP to create the USB installer.

OP:

Try this:
1. Start from "power down, all the way off"
2. Hold down "command + option + R". DON'T LET GO OF THESE KEYS
3. Press and release the power on button. KEEP HOLDING THOSE KEYS DOWN
4. If you're asked for your wifi password, let go of the keyboard and enter it.
5. After a while, you should see "the spinning globe" that indicates the internet utilities are loading. Do you see it? NOW let go of the keys

6. Can you get to the internet utilities?

Try this, then come back and tell us what happens.

now what should I do?

"now what should I do?"

OK... I'm going to assume that there's nothing on the internal drive that you need to save.

Do this:
Go back to internet recovery.

Click on disk utility.

VERY IMPORTANT:
Go to the "view" menu in disk utility and choose "show all devices".

Now look at the list "on the left".
You should see the internal drive listed, should be "the top line".
We want to ERASE it and start over.

Click "erase".
Choose "APFS, GUID partition format".
The erase shouldn't take long.
When done, quit disk utility and open the OS installer.

ACCEPT ANY VERSION OF THE OS THAT YOU ARE OFFERED.
Reason why:
A Mac that boots, is better than one that doesn't.

Start clicking through.
The Mac will restart one or more times, and the screen will go dark for a minute or more with no other indication of activity. Be patient.

When done, you should see the initial setup screen (choose your language).
At this point you can start clicking through.
Either create a new account, or, if you have a backup drive and want to migrate your stuff over, follow the instructions in setup assistant.

Good luck.
