Deleting the disk/ hdd and reinstalling it

The moves on to reinstalling Big Sur

but like for the the 10th time, either gets stuck on 12/13 minuts left and or getting error code

”action couldnt complete. (Pkdownloaderror error 8)”

Also tried to use “command+option+shift+R”

Waiting a few minuts for the system to promt the setup menu to choose my language
Getting the macOs-help menu
Deleting the hdd- reinstalling it
Pushing first aid -no errors found
Trying to install New MacOs
getting this: Which says In Danish

”The Instsllation informations on the recovery server is damaged

Note I did many times try:

“command+option+R+P” and waited for the second bip sound to come on before relesing the power button.

Nothing seems to work.

Just wanna close this down and say i sent put bought a dongle type-c to usb and everything was fixed using a USB drive to reinstall that Way.

So anyone having same issues should go for the usb fix. Worked with ez for me.

So thx

to everyone who helped.

Have a good one, and stay safe.

You could try creating a Catalina or Mojave USB bootable installer on your iMac, then boot and install your MacBook Pro from that.

Thanks. I will for sure try that 👍

The thing is, i dont have a “dongle” Type-c to Usb to connect with as of now.

But i do have Imac, tablet, iphone and Windows pc 😁 and wifi so my hope was i did not have to spent more for something as stupid (if u ask me) as a type C to usb which i have no use for other than fixing and reinstall the MacOS .

I did just think of one thing. One of your screen shots shows it's trying to install Sierra. Sierra won't install on a Mac that was formatted for Big Sur. When you are in Internet Recovery, you have to choose Disk Utility from the Utilities menu and reformat using Mac OS Extended case-insensitive/GUID partition scheme.

Thanks! You are spot on, but just to launch the High Sierra installation the file system has to be correct- which is why i tried time and time again to “delete disk/hdd” and reinstall the filesystem gong between Catalina and High Sierra.

The error is relater to the “server on the internet” Were it says the MacOs is corrupted.

and i have no clue why either wouldnt work.

The drive it selvf shows no error messege what so ever and the internet connection is 100% fine..
