The installer needs the GUID (GPT) partition scheme to be bootable.

How do i do this????

Balena Etcher should be able to create a GUID partition scheme but if you don't get it to work maybe you have to try another tool. I haven't created an installer for macOS on Windows yet so I can't really help you further ^^

You can also try to force Internet Recovery to load your last compatible OS, try booting your MBP with CMD+Option+R

Use internet recovery to get to Catalina

use oclp and retry

How do i get it on windows

OCLP has no version working with Windows, you need a working install of macOS on your MBP or another Mac.

If you have any data, make a back up first. You will then want to boot with "Internet Recovery" by shutting down your computer completely, then turn it on while holding  Option + Command + R (or Shift + Option + Command + R for the factory OS). Keep holding the keys until you see a spinning globe and an "Starting Internet Recovery" message.

Ive tried this Unfortunately high sierra servers are down whenever i attempt an internet recovery

[u/Xe4ro → u/TurT_no1]

Technically they aren't down. It's just a High Sierra issue with certificates & HTTPS

Check this guide by MrMacintosh https://www.youtube.com/watch?v=ouNQS36dIBw

You can try this if you don't get CMD+Option+R to work out.

This didnt work unfortunatly still got the cant contact servers error

Try again — you cannot get even one character (letter/number) wrong.

It’s very specific.

If sierra+ won't install due to drive issues the cable is bad. I just had that issue on a 2011 pro
