Bootable USB only shows windows and not High Sierra drive
I have swapped my daughter's mid 2012 Macbook pro's hard drive with a solid state drive to help with performance. After doing this I am trying to install High Sierra from a bootable USB 2.0 stick.
- I have formatted the usb to Mac OS Extended (Journaled)
- I have installed the High Sierra installer onto the usb
- I insert the usb and then boot from it by pressing the option key after powering up the laptop.
- When the startup manager appears it just gives me the option of a drive named "Windows".
- I have reformatted this usb and re-added the High Sierra installer several times with no success
- I have tried to boot from the usb on other Macs but they all show the same
Below is a picture of the screen I get when I boot from the usb on another Macbook that is already running Catalina.
Is there something with High Sierra that I am not aware of? Am I missing a step? Any help would be greatly appreciated.
Thanks.
