Hi all,
Thanks in advance.
I tried to perform a clean install of MacOS High Sierra on my 2011 iMac 27" (EMC2429) using these instructions* (created a bootable USB); however it's been failing. Specifically, after erasing the "Macintosh HD" it tried to install Sierra from the bootable USB disk but prompted this message:
"macOS could not be instead on your computer. The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged."
I then followed a few of the tips and guides on here:

I launched Disk Utility and see that the HD is still intact since it lists my "Macintosh HD" in Disk Utility.
I also tried to Restore via Time Machine, however I left it running overnight and it still isn't working.
I then decided to create a bootable USB of MacOS Sierra but booting from the USB didn't work either.
I also found this person's Medium post, but I couldn't seem to launch Terminal once I was in Disk Utility:

Any one else having the same issues as I am? I am almost tempted to just rip out the old HD and installing a new one but it seems quite tedious and not sure if how I can load the macOS in the new HD before installing it.
