Big Sur beta 2 install from USB HP 800 G1 Elitedesk Haswell

Steps I used to create a Big Sur USB installer


Gathering items

16 GB USB drive
240 GB SSD (Big Sur is too slow on a spinner)
HP 800 G1 EliteDesk or Haswell based computer
My EFI.zip file to boot Big Sur
Clover Configurator <- used to mount partitions
Time and patience

I have a HP 800 G1 running Catalina/Big Sur, this is what I used to create the USB boot disk with Big Sur beta 2.

Step 1: download Big Sur by pasting the below link in terminal, select the Big Sur Beta 2 download.

curl -O https://raw.githubusercontent.com/munki/macadmin-scripts/main/installinstallmacos.py && sudo /usr/bin/python installinstallmacos.py --raw --seedprogram DeveloperSeed

Step 2: Format your USB drive with Disk Utility with GUID Partition and call it Untitled

past the below command in terminal to create your USB installer

sudo /Applications/Install macOS Beta.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled

Once that is complete, use Clover Configuraor to mount the EFI partition on the USB installer, copy the EFI folder from my zip file to the USB UFI partition.

if all went well, you should have a bootable USB installer.

Step 3 coming.. getting tired...
