1) Boot from USB as normal.
2) During Resident/Guest mode selection, press 'TAB'.
3) Add "INSTALL=1" to the end of the command. Press 'ENTER'
4) Follow on-screen installation steps to perform full install onto local HDD/SSD.
5) You may need to perform the IMGTools hack to enlarge your data.img storage size, because it caps out at 4GB, even if you installed onto a large HDD. I enlarged mine to 256GB (274877906944 bytes) with no issues.
