Installation problems with 18.04.2 LTS

Question

If the OEM install is used, the install to disk and boot from HDD works properly. Normal install fails to boot from HDD after install. What is the difference between these two install options?

Answer 1

Gave up on 18.04LTS. Downloaded Ubuntu Studio 19.04, burned to DVD, installed from DVD and booted from hard disk first try ... 18.04LTS install scripts have bugs!
