Many tries - many errors, much searching, remain clueless... Acer Aspire E5-575 (I can use F2 to get into the BIOS) Trying to: Install Ubuntu Zesty Zapus 17.04 from USB continually get error: Default Boot Device Missing or Boot Failed. after "successful" installation I can run Ubuntu from the USB and have started Gparted and get this: The driver descriptor says the physical block size is 2048 bytes, but Linux says it is 512 bytes. Potential problem may be from this observation: I pulled out the flash drive just as the re-boot started and got all sorts of errors (about 15-20) the first of which says:

[     0.218737]  platform MSFT0101:00: failed to claim resource 1

further errors indicate it's trying to read sda where the OS was installed on /dev/sdb.

  • We made many Ubuntu installs, which failed to boot.
  • Finally, in BIOS we did "Security > Restore Secure Boot to Factory Default". We reinstalled Ubuntu; it still failed to boot. Then in BIOS, "Security > Select an UEFI file as trusted for executing", we kept on HDD0, selected , and set "grubx64.efi" , "Wish to add this file?" to YES. [F10] Save and Exit. THAT booted up into Ubuntu (17.04). NO reinstall was required.
