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
