I have the same problem. The md5 of my .iso is correct and I have tried it on two different USB sticks. When I run "Check Disk for Defects" from the USB, I get "Check finished: no errors found".
The command that is failing ("Default") is:
/ubnkern initrd=/ubninit file=/cdrom/preseed/ubuntu.seed boot=casper quite splash -- presistent
On the other hand, "Try Ubuntu without installing" leads to a terminal login (whose default credentials I don't know):
/casper/vmlinuz.efi initrd=/casper/initrd.lz file=/cdrom/preseed/ubuntu.seed boot=casper quite splash -- presistent
