So I am trying to make my usb stick bootable and load ubuntu 14.04 64 bit on it. I have tried different methods, for example, I format my usb on windows to be FAT32 and then am using the Universal USB installer loading iso file into it. However, I am getting 192 errors ! which most of the look like Data error in boot\grub\x86_64-efi*.mod. File is broken.
I also have boot the usb stick in different format, but still no success. I appreciate any comment.
the iso file I had was some how corrupted ... so I downloaded a new one and then it worked fine. thanks @Raphael
