I am using TI8, build 786 on a Motorola MW-520 mobile data terminal running Win2000 professional, SP3. I have been successful creating the Bootable Media on a SanDisk Cruzer Mini 128mb USB thumb drive. The problem is whenever I try to boot from the SanDisk Cruzer Mini, I get the message "Operating System not found" and the computer stops right there. I've tried creating the bootable media using both Full and Safe versions, and also in normal and safe windows mode. Has anyone else heard of this problem ?
