Garycase,
Thanks for replying - Yes, I did run the "MakeBootable" utility and it still does not work.
Franck1940,
I did try all BIOS setup options and it still did not work.
I decided to upgrade the BIOS from version F1 to F7C and the flash drive is recognized and now I get a message below.
SYSLINUX 6.03 CHS 2014-10-16 Copyright © 1994-2014 H. Peter Anvin et al
Failed to load ldlinux.c32
Boot failed: please change disks and press any key continue.
It looks like I have to run the mkdiskimage utility to see if this fix the issue.
I now have a 16GB flash drive and I was wondering this command below would work for drives larger than 8GB?
mkdiskimage -F -4 /dev/sdz 0 255 63
