That's odd, that the internal shows up as sda. However, the obvious two
things: first, and esp. if the systems sees the internal as a, is that
this won't work. at all - the grub entry is completely wrong - assuming
that's a grub.conf. If so, you want
title CenOS 6.4 Live
root (hdx,0)
kernel /CentOS-Live/isolinux/vmlinuz0 root=<huh0> <huh1> NO_LVM
selinux=disabled <huh2>
initrd /CentOS-Live/isolinux/initrd0.img
Notes:
huh0: are you sure that's the actual UUID of the flash drive? You might
check /dev/disk/by-id
huh1: Not familiar with nodiskmount
huh2: Dunno bout the live_dir... does a quick google...OH! Of course it
won't work - you're using
grub2, which CentOS doesn't support yet (and I hope NEVER, EVER
WILL).
