Summary0005922: Unable to boot from USB stick
DescriptionHello dears,

  I'm trying to install CentOS 6.3 from USB stick onto new server (supermicro).

  i've just downloaded CentOS-6.3-x86_64-netinstall.iso and instaled this image onto USB stick via livecd-iso-to-disk tool. This proceed on another CentOS machine running CentOS 5.8.

Now, when the new server boots, this message is displayed on the screen:

unknown keyword in extlinux.conf

no line/typo identification, nothing that could help me to resolve the problem (i.e. edit the extlinux.conf on usb stick and remove 'unknown keyword'), the boot process stops.

Trying to search the Net for some solution, unprevailing :(

Any advice would be appreciated

Steps To Reproduce- download CentOS-6.3-x86_64-netinstall.iso OR CentOS-6.3-x86_64-LiveCD.iso (no matter - both ends with the same error) from official mirror (VUTBR)

- install it on usb stick

[root@jen mnt]# livecd-iso-to-disk --reset-mbr CentOS-6.3-x86_64-LiveCD.iso /dev/sda1

Use UNetbootin, it's the best for this kind of stuff
