This was a BIOS settings issue.
In the BIOS of this Asus netbook I found a second setting, which also had to be set with "USB" as 1st boot device.
When I found this setting, the 'Boot Settings' dialog box had the following categories:
"Boot Device Priority".
"Hard Disk Drives":
It was necessary to additionally set "USB" as 1st boot device within the "Hard Disk Drives" category.
In here its default settings were:
"HDD"
"USB".
its called a "boot-up"
COLD BOOT - Booting up from power off condition.WARM BOOT- Restarting the computer WITHOUT turning the power off.http://wiki.answers.com/What_is_the_difference_between_cold_and_warm_booting#ixzz18HVIBp79
While booting, a computer looks at a number of available disks (floppies, CDs, harddisks) to see if they contain a bootable operating system. Older PCs would always boot from the harddisk, unless a floppy was present, and if that floppy didn't contain an operating system (like DOS), it would give this error message so you could remove the floppy and the computer could go on booting from the harddisk.

warm booting
Warm booting refers to when your computer is already on and you do a Restart to the system. This is also called soft booting.
Cold booting occurs when the electrical power (the switch button) on the system unit is turned and warm booting occurs when the computer system restart or reset without turning off the power.
boot to a safe mode
A computer does not need to have any input or output devices plugged into it at all in order to boot, as long as it is configured to not stop on missing devices; the most common "stop error" for missing devices is a keyboard, and this can typically be disabled.
MBR Master Boot Record. I think so because one of my oracle professor told me that master boot record is the source to the windows booting setup. not confirm i think so.
When the cable box says "boot", it means that the cable box is booting/re-booting. Don't do anything yet, wait until the display goes blank, then in a couple of minutes, the time will appear.
