enter 'help' for a list of built-in commands

i search about this , often says this a hardware problem ,
( i test this in 3 different pc )
for example :
1 - says unplug hard drive and cdrom ( IDE's ) from pc and try : tried but not successfull
2 - says when first page on booting press F6 and type after -- :

all_generic_ide

i tried this , but not successfull

3 - after i pressed F6 , i delete " quite splash " for view all jobs , but still give me same error ( busybox ) , but i take a photo from monitor , you can see here :

Hi
Even I am facing the same problem. I did everything as mentioned in the pendrivelinux site. Also, I downloaded the initrd file too. Still I am getting the error as shown by the posted jpg file. I checked the casper.log which says : init .... no media found in /dev/scd0 something. I even kept a cdrom (ubuntu live cd) but same error. BTB I am using ubuntu 8.04.1

Hope some body can help. The livecd works great. I have a toshiba a100 sattellite 2214 laptop. All the hw is detected perfectly. The laptop has Vista Business. I dont have much HDD space. So I thought ubuntu on USB will be of great help. But I am really stuck
