no root device found.
booting has failed, sleeping forever.
Above is the error you may face with Fedora 12 / 13 Live CDs, this appears with specific hardware, Whereas same Live cd / usb works fine on another laptop / desktop. Most of the time it appears if usb / cd is not configured as first boot device & boot sequence is changed while booting using Function key.
This is the error I usually get on my HP Compaq 6710b laptop.
Following is the only solution seems working.
In BIOS setup enable USB / CD device as first boot device.
Or try changing boot device order.
This is all you need to do, now you’ll be able to boot using Live CD which was throwing error on same hardware.
this is intermediate problem.
