This error comes up if the computer is not able to detect the hard drive. Power off the computer. Power it back on and tap the number 2 key 4 - 5 times at the Dell logo screen. This will take you to the system setp screen. Check if you see any thing listed next to solid state drive. If you dont see any thing try reseating the hard drive. Here are the steps to reseat the hard drive..
If you see an entry next to the solid state drive. You'll need to reinstall windows on the computer. If you have been shipped XP you will need an external CD drive to reinstall windows. If the system was sen with ubantu try to download it to a usb drive and boot off it.
Rate if useful.

The problem your having could be the operating system is damange or the hard drive failed. Try to boot from a Windows XP or Vista CD to see if the drive is recognized.

hello, sounds like bad hard drive. here is what you can try, go in to BIOS and reset it factory default save and exit, let the system start again go back in BIOS and check to see if you see your hard drive there, also this time disable Boot from Network option. seeif your system actually starts up... or you get "no operating system found", if you saw the HDD in BIOS and get no operating system found, you can try reinstalling windows.
if you still media test failure and it loops, you need a new hard drive.
let me know if it helps...

SOURCE: I have Dell latitude E5420.
make sure your operating system is updated thoroughly (go to START, WINDOWS UPDATE)
once you have done this go to this link below, download the AUDIO drivers & BIOS driver
once this has been done, go back to the link and download all applicable drivers dated for 2010 or 2011. Once you go through all these drivers, it should resolve UNKNOWN device issue.
download and save all drivers, then execute them one at a time.
hope this helps you ! if so , please send me 4 thumbs up

click start control panel hardware and sound manage audio devices right click on your speaker select configure speakers
right click on the speaker icon in the bottom taskbar you will see an array of options playback recording sounds and communication select playback devices make sure it has a green tick have a look through all of these make sure all are configured properly
and the correct speakers are selected
be updated if you computer came with a motherboard disk the drivers
could be on it although once speakers are connected widows 7 should automatically update the drivers
click start control panel hardware and sound manage audio devices playback you might have to set a default go for via high definition audio then right click on speaker

if this fails to fix the problem take it back to the place of purchase if possible or ring them for some warranty advice
it might be a faulty sound card
