  STEP 1. Select "F2" on your SCREEN black Error Message 'diskette drive 0 seek failure;

       Missing the 2nd step indicating where 'Floppy' must be DISABLED... is actually in two places.

  STEP 2.  Arrow down and SELCET «CMOS...» "near the top of the list - (the keyboard is not active) and on the next screen, arrow down and SELECT -" Floppy Drive-1, 44 is activated "MUST be EXCHANGE FOR: 'DISABLED' (the readers of floppy-1, 44 are obsolete) another menu screen will pop up, to make your selection, the arrow down to select"OFF"and the ECONOMY-F10.

  STEP 3  Submenu will return to the MAIN - BLUE SCREEN Menu, you need to arrow down and select BIOS; as stated in previous POSTS and need RESET BIOS to: #1 HD, CD/DVD #2; #3 unable to READ floppies; then select F10 to run, return to the main Menu of previous blue screen; "F10,"saves and exits" you in the main Menu of Blue SCREEN" toCOMPLETE FIX... Windows Start Up, immediately, translates the computer starts normally and returns to theWindows Logo and connection status. 

  • (See this correction, corrected an error in the boot order in the BIOS since the 'HD' has been 'DISABLED', floppy drive was 2nd "Enabled" and CD/DVD has been 1st disk "Enabled"; and CMOS had "activated" "Floppy drive-1, 44" that has generated this ERROR BLACK SCREEN and interrupt thenormal Windows process at startup computer n and connection.

  This is my new tablets...

  (Sorry for my bad engglish)

  Hi Grenven,
  Do what I say to reset (restart) your Tablet: -.
  --> Memory location opened by card (SD card).
  -> Take something thin and sharp as a safety pin or a toothpick.
  -> Now, you will see a small hole like structure near SD card slot. (In fact it looks clearly if there is something on the inside, but there are.)
  -> Spend your pointy thing in this hole up to a certain distance. (Pass slowly inside until you hear a clicking sound)
  -> Who has the reset button which will restart your tablet of any situation.
  -> Do not lose patience while finding the reset button. Do what I say and your tab will be back normal. Find it for the first time is a little more difficult but follow my steps, and you will get it.

  Good luck...!!

  Andy1502_a,
  If you haven't tried the "last known good configuration" among the Advanced startup options then do that first.  If this does not help, you must run the System File Checker to search for possible system problems.  Then, you must run the upgrade from the system tool and then see if you are able to run the SP2 update.   Mike - Engineer Support Microsoft Answers
