    UEFI bioses have been evolving over the last couple of years. You might check to see if you have a recent bios upgrade. Whether you upgrade it is totally up to you.

    What logo appears is probably a result of the Bios and maybe your settings. I have one system that is currently showing the Windows 8.1 beta fish covered by the Windows 8 symbol. My other system now shows the ASUS graphic where before a recent update, it showed the Windows 8 graphic.

    Most laptops will show the OEM name in the Bios Screen on boot. Old Bioses will allow you to shut that off to see the boot process.

    Do you mean, it totally replaces the Windows 8 Boot Screen (With the rotating dots)? The first thing you should see is LENOVO in huge letters, then the Windows 8 boot screen with the round dots.

    But if you have a BIOS update available, I would do it. You can always restore the old BIOS if you don't like it.

    the pic of disk management is shown.

    now i cant even access my Bios settings at start up . F2 is used to enter in the bios but now even if i hit F2 , nothing happens. i want to revert back to old bios since i don't find any " UEFI" update on lenovo site . There is an update available but i think its for "legacy bios" because when i run it system just stop working it hangs... not even mouse moves...

    now what should i do enter bios and revert back to old bios.....

    Can you press the Delete key at startup & get into bios ?

    or

    Alt + F-10 ?

    Or get into Advanced startup to change Firmware settings ?

    The EFI System Partition would indicate to me that Windows 8 was installed in UEFI mode. My UEFI BIOS laptop has that partition, my desktop PC with normal BIOS does not. If it is UEFI you should be able to do this, UEFI Firmware Settings - Boot to from inside Windows 8 Now if that doesn't work try turning off Windows 8's fast startup , Fast Startup - Turn On or Off in Windows 8 Your PC may be going into a hybrid sleep mode instead of actually turning completely off. That can make accessing the BIOS on boot difficult of even impossible.

    With UEFI BIOS the Windows 8 Logo (the blue box) that is displayed above the circling balls on the Windows boot screen, can be replaced with the manufacturers Logo. On my Laptop I see an ASUS Logo. On my old desktop with just a standard BIOS I see the Blue Box. This is some thing separate from the BIOS Full Screen Logo.
