My pc is Lenovo.. when i click the on button.. it won't start.. can't enter the boot menu

Repeatedly tap the F1 key when the Lenovo, ThinkPad, ThinkStation, or ThinkCentre logo appears, The computer may beep once to indicate that it will boot to BIOS.

How to Enable Boot device List F12 Option The following example shows a system that has an option to enable or disable the Boot device List F12 Option.
Go into the BIOS to enable Boot device List F12 Option (option is usually under the Startup tab).

This can depend on your OS. For slower booting systems, press and release F12 repeatedly after pressing the power button. Release the button when you see the Choose Boot Device screen. Select the boot device and press Enter. (Note: some systems may not boot from all USB devices or CD/DVDs if they are set for a type of secure boot (UEFI).)

With some systems, you may need to enter the BIOS setup utility to allow the system to boot from a specific device. Try pressing F1 repeatedly after pressing the power button until you hear a lot of beeps or a splash screen. If there is a password for the setup utility, you'll need to enter that password. If you reach the Windows lock screen or the desktop, you missed the timing. Under Windows 10, go to the power icon in the Start menu (on the lower left). Press shift and click Restart. You will see an option for entering the BIOS on restart. Select this and wait. Once in the Setup utility look for the boot menu. You can change the order of the list. Press the correct buttons for save and exit to boot to the desired device.

I hope this helps.

(Note: some wireless keyboards may not work in the setup utility. Make sure that a wired keyboard isn't plugged into a USB 3.0 port if you need to load a USB driver to enable the port.)

Hi
It sounds as if the hard drive in your machine has lost the ability to boot the machine up. If you can boot from a bootable CD/DVD or bootable USB drive if these options are available from the boot menu, then this confirms the hard drive has problems. Try using the "Lenovo button" just to the right of the Power button to see if you can return the computer to previous settings the worked. Be wary though as choosing the "restore to factory settings" option will lose all the data on the hard drive, and should only be used if your data is backed up properly, or in utter desperation.

Yes, supposedly just to the right of the power button Upper left
Novo button
When the computer is off, press this button to start the
Lenovo Recovery system or the BIOS setup utility, or to
enter the boot menu.

1 Press the Novo button to start the Lenovo OneKey Recovery system.
2 Click System Recovery. The computer will restart to the recovery environment.
3 Follow the on-screen instructions to restore the system partition to its
original status or to a previously created back-up point.


If Windows cannot be started, follow the steps below to start the Lenovo

2 Press the Novo button. From Novo Button Menu, select System recovery

Lenovo Basic Input/Output System (BIOS) settings allow you to quickly customize interactions between your operating system and your hardware, especially your hard drive or drives, memory and power supply.
You must get into the Lenovo BIOS before your operating system loads.
Though most users don't typically see options for entering or using the BIOS, multiple changes can be made to customize and optimize your system, such as changing your boot device order and changing the display brightness to conserve power.

Turn off your Lenovo computer.
Press the power button to start your system.
For best results, wait 30 seconds to one minute before starting your system.
This gives you a longer window in which to enter the BIOS.

Press "F1" as soon as the Thinkpad logo appears.
Depending on your Thinkpad model, you may be prompted to press either the blue "Access IBM" or the blue "ThinkAdvantage" button instead of "F1 or F2."
If this is the case, a message will appear stating "To interrupt normal startup, press (one of the listed buttons above)."
Select the "Start setup utility" to open the BIOS setup menu.
Follow the instructions provided in the BIOS setup menu to select BIOS menu sections, settings and to change options.
Next, navigate through the Bios setup pages using keybard arrow keys in order to find failsafe or optimized defaults press ENTER to select your option press F10 save to cmos and restart

enter the bios usually f2 or del pressed immediately after turning the laptop on, also look for something on the screen saying press f11(or some other button) to enter boot menu

if you have the boot menu option then you can choose to boot from cd/dvd and windows 7 will load, if you havent you will need to enter the bios and change the boot priority to boot from cd/dvd first

if this helped please vote

Welcome to Fixya

Try to do system restore first on safe mode. Turn on the computer and keep on tapping F8 key. Select safe mode and press enter. Once you are already booted up to windows safe mode, click start menu then click all programs. Click accessories then click on system tools. Click system restore then choose a date where you remember the computer is working fine. Restore the computer to that date.

Thank you for usng Fixya!
