Original post : Accessing the Advanced Boot Options menu.
"Advanced Boot Options" is a menu that can be displayed before Windows starts, providing access to various recovery options useful in attempting repair and recovery of damaged or incorrectly configured Windows PCs.
The "Advanced Boot Options" Menu
Depending on what version of Windows is installed, the Advanced Boot Options menu may or may not have certain options. This menu should be seen as a is part of (or an extension to) the bootloader. NTLDR or BOOTMGR present the user with the Advanced Boot Options menu and then start Windows with the correct parameters as selected. For details about all the various components of the Advanced Boot Options menu, please refer to the knowledgebase article
on the Advanced Boot Options menu
Accessing the "Advanced Boot Options" menu
It can be tricky to correctly access the Advanced Boot Options menu. Correct timing is crucial. The steps below should serve as a general guideline for gaining access to the Advanced Boot Options menu and its contents.
Starting with a fully powered-down computer, follow the instructions below:
Fully power down your PC and make sure it has come to a complete halt.
Press the power button on your computer
and wait for the screen with the manufacturer's logo to finish
. While the manufacturer's logo (HP, Dell, Acer, Samsung, Toshiba, Lenovo, etc) is on the screen, your system is undergoing a self-test known as POST in which it identifies connected hardware and brings it to a functional state.
As soon as the logo screen goes away, begin to repeatedly
press and keep pressed) the
key on your keyboard. Important note: for some laptops you may need to also simultaneously hold down the
key as well.
Windows loading screen
shows up, then you did not tap the
key early enough, go back to step 1.
Otherwise, you should be seeing a screen like the one pictured below, titled "Advanced Boot Options." It may appear subtly different for older or newer versions of Windows: [caption id="attachment_1399" align="alignnone" width="300"]

Problems accessing the Advanced Boot Options menu
Some common problems when trying to access the Advanced Boot Options menu and their resolutions are mentioned below.
PC starts BIOS setup or shows a boot selection menu
You began tapping the
key too soon, and your BIOS interpreted it as a command to perform a certain action. Shutdown your PC and try again, making sure the BIOS POST has fully-completed before tapping the
Windows boot screen shows up
You did not press the
key in time, and Windows has begun to load normally. Restart your PC and try pressing
a little earlier.
If Windows begins to load normally every time, you might need to press another key on the keyboard at the same time as
. This commonly happens on laptop keyboards that override the F keys unless the
button is simultaneously pressed.
Make sure you're not using a wireless or bluetooth keyboard, as many times it cannot be used to interact with the Windows boot loader (and/or the BIOS). Try again with a wired USB or PS/2 keyboard, following the instructions above.
