After installing Win8 system, how can I enter the BIOS?

Some friends just bought a brand notebook, pre-installed is the win8 home version of the operating system, want to insert the boot U disk to replace the win7 system, but found that no matter which shortcut button can not be booted from the U disk, can not enter the Bios, this What is the reason? How to solve win8 can not enter the BIOS?

There are generally two reasons, I suggest you take steps to solve the problem:

First, I suggest you first update the BIOS in the Windows environment, after the update is restarted, see if you can enter the system, if still If it is not possible, it is very likely that the notebook's BIOS battery is dead. Your book is old, and this possibility is very high. It is recommended that you replace the BIOS battery directly.

The battery of the notebook BIOS is generally near the power battery, but there is a notebook that is not like this. You need to open the bottom to check the position. The blue color is the battery. Desktop batteries are easier to spot.

Second, if the replacement BIOS battery is no way to enter the BIOS system settings that problem, most likely opened the quick start, it is similar to high-level sleep mode, off by default , and then boot is actually a "hot start" process, you do not need to reload the hardware information, so you can not enter the BIOS. Close it.

First click on the battery icon, select “More Power Options", then click “Select Power Buttons>, then click on “Change Current Unavailable Settings”.

will now be under the & ldquo; to enable quick start & rdquo; to remove the hook before in this column, then save your changes, you can restart the machine.
