One: We in the computer switch has been Non-stop "Del" (some motherboards are pressed F8), and then entered the computer motherboard "BIOS" then we click on "Basic Settings" and then find Floopy move the top after the use of the cursor key set "Disabel" Then press F10 to save the BIOS and boot to see if the problem is resolved, if not down.
Second: We also press the DEL key to enter the BIOS interface at Power-on, and then in the first item will find the "Drivea" item is not "None" then we'll see if we set none if we don't use the UP and DOWN ARROW keys on the keyboard to set it, and then press F10 to save it.
Three: If the above method can not solve the problem is that we have to set a specific four steps:
1, the BIOS set the soft zone or optical optical drive but in the actual soft and hard without these things will also boot F1
2, the BIOS set up a dual hard drive, but your computer dual without dual hard drive This will also boot prompt F1
3, the motherboard battery does not have electricity also can cause the data to lose thereby to appear this fault.
4, the BIOS set up a soft drive This is a long time ago, now there is no so there will be this problem.
