I have a Toshiba Satellite C660D and i hear a sound like tick tack and it says to me on the black screen:Intel UNDI, PXE-2.1 (build 083) Copyright (C) 1997-2000 Intel Corporation This Product is covered by one or more of the following patents: US5,307,459, US5,434,872, US5,732,094, US6,570,884, US 6,115,776 and US6,327,625 Realtek PCIe FE Family Controller Series v1.19 (08/10/09)

SOURCE: Hi there, I have a Toshiba

probably doing a network boot instead of booting from the harddrive. enter the BIOS make sure the harddrive is detected.Also check the boot configuration and verify if the harddrive is set as the primary or default boot.

SOURCE: When I turn on my laptop it goes to a black

based the message that you encounter, it may pertain to boot priority or to BIOS configuration.

My recommendation is for you to access and reset the BIOS settings on your computer.

As soon as you power on your PC, start pressing the F2 key. This should bring up the BIOS (Basic Input Output Systems) screen. Make sure your Hard Drive is listed in the Boot order. Usually a CD drive is listed first, then the Hard Drive as a second boot device. If you do not see the Hard Drive listed, then it probably is bad and needs replacing. If it is listed correctly in the boot order, your Operating System has crashed, and you will need the recovery disks or the instalation disk for your Operating System (XP, Win7,etc.)
