    define "nothing happened" Did you run the CD? did it start up? did it load?

    Lets put the CD on hold for the while and try a different approach. Are you able to take the Hard Drive (HDD) from your non working Toshiba and plug it into your other working computer. (I am assuming that they are both desktops?)

    Just out of curiosity, is your Toshiba a "satellite" series? And important questions how many ram slots do you have on that laptop?

    just a shot in the dark but try removing one ram stick and boot the PC. If nothing happened try putting in the second stick in the same slot and try booting PC. Do the same thing for the second slot. (I mean boot one stick at a time for each slot, if you have only one stick put it in the other slot)

    Also confirm this. You have said that you are unable to get to bios? You have mentioned that you see Toshiba logo on the start up. Do you see something like "F1 for setup"?

    i will try your ram suggestion,

    and usually i hold the esc key .....

    (and while the toshiba logo is on and press f1 for setup appears)

    but now it does not

    F1 should get you to bios. When you are in there, make a CD drive a primary boot device followed by hard drive as a secondary boot device and disable the rest...

    thats the thing, i cant get into it.it wont let me,

    i hold the esc key and the f1 message does not appear

    Forget the ESC key, just press F1 every second during the boot. But first do the RAM thing...
    Your PC does not beep anytime during the boot, right?

    damn,...
    from what you have told me (or us) and from what I know from my previous experiences I would really like to get the hard drive diagnosed (which we can not do because you have no way of doing it) and since we can not get to bios and set the CD-drive as a primary boot device we can not use diagnostic CD either. That really limits the available options. I would really appreciate if someone else from TS would pitch in with another point of view and/or idea.

    All I can think of now is to do a random things, which have slim chance of working. First one is to remove the HDD and boot the PC and see what happens. It should tell you "No OS found" If it does not we may have been barking up the wrong tree, if it does restart the PC and try to get to bios again with HDD unplugged...

    Be careful when removing the HDD do not move or shake it a lot...

    i emoved the hdd

    it turned on and said IDE #0 error

    then it showed the toshiba logo

    and then the black screen with the blinking underscore

    out of curiousity i press ctrl and alt and delete and it went back to the toshiba logo

    but this time after the toshiba logo it said

    Intel (R) Boot Agent FE v4 1.10

    Pxe-E61: Media test failure

    well, I have check up on those errors that you have gotten. There is a good chance they show up because the HDD is out of the Laptop.

    So, did you get to bios while the HDD was out?

    Also make sure that nothing is connected to your laptop via any ports, such as, external HDD, printer, scanner, camera, network cable,... All that you should have connected is power cord and that is it.

    How do you connect to interned with the Toshiba laptop? wired or wireless. If wireless do you have internal or external card?

    i still could not connect to bios

    and there is nothing connected to the pc.

    and..... i used a wired connection, no card in this baby.

    OK well put the Hard Drive back again (make sure it makes a proper connection)

    Turn on the laptop again, and lets try to get back into Bios Setup
    Press F1 key repetitively just as you turn on the laptop
    This should get you into Bios Setup (if not you have a keyboard fault!)

    Once in Setup, locate the boot sequence and confirm set to CDRom first
    Save and Exit

    Boot from CD (hopefully this is burnt properly as a boot CD)

    Well I just read the manual and it said F1

    Lets just try all of them ;)

    When the computer turns on from a cold start (ie not Restart) Press:

    F1 F2 F10 Del Esc keys

    It's bound to be one :D

    welcome back kimsland, and yes we need to get to BIOS.
    I wonder if F8 works. IT is not BIOS access related, but I am curious.

    If it is a keyboard problem, try connecting external keyboard via USB, or PS2 if you have it, and use those F# keys

    i tried all of them and nothing.

    but when it goes to the black screen with the blinking underscore,

    but if i press ctrl alt delete it goes back to the toshiba logo and then goes back directly to the black screen with the blinking underscore

    Because this thread is so large I can't remember if you had data on your Hard DRive or not :confused:

    Basically I'm thinking remove the partition
    But you may need an adapter to plug it in a Desktop computer

    we already explored plugging in the HDD to the desktop
