    Ok. I will list every detail of the problem and of my trials to solve it so that you could have as clear an idea as possible. Thanks in advance. I HAVE BEEN WORKING ON THIS PROBLEM FOR HOURS SO IT WOULD BE GREAAAAAAATLY APPRECIATED if anybody could help me out!

    1.
    I was trying to install Ubuntu, so need to boot from CD ( i know i can do that directly in windows using wubi, but that's not what I want to do. I am just trying to boot from CD and install Ubuntu on an allocation of memory i had set free for it.). I set the boot sequence to be 1.CD-ROM 2.Hard-disk 3.Removable. However, even under this settings my computer still directly goes to Windows. *:I do notice the CD-drive working at the beginning of the start-up, but then Windows comes out eventually *
    2.
    So I figured the problem might be the system did try to boot from CD but failed, so it then boots from harddisk and found Windows. Therefore I went into BIOS and set all 3 booting devices to be CD-ROM, then restarted. Now I have this error message : disk boot failure, insert system disk and press enter.

    3.
    The CD is good, because i tried to boot my laptop from it and it works well.

    4.
    I tried to upgrade my BIOS but couldn't because the system showed the same message when i tried to boot from the BIOS flash disk.

    5. I built this desktop from scratch up, and when I first tried to install an OS to it, I used a CD and it booted well.. which is about 6 months ago. I never tried to boot it from CD since then. I installed windows 7 RC at that time, and all I have done since then is to install a windows 7 RTM. I did that in the previous windows OS, so didn't boot from CD again.

    6. The CD drive is good, it works perfectly in windows 7.


    That's all i have for now.. could anybody help me plz!!

    After reading through step 4 above, I don't need to go further.

    Some optical drives fail in such a way as to work fine reading a disk in Windows but will not boot from a bootable disk. Replace the optical drive with a known-good one you may have access to and see what happens.
