    if it happens that you are prompted by the following error message "DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER", "No system disk", it means that the computer did not find the operating system to start (boot).


    A diskette or CD has remained in the drive

    Check out if any diskettes, CD-ROM or DVD-ROM are present in respective drives, remove them and restart your computer

    The boot sequence is incorrect BIOS

    Enter the BIOS setup of your computer and edit the boot (boot sequence) so that the computer starts primarily on drive C:

    A new hard drive was installed

    In the case that a new hard drive has been installed, this message is quite normal.
    Just insert the correct CD to install the system (usually Windows), then restart, while making sure the CD-ROM is first in the defined in the BIOS setup as first boot sequence.

    The hard drive is unplugged

    Open the system unit and check that power cable of the hard drive is properly connected.

    Corrupted system files

    It may happens that some system files needed to boot the computer have been deleted /damaged or that the boot sector of the disc is damaged.

    To determine this, start the computer with a system disk or CD-ROM installation of Windows (via the Recovery Console), and once started, type Dir C: to check if the contents of drive C: are accessible. If its ok then the problem comes from missing or damaged files, then you just have to run the command:
    fdisk /mbr
    sys c:

    Note that before any restoration of the boot sector with the command fdisk / mbr, (supposing that there is a virus), it is recommended to use an antivirus running under DOS, such as

    Damaged disk

    If the hard disk or a partition is damaged:
    If it detected in the BIOS setup, there is a chance that it is
    not out of service.
    If it is, try reinstalling the system through the installation CD, in order to reformat or recover the partition using a utility.
