My cd rom wont boot up at start up

it's not locksum ,its Check SUM or CRC errors.
what OP, are you running,? windows what. i guess.

the CMOS battery just died.
install a new one.
all puters this old do that, the battery is good for 7-10 years,
and all fail.
DO NOT FLASH your BIOS, fix the real problem first

when the battery dies, all our bios setting were lost
including boot device, and order
fix battery
then go into BIOS and put back boot order.

Insert a blank diskette into the floppy drive. Click start click on computer you should see all of you drives.

Right-click on Drive A. You will see the option to format the drive.

Click on Format. Depending on your operating system, you will see an option that reads either "Create a system disk" or "Create a MS Dos system disk." Click the box next to this option.

Click the "Start" button to begin formatting the disk.
When completed, you will have a bootable floppy disk.

For CD Rom or DVD disks

Open the software that you use to burn or write files to the CD-rom or DVD drive.

Click on "Make a Data CD or DVD." Insert a blank CD-R or DVD-R disk into the drive.

Look for the option to "Make this disk bootable." You may have to scroll over the various icons displayed to find this option. Click on the option.

Burn the CD or DVD as usual. Once completed, this disk can be used to boot your computer.

hope this helps

Causes

4. Misconfiguration with the boot.ini file.
5. Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
6. New hard disk drive being added.
7. Corrupt boot sector / master boot record.
8. Seriously corrupted version of Windows 2000 or Windows XP.
9. Loose or Faulty IDE/EIDE hard disk drive cable.
10. Failing to enable USB keyboard support in the BIOS.

Solutions

Computer is booting from a non-bootable source

Many times this error is caused when the computer is attempting to boot from a non-bootable floppy disk or CD-ROM. First verify that no floppy diskette or CD is in the computer, unless you are attempting to boot from a diskette.

Note: This error has also been known to occur when a memory stick is in a card reader and the computer is attempting to boot from it. If you have any card reader or flash reader make sure that no memory stick is inside the computer. Additionally disconnect all USB drives, cameras, ipods, iphones, etc. from the computer.

If you are attempting to boot from a floppy diskette and are receiving this error message it is likely that the diskette does not have all the necessary files or is corrupt.

If you are attempting to install Windows XP or Windows 2000 and are receiving this error message as the computer is booting verify that your computer BIOS has the proper boot settings. For example, if you are attempting to run the install from the CD-ROM make sure the CD-ROM is the first boot device, and not the hard disk drive.

Second, when the computer is booting you should receive the below prompt.

Press any key to boot from the CD

Important: When you see this message press any key such as the Enter key immediately, otherwise it will try booting from the hard drive and likely get the NTLDR error again.

Note: If you are not receiving the above message and your BIOS boot options are set properly it's also possible that your CD-ROM drive may not be booting from the CD-ROM properly. Verify the jumpers are set properly on the CD-ROM drive.

• Verifying the CD-ROM cables are correctly connected.

Computer hard disk drive is not properly setup in BIOS

Verify that your computer hard disk drive is properly setup in the CMOS setup. Improper settings can cause this error.

Corrupt NTLDR or NTDETECT.COM file

Windows 2000 users
Windows XP users

Use an external CD rom or sometimes there is a petition file in the Hard drive to format.

If its the full windows xp cd by booting it from the cd drive it will erase everything and ask if you want to upgrade or advanced install I think. Your correct in choosing the atapi cd-rom as 1st boot device. The cd should be in the drive on startup. IDE is the type of hard disk drive. I'm guessing the FDD stands for floppy disk drive which you might not have that many but you have that many bay windows available.

Put disk in, shut down computer, Start computer and it should give you the xp disk contents. Be aware of data loss though.

This issue may occur if your start device (such as a floppy disk drive, hard disk drive, or CD-ROM drive) does not contain boot files.

To resolve this issue, use one or more of the following methods, and then restart your computer:

• Remove the non-system disk from your boot device. For example, remove the non-system disk from the floppy drive or the CD-ROM drive.
• Change your computer's boot sequence. To do this, you must change your computer's setup and the option that controls which device your computer uses to start from. Make sure that you select a device that has boot files (or operating system files) installed.
• If you start your computer from a hard disk drive, install a bootable operating system (such as Windows XP) on the drive.

hi im josh in cebu phils.may i help you? friend try to do this things. first i suggest to change new ide or sata cable.if still persist.try the following:
Boot order: Traditionally, a computer is set to boot first from the floppy drive, and then from the main hard drive (Drive C). This means that the computer will check the floppy drive first for boot files. If there is no disk in the floppy drive, the computer will then go to the hard drive to look for boot files. That is why if you leave a non-bootable floppy disk in the drive and try to boot up, you'll get an error message such as "NTLDR is missing. Press any key to restart." or "Non-system disk or disk error." This can be changed to pretty much any order, including CD and DVD drives. It is useful when installing Windows on a new or just-formatted computer to set the computer to boot first from a CD-ROM drive, and then insert the Windows installation CD-ROM into that drive. This saves you from having to use boot floppies that might or might not come with the Windows CD-ROM. Good luck.

1.If you purchase an external USB CD drive you will not need to use your floppy discs for booting. 2. You can connect a USB CD drive to your system. 3. Your system will recognize any device plugged into your USB drive. 4. There is no CD drive available for internal installation in your computer. 5. With the USB CD drive plugged in and the windows installation disc inserted, your computer should take you through the setup program automatically.

You need to use floppy disks (called boot disks) to boot DOS with cd-rom drivers, because the win98 cd isn't bootable by default.

I suggest you to go to http://www.bootdisk.com/bootdisk.htm and grab the respective windows 98 boot disk.

You will need a functional computer to write the disk image into the floppy.

After that put the boot order in BIOS as floppy first.

Once you see DOS prompt A:\> just access your cd-rom drive like d: or e: and then type install
