I am getting a disk 1/0 error and am not confident at all with computers. How can I fix this so my son can use the computer? My PC is about 6 years old and I only ever used it 9-10 times


A..Access the BIOS setup by pressing the key designated for your BIOS at Startup? It can be Del/F1/F2 or whatever and will be shown on Boot Screen before Windows is loaded.
B. Do you have a Win98 Boot Diskette proven to work well in a PC?
If so:
1.With the Win98 Boot Diskette in the Floppy Drive, Restart the PC.
2. Press the BIOS key [Eg:Del] enter BIOS setup
Check for correct YYYY/MM/DD and Time for your Time Zone and proceed to take a good look at the entries of your IDE devices and Floppy Drive with special attention to your Hard Drive(s) in IDE section. If they are all properly identified and normal, you can EXIT the BIOS. [ It does not mattere "Save changes" or "don't save changes" as you have not made any changes.]
3. Wait for Boot Disk to be accessed and Windows Startup Menu to appear with the Options:
1.Start Computer with CD-ROM support.
2.Start Computer without CD-ROM support
3. Help File
4. Select the option,1.Start Computer with CD-ROM support. and ENTER
5. Watch the screen for CD-ROM driver installed successfully" and "Diagnostic Tools " installed and CD-ROM drive letter designation and finally appearance of A:\Prompt
6. At, A:\ Prompt type FDISK and press ENTER.
7. Accespt Y at the bottom of "Large Disk Support" message.
8. At FDISK menu select #4. Display...."
9. Check if the HDD is shown as C: A FAT32 and size.
I am suspecting a problem somewhere here; so if you don't have an Active C: drive press ESC >ESC and remove boot Disk CTRL +ALT+ DELETE to reboot and post back
If you have an Active C: drive, press ESC >ESC to A:\Prompt and type in C: and then at C:\> prompt, type DIR and [ENTER] look for Windows Directories. Here is another Problem area. If you cannot Find any Dir or get an Error, make sure your typing and spacing are OK [ No space after Drive letter for the Command] and if so, ALT+CTRL+DEL or Power Off.

If the problem is same do next .

Alternative Start Mode

1. Re-boot PC, as it starts tap F8 several times until the windows boot window appears.
2. Scroll to "Start with last known good configuration.)
3. Press "Enter"

1. Re-boot PC, as it starts tap F8 several times until the windows boot window appears.
2. Scroll to "Safe Mode" (With networking, if you want to access the internet)
3. Press "Enter"

System Restore

1. Go "Start"
2. "All programs"
3. "Accessories"
4. "System tools"
5. "System Restore"
6. ensure "Restore to an earlier time" is checked and click "Next"
7. Select an earlier date when your PC worked well. (Must be a highlighted date)
8. Click "Next"
9. Allow system restore and reboot

NTLDR is Missing.

Related errors:

Below are the full error messages that may be seen when the computer is booting.

NTLDR is Missing
Press any key to restart

Boot: Couldn't find NTLDR
Please insert another disk

NTLDR is missing
Press Ctrl Alt Del to Restart
Computer is booting from a non-bootable source.
Computer hard disk drive is not properly setup in BIOS.
Corrupt NTLDR and/or NTDETECT.COM file.
Misconfiguration with the boot.ini file.
Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32.
New hard disk drive being added.
Corrupt boot sector / master boot record.
Seriously corrupted version of Windows 2000 or Windows XP.

Computer is booting from a non-bootable source

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.

Computer hard disk drive is not properly setup in BIOS

Verify that your computer hard disk drive is properly setup in the BIOS / CMOS setup. Improper settings can cause this error. Additional information on how to enter the BIOS / CMOS setup can be found in document CH000192.

Corrupt NTLDR and/or NTDETECT.COM file

Windows 2000 users
Windows XP users

Windows 2000 users

If your computer is using Microsoft Windows 2000 and you are encountering the NTLDR error. Create the below boot.ini file on the floppy diskette drive.

[boot loader]
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINNT="Microsoft Windows 2000 Professional" /fastdetect

Copy the NTLDR and NTDETECT.COM files from another computer using the same operating system. Both of these files are located in the root directory of the primary hard disk drive. For example, C:\NTLDR and C:\NTDETECT.COM should be the locations of these files on many computers.

Please keep in mind that these files are hidden system files, if you need additional help with viewing hidden files in Windows please see document CH000516.

Once these files have been copied to a floppy diskette reboot the computer and copy the NTLDR and NTDETECT.COM files to the root directory of the primary hard disk drive. Below is an example of what commonly should be performed from the A:\> drive.

copy ntldr c:
copy c:

After the above two files have been copied, remove the floppy diskette and reboot the computer.

Windows XP users
Insert the Windows XP bootable CD into the computer.
When prompted to press any key to boot from the CD, press any key.
Once in the Windows XP setup menu press the "R" key to repair Windows.
Log into your Windows installation by pressing the "1" key and pressing enter.
You will then be prompted for your administrator password, enter that password.
Copy the below two files to the root directory of the primary hard disk. In the below example we are copying these files from the CD-ROM drive letter, which in this case is "e." This letter may be different on your computer.

copy e:\i386\ntldr c:\
copy e:\i386\ c:\

Once both of these files have been successfully copied, remove the CD from the computer and reboot.

Misconfiguration with the boot.ini file

Edit the boot.ini on the root directory of the hard disk drive and verify that it is pointing to the correct location of your Windows operating system and that the partitions are properly defined. Additional information about the boot.ini can be found on document CH000492.

Attempting to upgrade from a Windows 95, 98, or ME computer that is using FAT32

If you are getting this error message while you are attempting to upgrade to Windows 2000 or Windows XP from Windows 95, Windows 98, or Windows ME running FAT32 please try the below recommendations.
Boot the computer with a Windows 95, Windows 98 or Windows ME bootable diskette.
At the A:\> prompt type:

sys c:

After pressing enter you should receive the "System Transferred" message. Once this has been completed remove the floppy diskette and reboot the computer.

New hard disk drive being added

If you are attempting to add a new hard disk drive to the computer make sure that drive is a blank drive. Adding a new hard disk drive to a computer that already has Windows installed on it may cause the NTLDR error to occur.

If you are unsure if the new drive is blank or not try booting from a bootable diskette and format the new hard disk drive.

Corrupt boot sector / master boot record

It's possible your computer's hard disk drive may have a corrupt boot sector and/or master boot record. These can be repaired through the Microsoft Windows Recovery console by running the fixboot and fixmbr commands.

Additional information and help in getting into the Microsoft Windows Recovery console can be found on document CH000627.

Seriously corrupted version of Windows 2000 or Windows XP

If you have tried each of the above recommendations that apply to your situation and you continue to experience this issue it is possible you may have a seriously corrupted version of Microsoft Windows. Therefore we would recommend you reinstall Microsoft Windows 2000 and Windows XP.

If you are encountering this issue during your setup you may wish to completely erase your computer hard disk drive and all of its existing data and then install Microsoft Windows 2000 / Windows XP. Additional information about erasing the computer and starting over can be found on document CH000186.

Loose or Faulty IDE/EIDE hard disk drive cable

This issue has been known to be caused by a loose or fault IDE/EIDE cable. If the above recommendation does not resolve your issue and your computer hard disk drive is using an IDE or EIDE interface. Verify the computer hard disk drive cable is firmly connected by disconnected and reconnecting the cable.

If the issue continues it is also a possibility that the computer has a faulty cable, try replacing the hard disk drive cable with another cable and/or a new cable.

Hope this helps ,

NTLDR is missing Press Ctrl Alt Del to restart

The operating system got whacked. You can recover by booting from the installation CD and choosing "R" for recover, then following instructions - if, that is, the real cause isn't a dying hard disk.

I'd download first thing the UBCD utility, boot from it, and run a hard disk diagnostic with SMART reporting. If it says that the HD is healthy, go for recover. If it says it is NOT healthy, remaining in UBCD, try accessing the disk and backup all data you care for, as quickly as you can, on an external USB device of suitable size, THEN attempt recovery.

Re-install the proper windows operating system. I know that sounds like a blanket solution, but it's imperative that you use the proper type of operating system.

Seems some operating system file either deleted or missing in your laptop. Change the boot media HDD to CD/DVD ROM in BIOS. Reformat your PC. I think it will work.

When you first turn on your computer keep pressing F8 to bring up the startup menu. Choose the option that says "safe mode". If you can get into safe mode, then try to do a system restore back to the last date you have available and then reboot and you should be okay.

If you can't get into safe mode and you get the same error message then you have corrupt system files and you'll need to wipe out the drive and start over.
