Check device manager and see if its showing a conflict.If so you will need to click Start -> Run, type Regedit

1. Remove the Upperfilters and Lowerfilters values completely from the following registry key (Windows 2k/XP):
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}
2. Restart your computer.
This worked for me and CD's work again.

Ntldr is missing press ctlr+alt+ and delete to restar and i did and don't workz


First I have to assume that you are running Windows XP. This solution should work for other versions of Windows.
The "NTLDR is missing" error displays very shortly after the computer is first started, immediately after the Power On Self Test (POST) is complete. Windows XP has only initially begun to load when the NTLDR error message appears.
Causes of NTLDR Errors
There are a number of possible causes for NTLDR errors, including the most common "NTLDR is missing" error message.
The most common reason for this error is when your PC is trying to boot from a hard drive or flash drive that is not properly configured to be booted from; in other words, it's trying to boot from a non-bootable source. This also would apply to media on an optical drive or floppy drive that you're trying to boot from.
Other possible causes include corrupt and misconfigured files, hard drive and operating system upgrade issues, corrupt hard drive sectors, an outdated BIOS, and damaged or loose IDE cables.
How to Fix NTLDR Errors
1.Restart the PC. The NTLDR error could be a fluke.

2.Check your floppy and optical (CD/DVD/BD) drives for media and disconnect any external drives. Often times, the "NTLDR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk, CD/DVD/BD, or external hard drive or flash drive.
Note: If you find that this is the cause of your problem and it's happening a lot, you might want to consider changing the boot order in BIOS so the hard drive with Windows installed is listed first.

3.Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including NTLDR errors.
Note: There is usually an Auto setting for hard drive and optical drive configurations in BIOS which is usually a safe bet if you're not sure what to do.

4. Restore the NTLDR and ntdetect.com files from the Windows XP CD. Restoring these two important system files from the original Windows XP CD may do the trick.

5. Repair or replace the boot.ini file. This will prevent the NTLDR error if the cause of the problem is a boot.ini file that is not configured properly for your Windows XP installation.

6. Write a new partition boot sector to the Windows XP system partition. If the partition boot sector has become corrupt or isn't properly configured, you may receive the "NTLDR is Missing" error.

7. Repair the Windows XP master boot record. NTLDR error messages may also appear if the master boot record is corrupt.

8. Reseat all internal data and power cables. NTLDR error messages could be caused by loose or malfunctioning IDE cables.
Try replacing the IDE cable cable if you suspect it might be faulty.

9. Update your motherboard's BIOS. Occasionally, an outdated BIOS version can cause the "NTLDR is Missing" error.

10. Perform a repair installation of Windows XP. This type of installation should replace any missing or corrupt files. Continue troubleshooting if this does not resolve the issue.

11. Perform a clean installation of Windows XP. This type of installation will completely remove Windows XP from your PC and install it again from scratch. While this will almost certainly resolve any NTLDR errors, it is a time consuming process due to the fact that all of your data must be backed up and then later restored.
If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows XP.

12. Replace the hard drive and then perform a new installation of Windows XP. If all else has failed, including the clean installation from the last step, you're most likely facing a hardware issue with your hard drive.
NTLDR Errors Apply To
This issue applies to the Windows XP operating system, including Windows XP Professional and Windows XP Home Edition.
Windows 8, Windows 7, and Windows Vista utilize BOOTMGR, not NTLDR.
Still Having NTLDR Issues?
See Get More Help for information about contacting me on social networks or via email, posting on tech support forums, and more. Be sure to let me know what steps, if any, you've already taken to fix the "NTLDR is missing" issue.

You need the install program from Toshiba and should be able to download it from the Toshiba site. The drivers, OS and programs were most likely on the D:\ drive, before it got formatted.

When i install the xp cd in my hcl b23 C2D laptop, the problem shown like this. setup did not find any hard disk installed in your computer\r\nhow to slove?


verify that the hard drive is seen in the system bios. If it is not, disconnect and reconnect the hard drive then try again...the drive must be recognized by the computer for windows to see it. If the hard drive is definitely seen by the system, check to see if the manufacturer of your system offers serial ATA drivers for the system. Load the driver on a floppy disk, boot to windows CD, press f6, load driver, continue with installation.

Windows did not start ,drivers missing


  1. Use the Windows XP startup disks or the Windows XP CD to restart your computer.
  2. When the "Welcome to Setup" screen appears, press R to select the To repair a Windows XP installation using Recovery Console, press R option.
  3. Type the number of the Windows installation that you want to access from the Recovery Console, and then press ENTER.
  4. Type the administrator password when you are prompted, and then press ENTER. If no administrator password exists, just press ENTER.
  5. At the command prompt, type the following commands (press ENTER after each command): cd \windows\system32\drivers

    ren ntfs.sys ntfs.oldNote This step renames the corrupted Ntfs.sys file to Ntfs.old. If the Ntfs.sys file is not found, the file is missing.
  6. At the command prompt, type the following command, and then press ENTER: copy cd:\i386\ntfs.sys drive:\windows\system32\driversWhere cd is the drive letter for the CD-ROM drive that contains the Windows XP CD, and drive is the drive where you installed Windows XP.
  7. Remove the Windows XP CD from your CD-ROM drive, type quit at a command prompt, and then press ENTER to quit the Recovery Console.
  8. Restart the computer

How to fix "BOOTMGR is missing" in Windows xp


hey Mr Milebdavi try these steps
  1. Restart the PC. The BOOTMGR error could be a fluke.

  2. Perform a startup repair of Windows. This type of installation should replace any missing or corrupt files, including BOOTMGR. Continue troubleshooting if this does not resolve the issue.

  3. Check your floppy and optical drives for media. Often times, the "BOOTMGR is Missing" error will appear if your PC is trying to boot to a non-bootable floppy disk or CD/DVD.

    Note: If you find that this is the cause of your issue and it's happening regularly, you might want to consider changing the boot order in BIOS so the hard drive is listed as the first boot device.

  4. Check the hard drive and other drive settings in BIOS and ensure they are correct. The BIOS configuration tells the computer how to use a drive so incorrect settings can cause problems, including BOOTMGR errors.

    Note: There's usually an Auto setting in BIOS for hard disk and optical drive configurations which is usually a safe bet if you're not sure what to do.

  5. Reseat all internal data and power cables. BOOTMGR error messages could be caused by loose or malfunctioning power or controller cables.

    Try replacing the PATA or SATA cable if you suspect it might be faulty.

  6. Update your motherboard's BIOS. An outdated BIOS version can sometimes cause the "BOOTMGR is Missing" error.

  7. Perform a clean installation of Windows. This type of installation will completely remove Windows from your PC and install it again from scratch. While this will almost certainly resolve any BOOTMGR errors, it's a time consuming process due to the fact that all of your data must be backed up and then later restored.

    If you can't gain access to your files to back them up, understand that you will lose them all if you continue with a clean installation of Windows.

Issue in installing OS


OK. Well the error appears because the installation process doesn't recognize your hard drive device. And from the error I suppose it is a SATA HDD. You have two options: 1. Enter Bios, look for hard drive settings and change the mode from AHCI to Compatibility 2. Put the Motherboard CD into the optical device, insert a diskette, boot from the CD and select from the menu the option that is says something like "Sata drivers" or something like this. Restart the computer, insert the Windows XP CD and press F6 when it ask you if you want to install a new hard drive. Select to install the drivers from the diskette and continue the installation as normal
If you need further assistance, just leave a comment.

I cant start my computer because system32\driver\isanpn.sys is missing or corrupt


You need to replace that missing or corrupt system file. If you don't have your disk, you can borrow someone else's Windows XP disk (SP2) because you will need an XP disk to access the recovery console to replace isanpn.sys file.

Here's a link to the full steps on Microsoft's website to go to the recovery console and replace that file:

Install windows XP on toshiba satellite U300


Hello
The windows Xp installation doesent find your hardrive because you have a sata drive. you need to adjust the settings in the bios so the sata drive appears as a ordinary IDE drive(ide native) or something like that. search in the bios settings.
A other way is to burn a new winxp cd with the Toshiba Satellite U300, sata drivers.
download the http://www.softpedia.com/get/System/Back-Up-and-Recovery/Barts-PE-Builder.shtml
and download the toshiba harddrive drivers and creat a new cd.
but the simples way is to make the change in bios.
good luck
