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

You may crack the password and login your computer again.

Windows Password Recovery is right what you need in your case. The password recovery tool is designed to reset Windows login password once you accidentally forgot it or have no access to your system including Windows 7, Vista, XP etc. By burning a bootable CD, you can enter almost any computer with Windows administrator login password protected within a few seconds. Here are the step by step tutorial, pretty easy, I am sure you can handle it!

Step 1: Download Windows Password Recovery and install it on another computer.
Step 2: Prepare a blank CD/USB and run the software and use it to burn the ISO file to it.
Step 3: Put it into the CD-ROm and restart your locked computer. Change the BIOS setting of your locked computer to make it boot from the CD-ROM or USB drive. Note: start computer and press F2 or Delete to enter BISO setup
Step 4: Boot your locked computer from the created disk and remove your forgotten password. GOOD LUCK!

It may have lost the drivers to read the disk.

When you try to write data to an optical disc, you may experience any of the following symptoms:

* You receive various disc write error messages.
* You experience issues with the drive and the built-in recording feature of Windows XP.
* You experience issues with third-party programs that you use to write data to the disc.
* You cannot read the disc in all versions of Windows.

TROUBLESHOOTING

Troubleshooting specific errors
If you experience one of the following errors, follow the appropriate steps to resolve the error.

* There is no disc in the drive. Please insert a writable CD into drive.
This error can occur if the CD-R drive or CD-RW drive is not recognized as a recordable device. This error can also occur if the device driver has been corrupted. To resolve this issue, see Method 3 in the "General troubleshooting" section and Method 1 in the "Advanced troubleshooting" section.

* Drive not accessible, incorrect function
This error message typically occurs when you try to write to a CD-R or a CD-RW, and the Windows XP built-in disc recording feature does not recognize the CD drive as a recordable drive. This error message may also occur if specific third-party programs are installed. For more information about how to troubleshoot this error,

when you access the CD-ROM drive, the DVD-ROM drive, or the CD-RW drive
* Error Deleting File or Folder.
Cannot delete file name. Files on this CD-ROM drive are read-only. You cannot copy or move files over to this CD-ROM drive.

This error message can occur because individual files cannot be deleted from the CD-RW. You cannot use the CD disc recording feature of Windows XP for random-access storage while you are writing to disc.

To set the service to Automatic, follow these steps:
1. Click Start, click Run, type services.msc /s, and then click OK.
2. Double-click IMAPI CD-Burning COM Service.
3. Under Service Status, click Start.
4. Try to write data to a CD.

Hi,
Sounds like you're trying to flash the bios..

Using ASUS EZ Flash to update the BIOS: The ASUS EZ Flash feature allows you to easily update the BIOS without having to go through the long process of booting from a diskette and using a DOS-based utility. The EZ Flash is built-in the BIOS firmware so it is accessible by simply pressing <Alt + F2> during the Power-On Self Tests (POST). To update the BIOS using ASUS EZ Flash: 1. Visit the ASUS website (www.asus.com) to download the latest BIOS file for your motherboard and rename the downloaded file as P4P800SE.ROM. Save the BIOS file to a floppy disk. 2. Reboot the system. 3. To launch EZ Flash, press <Alt+F2> during POST

Hope this helps

I was able to find drivers for this device which turns out to be an SD Card reader built into the laptop. Here is the site I found it on: http://www.toshiba.com/tai/support/support_cons.jsp
You'll want to click on "Computers and Accessories" on the left hand side, and then select "Laptop Computers".
Upon selecting the correct model, I found all the pertinent drivers for my laptop.
The Category, which is the middle column on the drivers page, is going to be something along the lines of "Driver Flash Memory SD"
Good Luck!

Assuming you are using a Cruzer Micro Drive with U3 Smart, things can be a little confusing because the drive actually shows up as two independent devices. When you insert the drive, there should be two devices showing up in your list of drives. One of them is installed as a CD Rom Drive and the other one is a Removable Drive. If you double click on the CD Rom Drive instead of the Removable Drive and you don't have any U3 applications mapped to the CD Rom Drive, then you'll get an insert disk message because Windows thinks that the CD Rom Drive is empty. Just use the Removable Drive if you want to simply install and transfer files.

Find a technician who can do it for you - or if you are conversant with computers you get an eternal dvd rom Drive and use it. Have you tried the floppy drive if your computer has any? or the flash disk?

please try one these options.
