Boot device not found, insert a boot disk and press any key


The "no bootable devices found" error can create headaches, as well as occasional heartache if you're a laptop user. This error appears when your computer is unable to find a device or file required for normal operation. It could indicate one of three issues: hard drive failure, software error or motherboard malfunction. Any of these potential problems can render your laptop useless. Hard drive failure or software errors can lead to data loss, which can cause anguish and catastrophe, depending on the files business information, family photos, student projects at risk.
Hard Drive Failure
The interior of a hard drive is akin to a turntable. Most hard drives contain two to three discs, known as platters, which are similar to records. These platters are read and written on by a tiny needle called the read/write head, similar to the arm and needle on a turntable. When a hard drive functions properly, the platters spin and the read/write head accesses the files necessary to boot your computer. Improper function of any of these physical pieces can cause a mechanical failure and result in the "no bootable devices" error. Software Error
In rare instances, a software problem more specifically, a particularly nasty virus may cause the "no bootable devices" error.
Most often, if a virus attacks and corrupts your system, your computer can still detect the hard drive and operating system, and you'll see some attempt at a normal boot.
If a virus attacks certain system and startup files, however, they may not be detectable next time you boot your computer, thus causing you to see "no bootable devices."
This may also happen if you are manually deleting files from your computer and accidentally delete system files.
Motherboard
Sometimes individual components of your laptop's motherboard malfunction, which can cause problems ranging from loss of wireless capabilities to inability to detect an external power source.
If the components that detect your hard drive fail, your laptop is unable to receive signals from the hard drive and therefore may display the "no bootable devices" error.
Repair
Fixing a "no bootable devices" error can prove costly.
If motherboard failure caused the error, you're probably better off purchasing a new laptop; unless it's under warranty; the average motherboard replacement costs $250 to $500.
You can reinstall your operating system to resolve software errors, which is fairly inexpensive by computer repair standards, costing $80 to $130 dollars, but this step may also overwrite your existing data.
In some cases, data may prove so badly corrupted it's not salvageable.
If you can recover it, however, that raises your repair costs. additional fee.
If hard drive failure caused your "no bootable devices" error, you can replace the drive.
If you need to recover data from a malfunctioning hard drive, send it to a clean room for recovery.
In a clean room, technicians disassemble your hard drive and image each platter; this kind of data recovery is extremely expensive, costing up to $2000 depending on the work involved.
Prevention
There is no way to guarantee you will never receive a "no bootable devices" error, but there are some steps you can take to help prevent it from happening.
Keep your laptop on a flat surface when using it, and avoid any bumps that may cause the hard drive's read/write mechanism to lock up.
Avoid transporting your laptop while the hard drive is active; turn your computer off while traveling.
Additionally, regularly run an anti-malware program to catch and remove viruses or spyware before they cause system problems.

Sensapi.dll error


How to Fix Sensapi.dll ErrorsImportant: Do not download sensapi.dll from a "DLL download" website. There are many reasons why downloading a DLL file is a bad idea. If you need a copy of sensapi.dll, it's best to obtain it from its original, legitimate source.

Note: Start Windows in Safe Mode to complete any of the following steps if you're unable to access Windows normally due to the sensapi.dll error.

  1. Restore sensapi.dll from the Recycle Bin. The easiest possible cause of a "missing" sensapi.dll file is that you've mistakenly deleted it.

    If you suspect that you've accidentally deleted sensapi.dll but you've already emptied the Recycle Bin, you may be able to recover sensapi.dll with a free file recovery program.

    Important: Recovering a deleted copy of sensapi.dll with a file recovery program is a smart idea only if you're confident you've deleted the file yourself and that it was working properly before you did that.

  2. Run a virus/malware scan of your entire system. Some sensapi.dll errors could be related to a virus or other malware infection on your computer that has damaged the DLL file. It's even possible that the sensapi.dll error you're seeing is related to a hostile program that's masquerading as the file.

  3. Use System Restore to undo recent system changes. If you suspect that the sensapi.dll error was caused by a change made to an important file or configuration, a System Restore could solve the problem.

  4. Reinstall the program that uses the sensapi.dll file. If the sensapi.dll DLL error occurs when you use a particular program, reinstalling the program should replace the file.

    Important: Try your best to complete this step. Reinstalling the program that provides the sensapi.dll file, if possible, is a likely solution to this DLL error.

  5. Update the drivers for hardware devices that might be related to sensapi.dll. If, for example, you're receiving a "The file sensapi.dll is missing" error when you play a 3D video game, try updating the drivers for your video card.

    Note: The sensapi.dll file may or may not be related to video cards - this was just an example. The key here is to pay very close attention to the context of the error and troubleshoot accordingly.

  6. Roll back a driver to a previously installed version if sensapi.dll errors began after updating a particular hardware device's driver.

  7. Run the sfc /scannow System File Checker command to replace a missing or corrupt copy of the sensapi.dll file. If this DLL file is provided my Microsoft, the System File Checker tool should restore it.

  8. Install any available Windows updates. Many service packs and other patches replace or update some of the hundreds of Microsoft distributed DLL files on your computer. The sensapi.dll file could be included in one of those updates.

  9. Test your memory and then test your hard drive. I've left the majority of hardware troubleshooting to the last step, but your computer's memory and hard drive are easy to test and are the most likely components that might cause sensapi.dll errors as they fail.

    If the hardware fails any of your tests, replace the memory or replace the hard drive as soon as possible.

  10. Repair your installation of Windows. If the individual sensapi.dll file troubleshooting advice above is unsuccessful, performing a startup repair or repair installation should restore all Windows DLL files to their working versions.

  11. Use a free registry cleaner to repair sensapi.dll related issues in the registry. A free registry cleaner program may be able to help by removing invalid sensapi.dll registry entries that might be causing the DLL error.

    Important: I rarely recommend the use of registry cleaners. I've included the option here as a "last resort" attempt before the destructive step coming up next.

  12. Perform a clean installation of Windows. A clean install of Windows will erase everything from the hard drive and install a fresh copy of Windows. If none of the steps above correct the sensapi.dll error, this should be your next course of action.

    Important: All the information on your hard drive will be erased during a clean install. Make sure you've made the best attempt possible to fix the sensapi.dll error using a troubleshooting step prior to this one.

  13. Troubleshoot for a hardware problem if any sensapi.dll errors persist. After a clean install of Windows, your DLL problem can only be hardware related.

Applies To

The sensapi.dll error message could apply to any program or system that might utilize the file on any of Microsoft's operating systems including Windows 7, Windows Vista, Windows XP, and Windows 2000.

How do I access the hidden partition to reinstall operating system?


Turn on or restart your notebook, then press F11 while your notebook is
starting.
3 Insert the Operating System Recovery CD/DVD when prompted. The System
Recovery program starts.
Click a system recovery option
Full System Restore (Destructive) reformats the hard drive and
restores the system software as it was when you purchased your
notebook. This process deletes your data files.
Full System Restore with Backup (recommended) moves the
contents of the hard drive to the C:\My Backup folder and installs
a new copy of Windows XP. This option saves your existing data
files, but all programs must be reinstalled and the program settings
reconfigured. You need at least 4 GB of hard drive space to use this
restore option.
5 Click Next. The System Restore - Format and Recover dialog box opens.
6 Click Yes. Files are restored to your hard drive. When file recovery has
finished, the System Restore dialog box opens.
7 Click Restart. Your notebook restarts, and Windows finishes its setup and
installation.
Important
After you restore your system, it will
appear with the same files and programs
it had when it shipped from the factory.
You still need to download Windows
updates and antivirus updates to bring
your notebook’s software up to date.
8 Reconnect your Internet cable and all USB peripheral devices. You are
done.

Dell Laptop Inspiron 6400 - "Stop Error Screen" appearing


This stop error means that your ntfs file system is corrupt (damage in the file system, bad hard drive data, corrupt SCSI or IDE drivers or a corrupt ntfs.sys file).

There are two ways,you might be able to fix it

1, If you still can access Windows, try to disable any backup programs, virus scanning programs or disk defragmenter tools. Try also to run a hardware diagnostics tool to detect any errors your hard drive might have. And run chkdsk /r to detect and repair any file system structural damage.

2, If you are unable to load Windows. Then you should try to access your ntfs partitions by making a ntfs boot disk with NTFS4DOS (freeware).

After you load the bootable floppy disk onto your damaged system, select either option one (1) or option three (3). If you selected option one (1), type chkdsk /r at the command prompt, and your problem should go away after the disk has been repaired.

Note! Unfortunately there is a chance that your partition is corrupt beyond repair and all of your data is lost. In that case, you need to reformat the partition to be able to use it again.

What the computer is trying to tell you is that the hard drive has gone faulty somehow... hard Drives can and do spontaneously fail all the time.. It probably shut down because it detected a serious fault with the hard drive. I think that at least you are going to have to try a new hard drive to see...
