Question about Acer Extensa 4620 Notebook

Booting Error Message No Operating System Found

This Item is a Acer - Extensa 5420
Once the booting page loading, I am receiving the error message :
PXE-E61: Media Test Failure, Check Cable
PXE-M0F: Exiting PXE ROM
Operating System Not Found.
So I figured there was a issue on the Bios screen, I went in and reset to defaults, saved and exited, same error message. So I booted the system up using Linux LiveCD 8.10 and used without installation, When I clicked on '' Install '' to hopefully, find some partitions there was no partitions found. ** BTW I am currently using Windows Vista on the Notebook. **
So I figured I should try using the Windows Vista Recovery CD that I have downloaded from the site, Once loaded, I attempted to REPAIR YOUR COMPUTER, once I clicked on that, there were not System Recovery Options - No drivers found. So I clicked Next, Started with Start up Repair, from there received error message of ''ROOT CAUSE FOUND: A hard Disk could not be found. If a hard disk is installed, it is no responding.'' So from the common sense, and the obvious, looking at me right in the face, there was : A. No hard drive or B. Hard drive was not responding.
So Like anybody, I took apart the bottom of my notebook, where I found the hard disk, removed it, ensured it was clean. placed back in with care, rebooted the notebook....and what do you know.....same error message. I really need help here, and please, be easy and not too much terminology, I'm a noob to all this. BTW I also attempted to contact Acer Tech Support, and like the obvious, they wanted to me to pay for software, that wont even work. So to answer any possible questions about accessing the web, I can do so, with Linux LiveCD 8.10. thats about it, no flash players can be used unfourtently, I have tried downloading a number of anti-virus programs, but just receive, error msg to error msg, and so on, and so forth. Any Suggestions will be taken with all respect and gratidue.
Thanks In Advance,

    How can I tell if it is detected in the BIO?

    What were you doing when the problem started? Were you reinstalling Vista? Installing another operating system on a computer that originally had Vista? Or was the computer working just fine and then one day you turned it on and got this screen?

Make sure that hard drive is detected in BIOS. If not, there is a problem with the hard drive and any attempt to install OS will be futile since there is no hard drive detected. If this basically means you have a busted hard drive, you may need to replace it then to continue with OS installation.

    Please follow the instructions listed below for recovery attempt: (If all else fails please proceed with the instructions on the bottom of the page since like I've said this could possibly mean that you need to replace your hard drive which could be busted already.) Thanks.

    I want to restore my computer to its original settings without

    recovery CDs.

    Note: If your system is the multilingual version, the operating

    system and language you choose when you first turn on the

    system will be the only option for future recovery operations.

    This recovery process helps you restore the C: drive with the original software

    content that is installed when you purchase your notebook. Follow the steps

    below to rebuild your C: drive. (Your C: drive will be reformatted and all data

    will be erased.) It is important to back up all data files before using this option.

    Before performing a restore operation, please check the BIOS settings.

    1 Check to see if Acer disk-to-disk recovery is enabled or not.

    2 Make sure the D2D Recovery setting in Main is Enabled.

    3 Exit the BIOS utility and save changes. The system will reboot.

    Note: To activate the BIOS utility, press during POST.



    To start the recovery process:

    1 Restart the system.

    2 While the Acer logo is showing, press + at the same time to

    enter the recovery process.

    3 Refer to the onscreen instructions to perform system recovery.

    Important! This feature occupies 10 GB in a hidden partition on

    your hard disk.

The BIOS, which handles the initial start up of your computer, cannot find your hard drive and thus cannot boot your operating system (ie, Windows). Open up your computer and confirm the power cable is firmly connected to the hard drive and that the cable that connects the hard drive to the motherboard is firmly secure. If both of these check out, then try downloading this bootable CD on another computer. This CD, among other things, has a few hard drive utilities that will help further diagnose the problem. Finally, if the utilities on this CD are unable to see the hard drive itself, then is may need to be replaced. Try testing with another hard drive or another cable to connect it to the motherboard.

This error comes up if the computer is not able to detect the hard drive. Power off the computer. Power it back on and tap the number 2 key 4 - 5 times at the Dell logo screen.

The error PXE-E61: Media test failure usually means the hard diskhas failed or the hard disk needs re-seating or the disk controller is faulty. First - re-seat the harddisk and reboot the computer. If this does not work then reboot and go to theBIOS configuration to see if the BIOS detects the hard drive. If it doesn'tdetect the hard drive then it could be faulty. Next - to determine if thehard drive is faulty, remove the hard drive and insert it into an USB hard drive adapter and connect it to a workingcomputer's USB port. If this computer cannot see itas an external hard drive and you cannot open the various folders and files,this confirms the hard drive is faulty. Then the hard drive needsto be replaced in the computer/laptop, Windows installed and the computer orlaptop's device drivers plus your programs etc. to get a functioningcomputer/laptop again.

What can I do to get my laptop to start up rather than a continual error message and re-boot cycle?

It is looking for the operating system on the hard drive and failing to find it in the system restore area.

If it does not find it, it will look on the DVD and or flash drive.

You need to make a backup of the operating system on to a DVD or flash drive from another windows 8 computer and put it in the computer to be repaired.

You can go to the manufacturers website to check if you have the very latest driver for your webcam. if not, you should be able to download it from there.

Go to control panel, then system properties, then device manager, then hardware. check imaging devices to see if your webcam is recognized.

Could be various causes just follow the information below and you should solve it.
Good luck

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
  1. Computer is booting from a non-bootable source.
  2. Computer hard disk drive is not properly setup in BIOS.
  3. Corrupt NTLDR and/or NTDETECT.COM file.
  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.
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 is in the computer, unless you are attempting to boot from a diskette.
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 and/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. Additional information about checking the CD-ROM drive connections can be found on document CH000213.
Additional information: 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 type of card reader or flash reader make sure that no memory stick is inside the computer.
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 XP users
  1. Insert the Windows XP bootable CD into the computer.
  2. When prompted to press any key to boot from the CD, press any key.
  3. Once in the Windows XP setup menu press the "R" key to repair Windows.
  4. Log into your Windows installation by pressing the "1" key and pressing enter.
  5. You will then be prompted for your administrator password, enter that password.
  6. 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:\

  7. 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.
  1. Boot the computer with a Windows 95, Windows 98 or Windows ME bootable diskette.
  2. At the A:\> prompt type:

    sys c: <press enter>

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

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.
