Well got same problem as above when try to boot an error message comes up and says no bootable devices insert boot disk and press enter but it says my hard drive is not installed tried the start up f8 but doesnt take me there any other suggestions

That error comes up when the computer cannot find the hard drive or any other device to boot from so it looks for a network booting program and when it cannot find that, the error shows up. REPLACE YOUR HARD DISK,

1 Remove any floppy disks or bootable CDs, DVDs, USB flash drives or other bootable media from the computer. Attempt to restart the computer again. Proceed if you continue to receive the error.
2 Restart the computer again. Press the key required to enter your BIOS setup. (The monitor usually displays a "Press [key] to access BIOS" right after restarting your computer. Press the key shown on your screen.)
3 Navigate to the "Boot Options" or "Advanced" menu by using the arrow keys. (The precise menu terms will vary according to your computer and BIOS type.)
4 Select the hard disk that contains your operating system (usually C:) as your primary boot device. Select your CD/DVD drive, your floppy drive or another hard disk as your secondary boot device.
5 Save and exit the BIOS. Proceed with the next step if you see the "Non-system disk error" message again.
6 Restart the computer. Return to the BIOS' "Boot Options" screen by following the steps above, then set the "CD/DVD drive" as the primary boot device and the hard disk as the secondary boot device. Save and exit the BIOS.
7 Insert your Windows installation disc. Restart the computer. Press any key to boot from disc. Follow the on-screen prompts to reinstall Windows.
8 Replace your hard disk drive if you cannot install Windows.

There is a loose connection between the hard drive and motherboard of the computer, that's why you are getting that message. You most likely need to take it to a computer repair shop so they can fix it.

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.

The PXE ROM is part of your system's network interface controller. It is being entered on your system's startup to look for a bootable image on a physical network connection and if found, to boot from that image. If there is no network cable connection to your system or if there is but no bootable device is found on that connection, the result is the error message that you got. As to why your system is entering the PXE ROM can be explained by looking at your system's Setup Utility,,,

Press F2 while powering up to enter the Setup Utility and use the cursor control keys to go to the Boot tab which then shows the Boot priority order. The default order is as follows...
1. IDE0
2. IDE1
3. USB FDD
4. USB HDD
5. Network Boot : LEGACY PCI DEVICE
6. USB CDROM
Your system's internal hard disk drive should be listed beside IDE0 and it will be accessed first to look for a boot record. If the drive fails to boot, the next devices in the list will be accessed accordingly until either a bootable device is found or the last item which is USB CDROM. If a USB CDROM is plugged in on one of the system's USB ports, it will be checked for a bootable record and if not found or no CDROM is plugged in, then the system displays the last part of the message -- insert boot disk and press any key.

Press F12 while powering up enters the Boot Menu which has the Boot Option Menu. This menu should show by default the following...
1. IDE 0: (the name/type information for your system's internal hard disk drive
2. Network Boot: LEGACY PCI DEVICE

If there is no hard disk drive information shown beside IDE 0, then the possibilities are that
1. there is no internal hard drive present
2. there is a hard drive but it has failed
If there is hard disk drive information and pressing enter to select it does not result in an operating system startup, then the drive's startup partition has been wiped and so it has no bootable image.

If there seems to be an internal hard drive present but it has no bootable image, you may attempt recovery from the installation images in the hidden partition. The recovery allows restoration of...
1. operating system to factory defaults
2. applications (selectable)
3. drivers (selectable)

Press Alt and F10 keys together while powering up and the Acer logo is showing to enter Acer's eRecovery Management. Follow the instructions to do the recovery.

Hello:
Your Acer laptop is not detecting a bootable device, for sure your hard disk is:
1.- Malfunctioning and has lost its master boot record.
2.- It can be ruined and must be replaced.

In the first case, primary and recovery partition are bad, as you mention the recovery process failed (ctrl +F11). First, press F2 during POST, when "a enter Setup message" is prompted on the bottom of screen to check if the hard disk is listed on the Main BIOS properties. If detected, the hard disk can be recovered booting from DVD-ROM. In the BIOS setup utility, you need to select boot from de DVD-RW. Insert Windows 7 setup disk and it will check for possible boot errors, choose repair when prompted. Follow the instructions. The system will restart.
If the hard disk was not detected in BIOS properties, you should ask Acer for guarantee.

If your computer has just been formatted, your computer might require you to insert the boot CD

to be able to run it. You might hence get the error message Disk Boot Failure- Insert disk and

press enter displayed on the screen every time you will try to run it. This might be linked

to:

* 1. The boot options not correctly set in BIOS
* 2. A non bootable CD is found in your CD drive
* 3. You do not possess any bootable device
* 4. You have installed a new hard disk
* 5. The hard disk is not properly plugged
* 6. Your system files have been infected
