Step 1:
There are a number of possible causes for BOOTMGR errors, including the most common "BOOTMGR is missing" error message.

The most common reasons for BOOTMGR errors 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

Anothe reason you might see BOOTMGR errors is if your PC is trying to boott 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. make sure there are no disks in cd floppy usb drives Test all power and data leads that attach to your hard drive IDE,SATA the leads from your ((MOTHERBOARD TO YOUR HARD DRIVE)) make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty if its a flat ribbon 40 pin IDE it will be the fist to fail Make sure all power and data leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty a computer needs Data and Power to travel through every working device and to continue its cycle and to have an end so any faulty leads will end up with a computer error. also make sure you have set it boot from you hard drive in BIOS Restart your computer and enter BIOS mode. On most computers this is done by pressing the Delete ot F2 key but will vary depending on your computers bios other keys Acer: - Ctrl+Alt+Esc , ALR PC: (F2) or (Ctrl)(Alt)Esc) , Award BIOS: (Del) or (Ctrl)(Alt)(Esc).

Scroll over to the "Hard Drives" tab, and make sure your computer has the hard drive assigned to be on. Often during BIOS you can select auto-detect or change options with your hard drive to make sure Windows can recognize it. Once you've selected your desired options, continue to boot.

Monitor will not boot up is reading no input signal


So either the computer isn't generating a video signal, the cable isn't carrying the signal to the monitor, or else the monitor isn't capable of receiving a video signal.To test this, first try a video cable that you know is good, in case your cable is bad, If it works with the other cable, the problem was your original video cable. If it still doesn't work, put your original cable back, and hook another computer up to the monitor. If the monitor makes the same message, the problem is with the monitor. If the other computer works when connected to this monitor, your problem was that the original computer isn't booting (which could be due to several reasons I will list below), or the video adapter is broken.Possible reasons for the computer not booting: bad power supply, bad power button, bad hard drive, bad memory, bad motherboard component. If you determine that it isn't booting, unplug everything except the keyboard mouse monitor and power cord, to see if that makes a difference. If it boots after that, something you unplugged was causing the problem, plug them each back in one by one, rebooting in between, and when it stops booting properly, the last thing you plugged in is causing the problem.

Yea sorry, forgot that tid-bit of info. It,s the W3118 eMachine / Gateway FIC K8MC51G


This issue can be caused by any of the below reasons.

-Corrupt boot files on the computer.
-Settings for hard disk drive are not correct.
-Floppy diskette or CD in computer causing issue.
-Boot devices not set properly.
-BIOS corrupt or misc. setting not set properly.
-Connections loose or disconnected.
-Bad Hard disk drive or other bad hardware.

Solution:


Corrupt boot files on the computer

If the computer has no bootable files on the drive it is attempting to boot from it is possible that the computer may halt at " verifying dmi pool data..."

To resolve this issue:

Boot from a bootable floppy diskette. Ensure that this diskette was made on the same Microsoft Windows operating system that is installed on your computer.

Once at the A:\> prompt type "sys c:" and press enter. This should report the message "File system transferred." Once transferred remove the diskette and reboot the computer.

If the computer continues to not boot attempt to re-create the master boot record by booting from the bootable floppy diskette again. Once at the A:\> prompt type "fdisk /mbr" and press enter. This should return you to the prompt without giving you any message. Once at the prompt remove the diskette and reboot the computer.

Note: The above information only applies to Microsoft Windows users. If you are running a Linux / Unix variant or other operating system such as OS/2 and the computer is freezing at this DMI message ensure that Linux / Unix has been properly installed first and/or your boot manger is not corrupt.

Settings for hard disk drive are not correct

The computer freezing at "Verifying dmi pool data..." may be caused when the hard disk drive settings within CMOS are not set properly. Enter CMOS and verify that the hard disk drive settings are set properly and/or that it is set to Auto Detect.

Floppy diskette or CD in computer causing issue

Verify no floppy diskette or CD is in the computer. In some cases the computer may be trying to boot from either of these drives causing issues with the boot sequence.

Boot devices not set properly

The computer stopping at " verifying dmi pool data..." can be caused when the boot devices on your computer are not set properly in CMOS. First, verify that no CD or diskette is in your computer. If a CD or diskette is in the computer attempt to remove this first to determine if it was attempting to boot from it.

If No CD or diskette is in the computer and your computer still halts at the DMI message enter CMOS setup and verify that the boot options are set properly. We commonly recommend that the floppy be set the first boot device, hard drive as the second boot device and the CD-ROM as the third boot device.

BIOS corrupt or misc. setting not set properly

If none of the above recommendations have resolved your issue attempt to reset the BIOS / CMOS settings to the factory or default settings.

Connections loose or disconnected

If the computer has been recently moved or new hardware has been installed in the computer it is possible that a connection may be loose or even disconnected. Verify that the hard disk drive, floppy and CD-ROM cables are properly connected.

Bad hard disk drive or other bad hardware

If you computer continues to freeze at the DMI message after attempting all of the above recommendations it is possible that the computer may be freezing because of a bad hard disk drive or other bad hardware in the computer.

Before replacing any hardware we first recommend you attempt to erase everything on the hard drive and start over.

If you're unable to get to the point of re-installing the operating system it's likely your computer has a hardware issue and it's suggested that the hard drive be replaced. If that doesn't resolve the issue then have the motherboard replaced.

Have emachines T6528 graphics problem


if it doesn't boot at all .( this is the reason that you see that message on the screen it means that no video signal came out from the computer ) ..try to change the cable that leads from the pc to the monitor first ...and if the problem its still on ...it have to be something related with the Ram memory or the CPU ....cause these 2 are the only things that can make a system to do not boot at all ...if any other device will not work ..the pc will still boot to bios ..or will still show the devices it finds on start ...even if is not able to succeed with the operating system boot...
so ...either it boots and you can not see anything cause the cable its damaged...( very possible cause this is the case it shows that message ...when the cable its shorted ..or unplugged ) or it doesn't starts at all cause of the memory or CPU ...

Computer will not boot up at all


Emachines have had a lot of problems with their power supplies going bad and destroying the motherboard in the process. If you can, start looking for a replacement motherboard (on eBay) and a larger wattage power supply (any local computer store) especially if you have experienced the computer shutting off or rebooting for no apparent reason. If you're lucky, you can try booting into safe mode by pressing the "F8" key on you keyboard during the boot process and select safe mode from the menu. If your computer boots up, then there exist the possibility of a corrupt video driver and/or corrupted file system. If you still can't boot and experience the same thing, then you may have a physical hdd problem or again, power supply, motherboard, or both. Also, do not over look the possibility of an internal fan on the video chip not turning. I hope this helps and good luck.
