Sounds like a toasted hard drive. You can dig around with grub. see grub commands:

If the MBR is not reading though, you may need to re-install and most likely buy a new HD.

Dell error Ox0000225


An unexpected error has occurred.
Boot selection failed because a required device is inaccessible.

how-to-fix-boot-error-0xc0000225.png
A general group of people will initiate a fresh install upfront. However, it is to inform you that the problem is not as severe as it seems. To recover from the situation, it would require a Windows installation disc, as you are already incapable to boot into Windows. Listed below are the possible solutions for this issue, depending upon the reason of its occurrence.
  • Rebuild Boot Configuration Data (BCD)
  • Configure Active Partition
  • Restore Master Boot Record (MBR)
Rebuild Boot Configuration Data (BCD)
The resolution is helpful, when your system is facing a spoiled Boot Configuration Data (BCD). In such a situation, it is recommended to rebuild this component of windows through command prompt. See below for a systematic procedure.
  • Insert Windows Installation Disk and Restart your computer
  • Select Time, Language, and click on the Next button
  • Click on the words stating Repair your computer in the lower left corner
  • Identify and access your system drive (For Example, C: D: E: etc.) and click Next
  • In the System Recovery Options box, choose Command Prompt
  • In the command prompt, type the command BOOTREC /REBUILDBCD and hit Enter
Configure Active Partition
The error 0xc0000225 may also result due to a wrong partition selected. The instance is that a user divides its storage device into several partitions. The BIOS must access the partition having system files on it (also called as System Drive). While accessing a wrong partition, it would end up in this issue.
  • Insert Windows Installation Disk and Restart your computer
  • Carry out the above given steps to reach System Recovery Options box
  • Among several system recovery options, choose Command Prompt
  • To set a correct partition, type the command line DISKPART and press Enter key
  • In the listed partitions, determine the one to be active and type following command line
  • SELECT PARTITION X (Let X be your desired active partition) and press Enter
  • Once the partition is selected, type the command line ACTIVE and then press Enter
  • Type QUIT and press enter to exit and then Restart the system
Restore Master Boot Record (MBR)
MBR is a boot sector containing information of logical partitions and file systems. An agitating MBR can also prevent you from normally booting into your Windows operating system. If this is the issue with your PC, try following steps to restore your MBR.
  • Insert Windows Installation disk and Restart your computer
  • Corry out the above given steps to reach System Recovery Options box
  • Among several system recovery options, choose Command Prompt
  • Enter the Diskpart and type the command line SELECT DISK 0 and press Enter
  • Now type LIST VOLUME and press Enter key to view a new list
  • Locate the CD/DVD-ROM under Type column and note down its letter under LTR column
  • Close Diskpart by typing Exit and pressing Enter.
  • Now access the CD Drive by typing F: and hitting Enter (Let F: be the CD/DVD-ROM letter)
  • Type and enter CD BOOT and then DIR to view the directory within the drive
  • Now type and enter BOOTSECT /NT60 SYS /MBR
  • Type Exit and press Enter
At the completion of process, you will see a success message saying, Bootcode was successfully updated on all targeted volumes. Now you must not have any issue while booting into your Operating system.

How do I fix error codes pxe-e61 and pxe-mof


The fix will depend on exactly what is wrong. The messages mean that your computer can't read the hard disc and find a boot OS. The drive may have failed, the cable might be loose, or the MBR (masterboot record) is bad.

First make sure that you do not have a CD/DVD in your optical drive, a floppy in your 3.5" drive or an external hard drive attached to one of the USB ports. (The computer may be trying to boot to one of them.)

Next press F2 when you turn on the computer (press repeatedly). This will let you enter the BIOS to set the disc boot order. (Check that the hard disk is listed first. This also indicates that the computer sees a hard drive in the machine.) If you get the error message again, try the entire procedure again from turning on the computer.

Next try using the appropriate Windows install/update disc to repair your system.(The Dell 4600 came with XP and you need the correct SP on the disc. If you kept up on the updates, it should be SP3.) Put the CD in the optical drive then restart the computer. Press F12 repeatedly to get the boot selection menu. (The same repeat routine may be needed if you miss the timing.) Use this disk to enter the Recovery Console and attempt to repair the Master Boot record.

Use the directions here: http://support.dell.com/support/edocs/systems/dim4600/en/4600i/sm/index.htm to check if the cable is connected properly. You will need to open the case.
This Dell came with an IDE hard drive. These often have a jumper that indicates the boot order. The jumper must be set to master or cable select and be attached at the master position on the IDE cable. This is the connection at the very end of the cable. The IDE cable can come loose from the motherboard, as well. You can also try a different cable.

The final option is to replace the hard disc. Unplug the old hard drive from the IDE cable first. You'll need the Windows install disc and then to reinstall all of your drivers and programs. Move the bad disc to the slave position on the IDE cable. See if you can salvage any of your files from the hard drive. (Sometimes, putting the drive in a ziploc bag and placing it in the freezer for several days will let you read the disk when you put it back in the computer.)

I hope this helps.

MRB Error message on Gateway laptop 6510GZ. how can we resolve?


First of all I'm not this smart. I found it and pasted it here for you from:
http://www.pcpowerguide.com/windows/damaged-mbr-error-message/

They get all the credit!

MBR is the acronym for Master Boot Record. The master boot record is located in the boot section of your hard drive, which is the first sector on the first platter. When you boot your computer, the master boot record tells the computer's BIOS (Basic Input Output System) where to find the bootstrap code for the operating system.
So if the MBR is corrupted, the BIOS can't find the operating system and you can get error messages like the following ones:
  • Missing operating system
  • Error loading system
  • Invalid partition table
Looks pretty scary, doesn't it?
However, it is usually not that hard to fix a corrupted MBR and usually the rest f the hard drive is just fine and will boot normally once your fix the master boot record.
What Causes Damage to the MBR? A lot of things can cause damage to the MBR such as viruses designed to corrupt the boot sector. Some of them copy the original MBR to another file. Others do this by overwriting the MBR with virus code. In fact viruses and malware are one of the most frequent causes but, any file can become corrupted especially files that are accessed as frequently as the MBR.
How to Fix the MBR The stapes to fix the MBR are slightly different in the different versions of Windows. So I will cover them separately.
Windows XP
  1. Insert your XP installation disk in the CD-Rom and reboot the computer
  2. When asked, press any key to boot from the CD
  3. When you get the Welcome to Setup screen, press "R" to open the repair console
  4. Enter your administrator password when prompted
  5. At the command prompt, type fixmbr and press enter
  6. When a new command prompt appears, type exit
  7. Remove your installation CD
  8. Restart the computer
Windows Vista
  1. Insert your Vista installation disk in the CD-ROM and reboot the computer
  2. When asked, press any key to boot from the CD
  3. When you get the Install Windows screen, fill in the language and location options and then click Next
  4. Click on the Repair your computer option
  5. Select the Windows Vista operating system and click Next
  6. Enter your administrator password when prompted
  7. In the System Recovery Options, select Command Prompt
  8. When a command prompt appears, type bootrec.exe and press enter to fix the MBR
  9. When a new command prompt appears, type exit
  10. Remove your installation CD
  11. Click Restart in the System Recovery Options window
Windows 7
  1. Insert your Windows 7 installation disk in the CD-ROM and reboot the computer
  2. When asked, press any key to boot from the CD
  3. When you get the Install Windows screen, fill in the language, Time and Keyboard Input options and then click Next
  4. Click on the Repair your computer option
  5. In the System Recovery Options, select Command Prompt
  6. When a command prompt appears, change to the boot directory
  7. Now type bootsect /nt60 SYS and press enter to fix the MBR
  8. When a new command prompt appears, type exit
  9. Remove your installation CD
  10. Reboot the computer

Computer says boot manager missing


Hello !
This can be caused by a big number of problems.
The easiest fix is to repair the bootloader and master boot records.
If you have a windows 7 DVD (doesn't matter what system you already have) use it and go to "Repair your computer".
Then open up "Command Prompt".
Type the following :
1. "bootrec.exe /fixboot"
2. Press ENTER
3. "bootrec.exe /fixmbr"
4. Press ENTER.
If this doesn't fix your issue, then something has been deleted from the operating system kernel (system32 core files). You can also use your operating system cd/dvd to "repair" this by re-copying the files.
Hope this helps, if you still have any problems, reply with comments. Thanks !
All the best.

While recovering my laptop 2910tx from recovery cd i got an error 0x4001100200001005. what should i do? install another version os, or other way?/


Since you didn't give much info I'll do my best. Did the error tell you that it couldn't find an operating system? Driver?
Reboot and enter "set up" change the boot order in the BIOS so that your cd/dvd is the first boot device. If you computer isn't destroyed you should get the recovery console then. Try getting into safe mode if possible and doing a system restore, or last known good configuration if you can't restore. If you can boot try those first if not then use the console and try to fix mbr.
MBR stands for Master Boot Record and it's the first sector of your hard drive that basically tells the BIOS where to look for the operating system on your computer.
If, for any reason, the MBR becomes damaged or corrupt, then the operating system will be unable to load. You will normally see error messages like:
Error loading operating system
Missing operating system
Invalid partition table
These messages are definitely not fun, especially if you are not familiar with computers. Most people would automatically assume their computers are dead! However, that's not true. Being in IT myself, these errors are actually preferably to other types of Windows errors. Why?
Well, it's actually fairly easy to fix the Master Boot Record in XP and Vista. All you have to do is load up the Recovery Console and run a simple command. All of your data, applications, settings, etc are still intact on the drive and once the MBR is fixed, the computer will load normally.
So how can you repair your damaged MBR? Here are the steps to follow:

1. First, restart your computer with the Windows XP setup disk in the CD drive.
2. When prompted, boot from the CD drive by pressing any key. If Windows loads automatically, you will first have to enter the BIOS setup and change the order of the boot devices to start with the CD drive.
3. Once the setup loads, you will see the option to press R to repair a Windows installation.
4. Once the Recovery Console loads up, you will have to type in a number that corresponds to your Windows installation. This is normally just 1. Press Enter and then type in the Administrator password.
5. Now at the prompt, type in fixmbr. Your damaged MBR will now be replaced with a new master boot record and your computer should now be able to boot properly. Note that you may also want to run the fixboot command to repair the boot sector with a new one.
Also, make sure you only use these commands on a system with one operating system installed. If you have more than one operating system installed, fixmbr and fixboot could mess up everything.
Fix MBR in Vista
In Vista (I'm assuming you have Vista) the procedure to fix the master boot record is a bit different. You have to start up Vista in the Recovery Environment and then run the bootrec command. Here's how.

1. First, load up the Windows Vista disc in your drive and press any key to boot from the disc.
2. Choose the language, time, currency, etc and click Next. Now click on Repair Your Computer.
3. Choose the operating system to repair and click Next. When the System Recovery Options dialog comes up, choose the Command Prompt.
4. Now type bootrec.exe and press Enter. This will rebuild the boot configuration data and hopefully fix your problem. You can also run the command with switches to fix just the master boot record (/fixmbr), the boot sector (/fixboot), or rebuild the entire BCD (/rebuildbcd).

Hope this helps.
If this helps you resolve your problem, please
consider giving me a good rating and a quick
"thanks" or "good job".It will help me as well.
Thank you.

My windows is not loading only a black screen when i start my pc


Hello,
Let us first find out what is wrong. This can be due to many reasons.

1) If the Caps lock, Scroll lock & the Num lock lights are blinking when you switch on your laptop, then, the problem is with RAM. It is either dislocated from the slot due to impact or not functioning properly.
If so, you need to open the back cover over the RAM slot while your laptop is off and unplugged. Remove the battery, pull the RAM chip(s) out and then place them back properly.
Fix the cover and the battery back and restart. Check whether it boots.

2) If it doesn't, restart it in a dark room to see that does it try at all to start. Is there any blink on the screen. If YES then insert the Windows installation disc to see whether it boots from it. If it does, so for so good. These steps may be helpful:

>>Select the region and language.
>>Just when it says install now, select Repair your Computer (for Vista & Windows 7).

>>It will scan for windows installations.

>>Select next.

>>From the Repair menu that appears select startup repair.

If the problem still persists, it might be with the Master Boot Record.

>>Reach to the Repair menu any way.

>>Select to open a command prompt window.

>>Type C: and press enter.
Then type diskpart and press enter to open the windows disk partitioning utility.
Then type list volume and press enter to view the volumes.
Then see the volume of the system & boot partition (Generally 1).
If the boot volume is marked as active type exit and press enter.

>>Now you are at the command prompt.

>>Now, type bootrec.exe/rebuildbcd and press enter. Windows will write a new MBR on the partition.

>>Next, type bootrec.exe/fixboot and press enter. This will write a new boot sector on your hard disk.

>>Next, type bootrec.exe/fixmbr and press enter. This will fix the bootstrap loader to the new Master Boot Record.

Type exit and press enter to quit command prompt and restart your computer.

The problem must be fixed.

Let me know what happens.
We are always available for your help.

We got the problem in our internal segate harddisk. when the system is on, shows the error message of Boot disk failure.


This sounds like a problem with the hard drive's MBR (Master Boot Record) If you have a windows xp disk, insert it and boot from it, make sure that your cd-rom device is set as the first in the list on your boot priority in your bios. Here are the steps for xp and vista

So how can you repair your damaged MBR? Here are the steps to follow:
1. First, restart your computer with the Windows XP setup disk in the CD drive. If you don’t have your original disk, borrow one or download a ISO image from a torrent site.
2. When prompted, boot from the CD drive by pressing any key. If Windows loads automatically, you will first have to enter the BIOS setup and change the order of the boot devices to start with the CD drive.
