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

My daughters Asus eee pc MK90H notebook says windows could not start because system 32 is missing or corrupt. It says to use the original CD Rom, which obviously we dont have. Help what do we do?


Hi,
To restore a missing or corrupt ntfs.sys file you must have the Windows XP CD and follow the below steps.

Insert the Windows XP CD into the computer and restart the computer.
As the computer is starting make sure to press a key to boot from the CD.
In the Windows XP setup screen press the 'R' key to run the Windows Recovery Console.
If prompted enter the number of Windows installation you're repairing.
At the command prompt type the below command.

copy x:\i386\ntfs.sys c:\windows\system32\drivers

* In the above example you would replace x: with the letter of your CD-ROM drive. Many computers have the CD-ROM drive configured as the D: drive.

If ntfs.sys is still on the computer you'll be prompted if you wish to overwrite the file. If prompted, press the Y key for Yes to overwrite the file.
Once the file has been successfully copied remove the CD and reboot your computer.

Do NOT use an OEM "Recovery Disc". Only a valid Windows XP media will work or a disc from the OEM that says "Operating System" may sometimes work depending on how the manufacturer labeled the CD.

Hope this helps. Let me know if you need more information Thanks

What would make an hp laptop w/windows vista not turn on ,even tho its fully charged


So many things. Does it turn on at all or it just won't boot into Windows? If it doesn't turn on at all, remove the battery and run straight from the power cord. Make sure you are getting power to the computer.If you are getting power and the system turns on, but won't boot into Windows, trying booting into safe mode or using a recovery disk to start at a command shell. Remove the hiberfil.sys file and try to restart. The hiberfil.sys is a hidden system file so you'll need to use the following commands;
attrib -r -s -a -h hiberfil.sys
del hiberfil.sys

Try that. I just fixed a laptop last week and I had to delete the hibernation file in order to get the laptop to boot.

Dell 1501 vios2.6.2. reads missing operation system..then after 18 seconds it shutdown..pls..help... anybody has many opinion to fix it i appriciate it very much. tnks..


Missing operating system errors generally indicate a hard drive read failure. This could be for several causes.
  1. Hard drive failure (Run diags on the drive, if you get an error code, then time to replace)
  2. Software corruption (Too many possible causes to list
  3. Virus

So run Diags Fn+ Power, see if HDD passes diags, if it does, then boot to your windows CD and go to recovery console in XP, (Repair My Computer in Vista/7) in recovery console, run the command CHKDSK /R
If that doesn't resolve, then try a repair install of windows;

Acer aspire 5100 stops at agpcpq.sys and keeps rebooting. Will not boot up normally, safe mode, or any other way. Booted off of install CD and ran chkdsk /r. No luck.


Hi,
Boot from the CD again and this time run chkdsk /f
This command will try to fix any errors with the file system and check for and recover bad sectors.



Hope this helps.

Missing or corrupted file C:\windows\himem.sys


If you are running Windows 95, Windows 98, type:
copy himem.sys c:\windows <press enter>
If when typing any of the above commands you receive a prompt that the file already exists, ensure to overwrite it.
Reboot the computer; if the issue continues to occur, verify that the config.sys is properly setup. The line himem.sys should read:
DEVICE=C:\Windows\HIMEM.SYS
or
DEVICE=C:\DOS\HIMEM.SYS
Additional information and examples of the config.sys can be found on our autoexec.bat / config.sys page.

Laptop won't boot up


This is an operating system error, and sometimes indicates a hard drive failure. Start by running a system repair with your recovery or operating system disc. This usually takes care of it, if it doesn't, reformat the hard drive and install a new operating system. If you have any issues during or after the format or install, then the hard drive has failed and will need replaced.
