Boot from an original XP cd, 1st option select "r" for repair. Select OS... Normally "1", then type in your administrator password, normally blank. when the command prompt is ready, type in "fixmbr" follow prompts and then type "exit" to restart.

See if that helps

What is MBR in dos


MBR stands for Master Boot Record

During the booting process MBR points the system from which partition it has to load the operating system

Mar 13, 2013 | HP Pavilion Computers & Internet

Tip

Master Boot Record


MBR Short for <i><b>M</b>aster <b>B</b>oot <b>R</b>ecord,</i> a small <a href="http://www.webopedia.com/TERM/P/program.html">program</a> that is executed when a computer <a href="http://www.webopedia.com/TERM/B/boot.html">boots up</a>. Typically, the MBR resides on the first <a href="http://www.webopedia.com/TERM/S/sector.html">sector</a> of the <a href="http://www.webopedia.com/TERM/H/hard_disk.html">hard disk</a>. The program begins the boot process by looking up the partition table to determine which <a href="http://www.webopedia.com/TERM/P/partition.html">partition</a> to use for booting. It then transfers program control to the <i>boot sector</i> of that partition, which continues the boot process. In <a href="http://www.webopedia.com/TERM/D/DOS.html">DOS</a> and <a href="http://www.webopedia.com/TERM/W/Windows.html">Windows</a> systems, you can create the MBR with the FDISK /MBR command. <br /> An <i>MBR virus</i> is a common type of <a href="http://www.webopedia.com/TERM/V/virus.html">virus</a> that replaces the MBR with its own code. Since the MBR executes every time a computer is started, this type of virus is extremely dangerous. MBR viruses normally enter a system through a <a href="http://www.webopedia.com/TERM/F/floppy_disk.html">floppy disk</a> that is installed in the <a href="http://www.webopedia.com/TERM/F/floppy_drive.html">floppy drive</a> when the computer is started up. Even if the floppy disk is not <a href="http://www.webopedia.com/TERM/B/bootable_diskette.html">bootable</a>, it can infect the MBR. <br />

Gateway zx4800 MBR is corrupt..error code = 0 x 57...too, need to know correct boot sequence


Windows installation CDs and DVDs have a number of system repair and recovery tools included that can get almost any computer back on its feet after a bad crash or faulty operating system installation. One very common problem that comes up when installing a second operating system is a corrupted Master Boot Record, or MBR. Windows System Recovery has tools that can fix a corrupted MBR, but if you don't have an installation CD or CD drive to put it in, you're going to need to copy the recovery materials to another medium, like a USB drive. If your MBR is corrupted, you probably don't have access to your Windows installation, so you'll have to follow most of these steps on another computer.
b> Insert the USB drive into another computer and run a command prompt window by typing "cmd" into the search box of the "Start" menu and hitting "Enter." Enter "mkdir X:\boot," and "mkdir X:\boot\sources" where X is the drive letter of your USB drive. Type "cd" and press the "Tab" key once, then hit "Enter." Enter "xcopy /H boot.sdi X:\boot," "xcopy /H Winre.wim X:\sources\boot.wim," "xcopy /H c:\windows\boot\dvd\pcat\bcd X:\boot," "xcopy /H c:\windows\boot\dvd\pcat\en-US\bootfix.bin X:\boot," and "xcopy /H c:\windows\boot\pcat\bootmgr X:\" to copy the necessary files to the USB drive. Enter "attrib -r -s -h /s X:\*" Enter "diskpart" to run the DiskPart program, then enter "list disk." The window lists the drives connected to your computer. Find your USB drive in the list and enter "select disk X", where X is the letter of your USB drive. Enter "list partition" to see the partitions on the drive and then "select partition X," where X is the number of the partition listed. Insert the USB drive into your computer and turn the computer on. Allow it to boot from the USB drive. You may have to set your USB drive as a primary boot drive in the computer's BIOS first. Enter your computer's BIOS (by tapping Delete or F2 during bootup, on most computers), then put your USB drive at the top of the "Startup" list. Go to the "Startup Repair" option in the "System Recovery Options" window. The "Startup Repair" process should correct your Master Boot Record and allow Windows to boot normally again. You will probably lose access to any other operating systems installed on your computer, though, since this recovery option is only designed to get Windows working again.
Hope this helps.

Trying to restore to factory settings. i pressed f8 but option "repair your computer isnt there"


try cntrl + F11 at start up

WHAT CAN CAUSE PC RESTORE TO FAIL?
If the hidden DSR (Dell System Restore) partition is removed


If the MBR (Master Boot Record) is modified in any way (such as if you load the Vista Upgrade over XP)


If you change the MBR but the pointers to the DSR partition are left, the DSR will boot, detect that the MBR has changes, and flash a screen that informs you that the MBR has changed and that image restore will not run


If you create additional partitions, changing the MBR, Dell PC Restore will be disabled to prevent it from overwriting these partitions that may contain critical data during a restore operation


If you add a second SATA drive and migrate to a RAID array using the Intel applications accelerator in windows, running PC Restore will put the image back on C:\, but the system will not boot since the boot sector is looking for the ATA driver (factory image) and the bios is looking for the RAID driver (migrated configuration)

If any of these occur, you cannot set the system back to Factory condition. You must manually load the operating system, drivers, and all application software.

My Acer netbook aspire one just shut down on its own one day. Now it will only stay on for 25 seconds before turning off by itself completely! I tried going to setup - 25 sec. Regular boot -- 25 secs Safe...


You may have a Virus, try a factory restore. As you know, the Acer computers and those of other manufacturers are now delivered with a system of restoration installed in a hidden partition of your hard disk. This system launches out while pressing keys ALT+F10 simultaneously. And sometimes for various reasons this system ceases functioning.
The first cause often comes owing to the fact that function D2D Recovery is disable in the bios (menu principal).

The solution : enable the function and try to press keys ALT+F10 during the starting of the computer.

The second cause : in this case hidden partition PQSERVICE was erased or damaged, or you replaced the disc and in this case it is not present.

The solution : If you did not previously make a backup of your system by making an image disc. It will not be possible to use the D2D recovery. Your only hope will be to have in your possession Acer Recovery CD/DVD.

And the third causes : the Acer Master Boot Record (MBR)was damaged or replaced by non-Acer MBR. As long as partition PQSERVICE is present or that you can put the hand on the necessary Acer files you can reinstall the MBR of Acer.

The solution :

First method : on a functional Windows system:

1 disable the D2D recovery option of the bios.
2 open a Windows session with an account administrator.
3 Download, unzip and launch partedit32(registration required for download).
markymoo: ptedit32


4 Identify the Pqservice partition by its size (at the bottom of the partedit window there is a partition information box) it is a small sized partition approximately 2 to 6 Go.Once made change the type of your partition into 0C and save. Restart and open a session with an administrator account, you should be able to navigate to the PQservice partition. Seek these two files mbrwrdos.exe and rtmbr.bin once localised open a command prompt and launch this command mbrwrdos.exe install rtmbr.bin, this will install the Acer MBR. Close the command prompt window restart again Windows go into the bios and reactivate the D2D recovery. Now ALT+F10 should launch Acer recovery at the starting of the computer.

Second method : On a nonfunctional Windows system.

For that you must use a Linux distribution (for me Mandriva provided all the tools necessary).

1 Boot on the Mandriva install CD/DVD the boot menu will give you the possibility to repair or to restore the Windows boot loader.
2 If that is not enough launch an installation of linux(this will be an occasion to test this terrible OS) and choose LILO as boot loader(a boot menu that allow you to choose between several operating systems) once finished the installation. Restart your computer in the boot loader menu system you will have at least 2 Windows options the first generally point to PQservice choose it and you will boot directly into acer D2D recovery. __________________

Restoring factory settings on a toshiba satellite ?? i was playing around with resizing the partitions and i goofed up and deleted the boot info bought a vista disk and installed windows vista. but i would...


Im not sure what exactly you have in the recovery partition ..but from what I know ..this is accessible by pressing F11 on boot ..and the info stored in it will restore the computer ..if you had vista in it before...probably will reinstall it ..so first just try to boot..and press f11 during the device displaying ..just like entering bios..and follow the instructions if it works..
another way is to install a clean operation system ...(the one that you use to have ..) by booting from cd ..(this will allow you to rearrange the partitions during install...in the moment when it sees previous OS ..and ask to choose a location for install..
after a clean install use the recovery cd that came with the laptop..
But..first try the recovery from that partition..if f11 do not work let me know and I will make some research in this matter ..

BOOT.INI default=signature (78c2dcdc)disk(0)rdisk(0)partition


I think the hard drive has no operating system on it or the MBR :Master Boot Record" is corrupt.
Try downloading "Hirens Boot CD" and burn to cd and boot from it.
It has a lot of useful Utilities on it for restoring MBR and formatting and partitioning
