2. WHAT IS NTLDR BOOTMGR ?
NTLDR (ABBREVIATION OF NT LOADER) IS
THE BOOT LOADER FOR ALL RELEASES OF
WINDOWS NT OPERATING SYSTEM FROM
1993 WITH THE RELEASE OF WINDOWS NT 3.1
UP UNTIL WINDOWS XP AND WINDOWS
SERVER 2003. FROM WINDOWS VISTA
ONWARDS IT WAS REPLACED BY THE
BOOTMGR BOOTLOADER.

3. WHAT IS THE FUNCTION OF NTLDR ?
NTLDR ALLOWS THE USER TO CHOOSE
WHICH OPERATING SYSTEM TO BOOT FROM
AT THE MENU. FOR NT AND NT-BASED
OPERATING SYSTEMS, IT ALSO ALLOWS THE
USER TO PASS PRECONFIGURED OPTIONS TO
THE KERNEL. THE MENU OPTIONS ARE
STORED IN BOOT. INI, WHICH ITSELF IS
LOCATED IN THE ROOT OF THE SAME DISK
AS NTLDR.

4. WHAT IS THE FUNCTION OF
BOOTMGR?
BOOTMGR IS RESPONSIBLE FOR LOADING
AND VERIFYING THE INTEGRITY OF THE
WINDOWS OS LOADER, WINLOAD.EXE.
IN THE WINDOWS OPERATING SYSTEM, THE OS
LOADER IS AN ESSENTIAL PART OF THE
OPERATING SYSTEM BECAUSE IT IS RESPONSIBLE
FOR LOADING PROGRAMS AND LIBRARIES. IT IS
ONE OF THE ESSENTIAL STAGES IN THE PROCESS
OF STARTING A PROGRAM, AS IT PREPARES THE
PROGRAMS FOR EXECUTION.

5. PICTURE SAMPLE

6. POSSIBLE CAUSES
1.UPGRADE ISSUES
2.CORRUPT HARD DRIVE SECTORS
3.MISCONFIGURED FILES
4.CORRUPTED OR DELETED NTLDR FILE
5.CORRUPTED BOOT SECTOR OR MASTER BOOT RECORD (MBR)
6. MISCONFIGURED BOOT.INI FILE:
7. IMPROPERLY CONFIGURED BIOS SETTINGS:
8. FAULTY HARD DRIVE OR IDE/SATA CABLE

7. III. SOLUTIONS AND PROCEDURES
BOOTMGR IS MISSING PRESS CTRL ALT DEL TO RESTART
BOOTMGR IS MISSING PRESS ANY KEY TO RESTART
COULDN'T FIND BOOTMGR
THE “BOOTMGR IS MISSING” ERROR DISPLAYS SHORTLY
AFTER THE COMPUTER IS TURNED ON, IMMEDIATELY
AFTER THE POWER ON SELF TEST (POST) IS COMPLETE.
WINDOWS HAS ONLY INITIALLY STARTED TO LOAD WHEN
THE BOOTMGR ERROR MESSAGE APPEARS.

8. III. SOLUTIONS AND PROCEDURES
HOW TO FIX ‘BOOTMGR IS MISSING’ ERRORS
1.RESTART THE COMPUTER
THE BOOTMGR ERROR COULD BE A FLUKE.
FOR WINDOWS 11, 10 & 8, USE THE POWER ICON FROM THE
START MENU TO SELECT RESTART.
FOR WINDOWS 7 AND VISTA, OPEN THE SMALL ARROW FROM
THE START MENU, AND SELECT RESTART.
YOU CAN ALSO RESTART YOUR PC FROM CTRL+ALT+DEL, OR
WITH THE SHUTDOWN /R COMMAND.

9. 2. CHECK YOUR OPTICAL DRIVES, USB PORTS, AND FLOPPY
DRIVES FOR MEDIA. OFTEN TIMES, THE “BOOTMGR IS
MISSING” ERROR WILL APPEAR IF YOUR PC IS TRYING TO
BOOT TO A NON-BOOTABLE DISC, EXTERNAL DRIVE, OR
FLOPPY DISK.
NOTE: IF YOU FIND THAT THIS IS THE CAUSE OF YOUR ISSUE
AND IT’S HAPPENING REGULARLY, YOU MIGHT WANT TO
CONSIDER CHANGING THE BOOT ORDER IN BIOS SO THE
HARD DRIVE IS LISTED AS THE FIRST BOOT DEVICE.
HOW TO FIX ‘BOOTMGR IS MISSING’ ERRORS

11. 3.CHECK THE BOOT SEQUENCE IN BIOS AND MAKE SURE THE
CORRECT HARD DRIVE OR OTHER BOOTABLE DEVICE IS LISTED
FIRST, ASSUMING YOU HAVE MORE THAN ONE DRIVE. IF THE
WRONG DRIVE IS LISTED FIRST, YOU COULD SEE BOOTMGR
ERRORS.
STEP 1: TURN ON OR RESTART YOUR COMPUTER
TURN ON OR RESTART YOUR COMPUTER AND WATCH FOR A
MESSAGE DURING THE POST ABOUT A PARTICULAR KEY,
USUALLY DEL OR F2, THAT YOU’LL NEED TO PRESS TO ACCESS
THE BIOS SETUP UTILITY. PRESS THIS KEY AS SOON AS YOU SEE
THE MESSAGE.

12. STEP 2: ENTER THE BIOS SETUP UTILITY
AFTER PRESSING THE CORRECT KEYBOARD COMMAND FROM THE
PREVIOUS STEP, YOU’LL ENTER THE BIOS SETUP UTILITY.
ALL BIOS UTILITIES ARE A LITTLE DIFFERENT, SO YOURS MAY LOOK
LIKE THIS OR IT MAY LOOK COMPLETELY DIFFERENT. NO MATTER
HOW IT APPEARS, THEY’RE ALL BASICALLY A SET OF MENUS
CONTAINING MANY DIFFERENT SETTINGS FOR YOUR COMPUTER’S
HARDWARE.
NOTE: SINCE EVERY BIOS SETUP UTILITY IS DIFFERENT, THE SPECIFICS
ON WHERE THE BOOT ORDER OPTIONS ARE LOCATED VARIES FROM
COMPUTER TO COMPUTER. THE MENU OPTION OR CONFIGURATION
ITEM MIGHT BE CALLED BOOT OPTIONS, BOOT, BOOT ORDER, ETC.
THE OPTION MAY EVEN BE LOCATED WITHIN A GENERAL MENU LIKE
ADVANCED OPTIONS, ADVANCED BIOS FEATURES, OR OTHER
OPTIONS.

13. STEP 3: FIND THE BOOT ORDER OPTIONS IN BIOS
LOCATE AND NAVIGATE TO THE BOOT ORDER OPTIONS IN BIOS.
STEP 4: MAKE CHANGES TO THE BOOT ORDER
NEXT, YOU’LL MAKE CHANGES TO THE BOOT ORDER.
STEP 5: SAVE YOUR BIOS CHANGES
BEFORE YOUR PREFERENCE TAKES EFFECT, YOU’LL NEED TO SAVE
THE BIOS CHANGES YOU MADE. TO DO THAT, FOLLOW THE
INSTRUCTIONS GIVEN TO YOU IN YOUR BIOS UTILITY TO NAVIGATE
TO THE EXIT OR SAVE AND EXIT MENU.

14. STEP 6: CONFIRM YOUR CHANGES
CONFIRM THE CHANGES AND EXIT BIOS.
STEP 7: START THE COMPUTER
START THE COMPUTER WITH THE NEW BOOT ORDER. WHEN YOUR
COMPUTER RESTARTS, BIOS WILL ATTEMPT TO BOOT FROM THE
FIRST DEVICE IN THE ORDER YOU SPECIFIED. IF THE FIRST DEVICE
ISN’T BOOTABLE, YOUR COMPUTER WILL TRY TO BOOT FROM THE
SECOND DEVICE IN THE BOOT ORDER, AND SO ON.

15. 4.RESET ALL INTERNAL DATA AND POWER CABLES. BOOTMGR ERROR
MESSAGES COULD BE CAUSED BY UNPLUGGED, LOOSE, OR
MALFUNCTIONING POWER OR CONTROLLER CABLES.
TRY REPLACING THE PATA OR SATA CABLE IF YOU SUSPECT IT MIGHT
BE FAULTY.
PATA, SHORT FOR PARALLEL ATA, IS AN IDE STANDARD FOR
CONNECTING STORAGE DEVICES LIKE HARD DRIVES AND OPTICAL
DRIVES TO THE MOTHERBOARD.
SATA (PRONOUNCED SAY-DA), SHORT FOR SERIAL ATA (SERIAL
ADVANCED TECHNOLOGY ATTACHMENT), IS AN IDE STANDARD FIRST
RELEASED IN 2001 FOR CONNECTING DEVICES LIKE OPTICAL DRIVES
AND HARD DRIVES TO THE MOTHERBOARD

16. 5.WRITE A NEW PARTITION BOOT SECTOR TO THE WINDOWS SYSTEM.
THIS WILL CORRECT ANY POSSIBLE CORRUPTION, CONFIGURATION
PROBLEM, OR OTHER DAMAGE.
THE PARTITION BOOT SECTOR IS AN IMPORTANT PIECE IN THE
BOOT PROCESS, SO IF THERE'S ANY ISSUE WITH IT, YOU'LL SEE
PROBLEMS LIKE "BOOTMGR IS MISSING" ERRORS.
IF THE PARTITION BOOT SECTOR BECOMES CORRUPTED OR
MISCONFIGURED IN SOME WAY, WINDOWS WILL NOT BE ABLE TO
START PROPERLY, PROMPTING AN ERROR LIKE ‘BOOTMGR IS
MISSING’, VERY EARLY IN THE BOOT PROCESS.

17. 6.RESTART YOUR COMPUTER WITH CTRL+ALT+DEL OR MANUALLY VIA THE
RESET OR POWER BUTTON. YOU MAY NEED TO REMOVE A DISC OR FLASH
DRIVE BEFORE RESTARTING.
7.REBUILD THE BOOT CONFIGURATION DATA (BCD). SIMILAR TO THE
PARTITION BOOT SECTOR, A CORRUPTED OR INCORRECTLY CONFIGURED
BCD COULD CAUSE BOOTMGR ERROR MESSAGES.

18. 8.CHECK THE HARD DRIVE AND OTHER DRIVE SETTINGS IN BIOS AND
ENSURE THEY ARE CORRECT. THE BIOS CONFIGURATION TELLS THE
COMPUTER HOW TO USE A DRIVE, SO INCORRECT SETTINGS CAN CAUSE
PROBLEMS LIKE BOOTMGR ERRORS.
NOTE: THERE'S USUALLY AN AUTO SETTING IN BIOS FOR HARD DISK
AND OPTICAL DRIVE CONFIGURATIONS, WHICH IS USUALLY A SAFE
BET IF YOU'RE NOT SURE WHAT TO DO.
9.UPDATE YOUR MOTHERBOARD'S BIOS. AN OUTDATED BIOS VERSION CAN
SOMETIMES CAUSE THE "BOOTMGR IS MISSING" ERROR.

19. 10.PERFORM A CLEAN INSTALLATION OF WINDOWS. THIS TYPE OF
INSTALLATION WILL COMPLETELY REMOVE WINDOWS FROM YOUR PC AND
INSTALL IT AGAIN FROM SCRATCH. WHILE THIS WILL ALMOST CERTAINLY
RESOLVE ANY BOOTMGR ERRORS, IT’S A TIME-CONSUMING PROCESS DUE
TO THE FACT THAT ALL OF YOUR DATA MUST BE BACKED UP AND THEN
LATER RESTORED.
11. REPLACE THE HARD DRIVE. THEN, INSTALL A NEW COPY OF WINDOWS.
IF ALL ELSE HAS FAILED, INCLUDING THE CLEAN INSTALLATION FROM THE
LAST STEP, YOU’RE MOST LIKELY FACING A HARDWARE ISSUE WITH YOUR
HARD DRIVE.
ASSUMING IT’S NOT A HARDWARE ISSUE, YOUR BOOTMGR SHOULD
BE FIXED. IF NOT THEN BETTER CONSULT AN EXPERT.

20. IV. PREVENTION AND PROPER MAINTENANCE
1.DOUBLE CHECK IF YOU PROPERLY INSERTED THE HARDWARE COMPONENT
2. KEEP THE COMPUTER CLEAN, AND PREVENT STATIC ELECTRICITY.
INSTALL THE NECESSARY ANTIVIRUS AND SYSTEM SECURITY SOFTWARE ON THE
COMPUTER.
DO NOT USE THE COMPUTER IN AN ENVIRONMENT WHERE THE TEMPERATURE IS TOO
HIGH.
3.MAKE SURE YOUR BIOS IS UPDATED.
4.PROPERLY CHECK YOUR SATA/IDE CONNECTOR IF IT IS CONNECTED PROPERLY.
5. KEEP YOUR OPERATING SYSTEM AND DRIVERS UP TO DATE
6. US RELIABLE AND UPDATED ANTIVIRUS SOFTWARE
7. BE CAUTIOUS WHEN MAKING CHANGES TO SYSTEM FILES
8. CREATE REGULAR BACKUPS

21. IN TODAYS WORLD TECHNOLOGY HAS BEEN A BIG PART OF OUR LIFE
WHILE IT CONTINUES TO IMPROVE IT ALSO FACES MANY PROBLEMS. AS A
RESULT OF IT MANY METHOD AND WAYS OF FIXING THOSE PROBLEMS
HAVE BEEN MADE. BUT MANY PEOPLE DON’T KNOW HOW TO FIX THOSE
PROBLEMS OR AND THE WAYS TO PREVENT THOSE PROBLEMS FROM
OCCURRING. THAT’S WHY THERE ARE PEOPLE WHO SPECIALIZES ON
THESE FIELD THAT GIVES ADVICES SO THAT THESE WONT HAPPEN
AGAIN. PEOPLE WITH PROPER KNOWLEDGE WILL KNOW HOW TO FIX
THOSE SPECIFIC PROBLEMS LIKE NTLDR/BOOT MGR. IS MISSING.
