Administrator password I have this error message "BOOTMGR is missing" whenever I switch on my Dell Notebook and I tried to boot from a Bootable CD but I noticed it was disabled from the Dell Manufacturing Company alongside other ports that can be used for recovering a system. So I tried accessing the f12 for setup to enable the 'Boot from CD' but I was asked for an Administrator password, I tried my Window 7 password but it says 'Password Denied', now i"m stuck here and my system won't log me in... Please how can I get this Admin Password? Here is my Service Tag: 4F2N5S1 or Service Code: 9618561793 & my notebook mode is Dell Latitude E5420

Most likely cause is that the boot order in the BIOS is set up for the HDD first. When turning on the unit, press the key needed to enter setup. Once in setup, search thru the menus for the boot order. Choose the CD drive as the first boot device, then the hard drive as second. Save and exit the setup. When rebooting, ensure the WIN XP CD is in the drive. When the screen says, "press any key to boot from CD", press a key and the WIN XO CD should take over and start the install. Once WIN XP starts installing, follow directions. On each restart after that, DO NOT press the key to boot from CD. WIN XP setup will handle everything until the reinstall is complete. After you are done, you may choose to go back to setup and change the boot order back, but it is not really necessary. The only time you will get the "press and key to boot from CD" message is when there is a bootable CD/DVD installed in the drive. Otherwise, it overlooks it and goes to the next boot device (HDD).

Reset the password to get in. Use Hiren 15.2 disk to gaet into your computer control panel and make the changes in user accounts. Change password to new one or delete completely. Reboot to get in after removing the disk

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

hope this helps

What you need is bootable DVD/CD for installing or repairing Windows 7 to get missing 'bootmgr' or repair corrupted bootmgr...If there are files corrupt on your CD, you can get new one from shop you have purchased..Maybe just need to clean up your DVD/CD, so your DVD drives can read properly the files installation..

1.Insert the Windows XP CD-ROM into the CD drive, and then restart the computer.
2.Click to select any options that are required to start the computer from the CD drive if you are prompted.
3.When the "Welcome to Setup" screen appears, press R to start the Recovery Console.
4.Press 1 (One) to select windows XP and then hit enter.
5.When you are prompted, type the Administrator password. If the administrator password is blank, just press ENTER.
6.At the command prompt, Type Bootrec /RebuildBcd and then press ENTER.
7.If the Bootrec.exe tool runs successfully, it presents you with an installation path of a Windows directory. To add the entry to the BCD store, type yes. A confirmation message appears that indicates the entry was added successfully. 8.If the Bootrec.exe tool cannot locate any missing Windows installations, you must remove the BCD store, and then you must re-create it. To do this, type the following commands in the order in which they are presented. Press ENTER after each command.
Bcdedit /export C:\BCD_Backup

ren c:\boot\bcd bcd.old

Bootrec /rebuildbcd

1.Restart the computer

You have formatted the HDD in another computer and the “boot manager” was destroyed.
There is no operating system on the HDD and therefore the error message: “BOOTMGR is missing Press Ctrl+Alt+Del to restart" appears

The second message “PXE-M0F: Existing PXE ROM” says that the notebook tries to boot form the LAN but it’s not able to find an OS using the LAN connection!

Why all this error messages appears?!
Well, I think the CD/DVD drive cannot read the inserted WinXP CD and therefore in switches to LAN.

Note; You can boot from the drive by pressing the “C” button immediately after notebook starting or you will press the F12 to get the booting menu. Then you could choose the ODD as booting source.

If you will be not able to boot from your WinXP CD I assume either the CD is faulty or the CD/DVD drive cannot handle this CD.

Open cpu cabinet and Refix RAM some times bootable files not load on ram properly so this error comes.
So refix RAM memory clean dust from circuit and RAM .
Also pull cmos cell from motherbord for 5 minutes so all settings are defaults then check.
