The first release of bootmgr.efi for the Windows Vista platform was on 11/08/2006 for Windows Vista. The latest version update [v10.0.16299.936 (WinBuild.160101.0800)] for Microsoft Office Access 2010 was 14 released on 07/04/2011. Bootmgr.efi is included in Microsoft Office Access 2010 14, Speakonia 1.3.5, and Free Convert to DIVX AVI WMV MP4 MPEG Converter 6.2.

In this short article, you will discover detailed file information, steps for troubleshooting EFI file problems with bootmgr.efi, and list of free downloads for every version that exists in our comprehensive file directory.

Runtime errors are Microsoft Office Access 2010 errors that occur during "runtime". Runtime is pretty self-explanatory; it means that these EFI errors are triggered when bootmgr.efi is attempted to be loaded either when Microsoft Office Access 2010 is starting up, or in some cases already running. Runtime errors are the most common form of EFI error you will encounter using Microsoft Office Access 2010.

In most cases, bootmgr.efi runtime errors occurring while the program is running will result in the program terminating abnormally. Most of these bootmgr.efi error messages mean that Microsoft Office Access 2010 was either unable to locate this file on startup, or the file is corrupt, resulting in a prematurely-aborted startup process. Generally, Microsoft Office Access 2010 will be unable to start without resolving these errors.

Finding the source of the bootmgr.efi error is key to properly resolving these errors. Although most of these EFI errors affecting bootmgr.efi will happen during startup, occasionally you will encounter a runtime error while using Microsoft Windows Operating System. This can occur due to poor programming on behalf of Microsoft Corporation, conflicts with other software or 3rd-party plug-ins, or caused by damaged and outdated hardware. Also, these types of bootmgr.efi errors can occur if it has been accidentally moved, deleted, or corrupted by a malware infection. Thus, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your bootmgr.efi issue. These troubleshooting steps are listed in the recommended order of execution.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many bootmgr.efi error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

If none of the previous three troubleshooting steps have resolved your issue, you can try a more aggressive approach (Note: Not recommended for amateur PC users) by downloading and replacing your appropriate bootmgr.efi file version. We maintain a comprehensive database of 100% malware-free bootmgr.efi files for every applicable version of Microsoft Office Access 2010. Please follow the steps below to download and properly replace you file:

GEEK TIP : We must emphasize that reinstalling Windows will be a very time-consuming and advanced task to resolve bootmgr.efi problems. To avoid data loss, you must be sure that you have backed-up all of your important documents, pictures, software installers, and other personal data before beginning the process. If you are not currently backing up your data, you need to do so immediately.

CAUTION : We strongly advise against downloading and copying bootmgr.efi to your appropriate Windows system directory. Microsoft typically does not release Microsoft Office Access 2010 EFI files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing bootmgr.efi and all other EFI files for Microsoft Office Access 2010. An incorrectly installed EFI file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.

-wimboot option stores the extracted Multi Windows Installers in their own directory. -bootmgr option moves the bootmgr and bcd files to root of drive. (note: -bootmgr option does require a Windows Vista or later host to run bcdedit).

The Legacy variant does not natively include files to make it UEFI Boot from USB. However, it is still possible to boot and run your Windows Installers from UEFI. To switch between added Windows versions, navigate to the multiboot/win-directory (replacing win-directory with the Windows version you want to boot) on your USB. Once there, move the bootmgr, bootmgr.efi, and entire boot folder to the root of your USB drive. Then reboot, booting your computer from the UEFI compatible USB. If all went well, it should boot straight into your chosen Windows Installer.

A significant step forward in the modification of bootmgr! There are 2 addresses from which all the disk ID information is taken, so the approach I took is to modify them in memory in Bochs, catching the write by the write watchpoint. 0x25554 -> this contains the MBR disk signature, change it to the GPT disk signature[1] 0x25550 -> has 0x01, got to change it to 0x00this will be used to match 0x1014c0 later, which contains the GPT disk signature. Making them identical allows the boot process to proceed to the next stageThe signature is written by instructions at 0x21bc(3-6) by the 16-bit stub, BEFORE bootmgr.exe loads. This same content is copied elsewhere AFTER it has loaded, by means of real-mode callbacks. The 0x01 is written at some other time, but you can modify that too along with the disk sig.Where this is writing from, I cannot tell because the values of segment offset registers make no sense to me, with my limited understanding. ds and ss are 0x60, and bx is 0x1764, but I don't know how word ptr ss:[bx+4] becomes 0x25554... (in fact looking at it, the brackets and everything don't even make any sense. )

I suppose some other place has the MBR info... If anyone has about an hour, a working Bochs copy, and a GPT disk with Windows 7 on it, and is willing to help out from this stage, please tell me : I'll write out detailed instructions.Meanwhile, the F8 menu works, and when seeing safe mode, I notice that the registry is the first file that it attempts to load, which immediately fails. So a strong indication of stale data.Fee Fie Fo Fum, I smell the blood of a hackable bootmgr![1] Do remember to use the correct endianness of the GUID... The rules are honestly completely crazy, so I suggest copying the on-disk representation from a hex editor, rather than using gdisk or diskpart

It seems somehow weird that winload.exe is happy being on a GPT disk while it's loaded by bootmgr.exe from an MBR disk, but isn't happy when bootmgr.exe is from the same GPT disk, which is convinced that it's ok.

The fact that your computer stuck at "Loading boot sector ...booting..." indicates your bootmgr.vhd may lack a valid MBR bootsignature (a boot sector). I suggest dumping the first 446 bytes ofthat image to verify whether it has the boot signature or not. Also,the sole partition on the virtual disk should be marked as "active",which can be verified by fdisk.

30 year tech pro here, who used to write technical documentation for elementary school teachers. I have a legacy logic board and my windows drive has no UEFI partition. So I wished to run Clover with my Windows 7 Pro version and eventually do an OSX Snow Leopard install on yet another SSD. I followed your directions exactly and installed Clover on both a USB stick and an internal Fat32 formatted drives. Each time, your Legacy installer confirmed a successful installation. However I was never able to boot from either drive into Clover, no matter what I tried in settings. If you read the comments that have been made here, you must realize that your instructions above need to be completely rewritten. When creating this kind of documentation, one must never assume another persons level of knowledge. This is the biggest problem experienced most by inexperienced technical writers. They assume far too much regarding their audience. You should try watching a non-technical person follow your instructions and see where and why they fail. Then, you really need to carefully read what you have written above and completely rewrite it. Maybe start with an explanation of the differences between UEFI and Legacy Bios and what these terms actually mean. Also, how the user can perhaps understand which type of hardware they are dealing with. Have a nice day.

not able to get secure boot option as i have LEGACY boot, can you help me out with that. If i need to get UEFI how will i get UEFI boot. having hp pavillion g6 laptop windows 10 pro with Insydeh20 setup utlity.

Hi Arjun,Thank you for your detailed explanation. I managed to make it work despite the /cow error after installing ChromeOS. Followed your advice to ignore it and copy the menuentry details. Worked fine. The only think not working at all is the microphone. Tried with different apps and websites. Do you know how to fix this? And also the clock of windows is not working properly as well.The machine is a Dell E7250 Intel i5-5300 with Realtek mic and audio. Thank you 2ff7e9595c
