If you are unable to find the Bootmgr on Windows 10, here are a couple of steps you can take to try and resolve the issue.
1. Check your BIOS settings: Make sure that your PC is set to boot from the correct hard drive and that UEFI/Legacy support is enabled in your BIOS settings.
2. Try using an automated repair tool: You can use the Startup Repair tool available in Advanced Options under Troubleshoot on the Recovery Environment menu to attempt repairs automatically.
3. Use a Windows 10 installation media: If both of these options fail, you can try using a Windows 10 installation media to repair your system. If you don’t have one, you can create it by downloading an ISO file from Microsoft’s website and burning it onto a USB or DVD drive with Microsoft’s Media Creation Tool or third-party software like Rufus.
4. Consider reinstalling Windows 10: If all else fails, reinstalling Windows may be necessary in order to fix any issues with the Bootmgr or other parts of your system that may be causing problems.

How do I fix boot manager missing without CD?
It is possible to fix boot manager missing without a CD. To do so, you would need to access the Windows Recovery Environment (also known as WinRE). You can typically access this environment by pressing F8 or F10 during the start-up process. Once the recovery environment has been accessed, select Repair Your Computer and then choose Troubleshoot > Advanced Options > Command Prompt. From there, you can enter in various commands that should help with resolving the issue of a missing boot manager. For example, you could try entering "bootrec /fixmbr" or "bootrec /fixboot". If these don’t work, you may need to use a system repair disc which can be created from another computer with the same version of Windows installed on it.
How do I get boot manager back?
If you have lost the boot manager, there are a few steps you can take to try and get it back.
First, check your BIOS settings to make sure that your hard drive is set as the first boot device. To do this, restart your computer and press the F2 key (or whatever key is indicated on the screen) to access the BIOS setup utility. Once in BIOS, look for a ‘Boot Order’ setting and make sure that your hard drive is at the top of the list.
Second, try running a Startup Repair from within Windows Recovery Environment (WinRE). This will scan your system for any issues that could be preventing boot manager from loading and attempt to repair them automatically. To access WinRE, turn on or restart your computer and press F8 or Shift+F8 repeatedly until you see an Advanced Boot Options menu appear onscreen. From here select either ‘Repair Your Computer’ or ‘Startup Repair’ (depending on which version of Windows you’re using).
Third, if none of these steps work then you may need to manually install boot manager by using a Windows installation disc or USB drive. Insert this into your computer’s CD/DVD drive or USB port respectively and then follow the instructions provided by Microsoft to complete the installation process.
I hope this helps!
What causes boot manager missing?
Boot manager missing can be caused by a variety of factors, including software or hardware corruption, accidentally deleting the boot manager files, incorrect BIOS settings, and bad hard drive sectors. To determine what is causing the boot manager to be missing, try following these steps:
1. Check your BIOS settings to make sure that the correct drive is set as the primary boot device.
2. Run a disk check on the hard drive for any bad sectors that may have corrupted data and caused the boot manager to go missing.
3. Scan your computer for any viruses or malware that may have affected system files and caused them to disappear from your computer.
4. If you recently updated an operating system or installed new software, it’s possible that this could have deleted necessary files from your computer leading to a missing boot manager issue. Try uninstalling recent updates or programs to see if this helps resolve the issue before restoring a backup of your previous OS version/software installation state if possible.
5. If all else fails then you may need to restore your computer back to its original factory settings which should reinstall all necessary system files including the Boot Manager back onto your machine
How do I fix Windows Boot Manager boot failed?
There are several steps you can take to try and fix the Windows Boot Manager boot failed error.
1. First, check that your hard disk is connected properly and that all cables are in good working order.
2. Then, restart your computer and press F8 while it is booting up to enter the Advanced Boot Options menu.
3. Once in the menu, select Repair Your Computer and follow the onscreen instructions to run a system restore or repair install of Windows.
4. If this does not resolve the issue, you may need to access your computer’s BIOS settings by pressing a certain key (usually F2) during startup, depending on your PC model or motherboard manufacturer. Here you should be able to see if the hard drive is detected properly by looking for it in either SATA Configuration or Integrated Peripherals section of BIOS Setup Utility screen.
5 .If still unsuccessful at this point, then try running a diagnostic program from a bootable USB device such as Ultimate Boot CD (UBCD) which can help diagnose hardware problems with storage devices like hard disks and SSDs as well as other components like memory modules etc.. Lastly if all else fails then unfortunately it may be time for a replacement drive!
Why does my PC say BOOTMGR is missing?
This error indicates that the boot manager is missing or corrupt. This can be caused by a number of different factors, including:
1. Corrupt or incorrect boot configuration data (BCD)
2. Damaged system files on the hard drive
3. A newly installed hard drive or other hardware changes
4. Unbootable Windows installation media such as a CD/DVD or USB flash drive
To fix this issue, please try the following steps:
1. Check your BIOS settings: Make sure your PC is set to boot from your hard drive first and not an external device like a CD/DVD or USB flash drive.
2. Run Startup Repair in Windows Recovery Environment (WinRE): Boot from your Windows installation media, select "Repair Your Computer" and then choose "Startup Repair". This will scan for corrupt system files and attempt to repair them automatically.
3. Rebuild BCD using Command Prompt in WinRE: If Step 2 does not work, then you can use Command Prompt in WinRE to rebuild the BCD file manually using the following commands: ‘bootrec /rebuildbcd’ followed by ‘bootrec /fixmbr’ and ‘bootrec /fixboot’.
4. Check disk integrity with CHKDSK command: Use Command Prompt in WinRE to check disk integrity with ‘chkdsk /r’ command, which will scan your disk for errors and attempt to fix any that it finds automatically.
If none of these steps help resolve this issue, then you may need professional assistance to diagnose and repair your computer’s hardware or software problem further before you can access Windows again on it successfully again
Why is my computer saying no boot device found?
It sounds like your computer is having difficulty locating a bootable device. This could be caused by several factors, such as an outdated BIOS version, corrupt operating system files, or a faulty hard drive.
To troubleshoot this issue I recommend the following steps:
1) Check to make sure all cables are connected properly and securely
2) Try updating your BIOS version if it is out of date
3) Attempt to run a disk repair utility (e.g., chkdsk or sfc /scannow command in Windows) to check for any corrupt system files
4) Check for any failed hardware components (e.g., RAM modules, hard drive, etc.) that may be causing the issue. You can do this by testing each component individually and then re-installing them in their proper slots/ports.
5) If none of these steps resolve the problem, you may need to replace the failing hardware component(s).
