Each time you start up your Dell Inspiron computer, the operating system accesses the Bootmgr to begin the boot process. When your computer reports that the “Bootmgr Is Missing,” it will prompt you to press a specific key to restart the boot process. Until your Dell Inspiron detects the Bootmgr or until you turn the computer off, it will continue to function in a start-up loop. You can troubleshoot your Dell Inspiron’s BIOS and Bootmgr file to fix the issue and allow your computer to start up.
If your Dell Inspiron attempts to boot from a DVD drive or a USB data device by default, it may display this error until you remove the media from your computer. You can access your computer’s BIOS settings and change the computer’s boot order to boot first from the Dell’s hard drive, rather than a media drive. Once you change the boot order, the computer will no longer read the DVD or USB drives first, which will prevent the Bootmgr error from happening in the future.
If your Dell’s BIOS is out of date, you can attempt to update your motherboard’s BIOS files to fix the Bootmgr issue. The update method varies depending on the motherboard model and the BIOS manufacturer. Because the BIOS is an important part of your computer’s file system, ensure that you download the exact update files from the manufacturer’s website and follow all update instructions exactly as provided. It’s also extremely import to make sure the computer remains powered on until the update is complete.
Windows Startup Repair
The Windows installation disc also provides an option to repair your computer’s Bootmgr file if it has become corrupted. Boot the computer with the disc in the DVD drive and choose to “Repair Your Computer.” The installation disc provides you with system recovery options including “Startup Repair.” When you click this option, Windows automatically scans and repairs any issues with your computer’s Bootmgr file.
Reinstallation and Hard Drive Failure
If the Windows Startup Repair can’t fix the issue with the Bootmgr file and you can’t log in to your computer at all, reinstall a clean version of Windows on your Dell computer. While installing a clean version of Windows will fix corrupted files, if you have corrupted sectors on your computer’s hard drive, this may be a sign of hard drive failure. If you suspect hard drive failure, back up important data files and replace the hard drive as soon as possible.
