• Type list partition and press Enter to view the partitions on the selected disk.
• Identify the partition that should be set as active and type select partition # (replace # with the appropriate partition number).
• Type active and press Enter to set the selected partition as active.
• Restart your computer and check if the "Bootmgr Is Missing" error persists.

Problems with Boot Order in BIOS/UEFI Settings

The boot order determines which devices the computer checks for an operating system during startup. If the boot order is set incorrectly in the BIOS or UEFI settings, the computer may not be able to find the boot manager and result in the "Bootmgr Is Missing" error.

To resolve this issue, follow these steps:

• Restart your computer and access the BIOS or UEFI settings. The key to access these settings varies depending on the computer manufacturer (common keys include F2, F10, Del, or Esc).
• Navigate to the "Boot" or "Boot Order" section.
• Ensure that the hard drive (containing the Windows 7 installation) is listed as the first boot device.
• If the boot order is correct, try changing the SATA mode from AHCI to IDE (or vice versa) and save the changes.
• Restart your computer and check if the "Bootmgr Is Missing" error persists.

Physical Damage to the Hard Drive or Storage Media

Physical damage to the hard drive or storage media can prevent the computer from booting and result in the "Bootmgr Is Missing" error. This can be caused by dropped laptops, power surges, or other physical trauma.

If you suspect physical damage, it's recommended to consult a professional data recovery service to retrieve data from the damaged drive and assess its repairability. In some cases, the drive may need to be replaced, and the operating system reinstalled.

Malware or Virus Infections

Malware or virus infections can corrupt critical system files, including the bootmgr file, and trigger the "Bootmgr Is Missing" error. It's important to regularly update and run a reliable antivirus program to protect your system.
