Bootmgr is missing or corrupted: If Bootmgr is damaged or deleted, your computer won't be able to load Windows 7, and you'll encounter errors like "BOOTMGR is missing" or "BOOTMGR not found."
Accidental deletion or modification: If you've accidentally deleted or modified Bootmgr, you'll need to restore or repair it.
Virus or malware infection: Malware can damage or delete Bootmgr, preventing Windows 7 from loading.

Choose language, then click "Repair your computer".

Open "Startup Repair" first — allow automated fixes (run up to 3 times if prompted).

If Startup Repair fails, open Command Prompt and run:

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

If "Access is denied" on /fixboot, run:

diskpart
list vol
select vol X    (replace X with EFI or System Reserved volume)
assign letter=Z:
exit
chkdsk Z: /f
attrib -h -r -s Z:\bootmgr
copy Z:\bootmgr C:\

(Adjust letters per your volumes; Windows 7 typically uses a System Reserved partition.)

Check BIOS/UEFI boot order — ensure correct HDD/SSD is first.

Run CHKDSK on Windows partition:

chkdsk C: /f /r

If BOOTMGR reported as compressed, in Command Prompt:

compact /U C:\bootmgr

If partition table or disk failure suspected, use disk diagnostic tools (manufacturer's S.M.A.R.T. utilities) and consider imaging the drive before further repair.

If repairs fail and data is critical, stop and consult professional data recovery.
