boot sector?

Question

Hard disks

Faced a problem.
There is a clean hdd, deployed windows7 to it (by unpacking boot.wim/sources.wim from a flash drive) and uploaded bootmgr.
I did this a lot of times - everything is OK, but only if any OS was already installed on the disk.
And on a clean screw he writes, they say, “insert boot media”, etc.
Rummaged through a bunch of forums, blogs - nothing helps (boorec, bootsect, testdisk, chkdsk).
As far as I understand, I need to correct the boot sector of the hdd itself.
Any solutions besides installing from disk?

Answer 1

And if it boots into recovery? There, Windows can fix such things automatically + if it doesn’t help, then the same recovery, console - and FIXMBR or FIXBOOT ... -)

Answer 2

The Windows CD contains the file boot\bootsect.exe
bootsect {/help|/nt60|/nt52} {SYS|ALL|:} [/force]
Allows you to install the /nt52 boot sector - Windows XP and earlier (ntldr) / nt60 - Windows Vista and later (bootmgr).

Answer 3

warp - thanks. Everything ingenious is simple.
Solved the problem by setting the disk active.
Wound on the mustache :)
