Bootmgr is missing после клонирования диска windows

I have cloned my C: partition from an existing HDD to a new SSD using gparted from my Linux-SDD. This went well data-wise. I can see the files, yet the new Win7SSD is unable to boot.

At first, the cursor was blinking. When I set it to boot, it said bootmgr is missing.

Recherching further, I realized that my HDD has three partition, the expected C: for Win7 and D: for data; yet there is also a system-reservered bootable partition at 100 MB.

So I thought I could fix it via repairing the mbr. Hence, I tried entering the resuce prompt via Repair Computer and ran:

Bootrec.exe /ScanOs

yet this only lists C:, not E: as well.

I did not see a way to force BootRec.exe to do its magic on E:, I did run a /fixmbr and /fixboot while I was on E:, yet am unsure if this did anything at all on E: or if I «fixed» my working C: instead.

I still can boot from C: but I rather use my new SSD instead.

How can I make the SSD bootable?

» Dear Dennis,

I recently purchased an SSD (solid state hard drive) and wish to transfer my existing copy of Windows (from a standard hard drive) onto the SSD. I used Acronis True Image to clone the hard drive to SSD, but when I try and boot from the SSD, I receive the error message that ‘BOOTMGR is Missing’. I have also tried creating an archive backup of the original hard drive and then restored that to the SSD, but I have the same problem. How can I fix the ‘BOOTMGR is Missing’ error? «

My response:

This is a very common problem and affects both SSDs and hard drives equally the same whenever one drive is copied to another. The easiest way to fix the «BOOTMGR is Missing» error is to insert your Windows DVD or USB install media, then launch the ‘repair’ utility and have it scan your new SSD (or new hard drive) for startup errors. It should then automatically detect the problem and fix the master boot record (MBR) accordingly.

Here are the steps:

  1. Shut down and power off the computer; open up the case and then unplug all hard drives except for the new SSD (or new hard drive).
     
  2. Turn on the computer and insert your Windows DVD or USB install media. If you don’t have Windows install media, you can download it online for free from Microsoft, though there are some restrictions.
     
  3. OPTIONAL: you may need to enter the computer’s BIOS to change the boot sequence such that your DVD or USB drive will boot before the SSD (or hard drive), otherwise you will not be able to boot from the Windows install media in order to fix the ‘BOOTMGR is Missing’ error.
     
  4. Once the computer has been turned on and assuming you have adjusted your boot sequence properly, it should now start to boot from the Windows install media. You should see a message appear to «Press any key to boot from CD or DVD (or USB) …» Do exactly that, and the Windows install media should start booting.
     
  5. Shortly after, the main Windows install screen should appear. You will two options: one will be to «Install now», and directly underneath that will be a smaller options which reads «Repair your computer». Click the latter option to repair your computer.
     
  6. A new window will appear with the title «System Recovery Options». Choose the hard drive partition with your installation of Windows (usually the C drive), and click Next.
     
  7. The «Startup Recovery Options» window will appear. Click the link which says «Startup repair» / Automatically fix problems that are preventing Windows from starting.
     
  8. Windows will scan your new SSD (or new hard drive) and automatically detect that the boot sector has been damaged or is missing and will apply the appropriate fixes.
     
  9. When the process is finished, Windows will report that it made some fixes to the drive. To test the fix, eject the Windows install media and reboot your computer. Your new SSD or hard drive should now boot into Windows.

Note: if your new SSD boots but then either reboots in a continuous loop or if you receive an error screen, you may need to adjust the SATA controller setting on the main board to AHCI or RAID (which may also require you to reinstall Windows from scratch). In that case you will need to transfer your data over from the original hard drive manually onto the new one, rather than attempting to clone it. If you require help with that you can contact me and I will connect with you over remote desktop support.

Переустанавливать windows 7 желания не было, так что сделал следующее:

  1. Установил Acronis True Image Home 2010, создал в нем загрузочный диск.
  2. Создал диск восстановления системы, Пуск->Панель управления->Архивирование данных компьютера->Создать диск восстановления системы.
  3. Подключил SSD диск.
  4. Создал на SSD диске простой том и отформатировал его в NTFS
  5. Перезагрузился, загрузился с диска Acronis
  6. Клонирование диска не получится, т.к. размер старого системного диска больше нового SSD. Создал резервную копию старого системного раздела.
  7. Сделал восстановление из только что созданной резервной копии на SSD диск.
  8. В BIOS выставил загрузку с нового SSD диска, старый жесткий я отсоединил, т.к. в системнике и так куча винтов и свободного места для него больше нет, при желании его можно и оставить.
  9. При загрузке конечно же получил ошибку Bootmgr is missing
  10. Загрузился с диска восстановления, который я создавал в windows. При загрузке появилось сообщение «Обнаружены проблемы в параметрах загрузки этого компьютера. Хотите внести исправления и перезагрузить компьютер?» Нажал Нет. 
  11. В окне параметры восстановления системы нажал Командная строка.
  12. набрал diskpart <enter>
  13. набрал list volume <enter> в появившемся списке смотрю буквы у системного SSD и у дисковода (например SSD — G: дисковод H:)
  14. набрал exit <enter>
  15. набрал H: <enter>
  16. набрал copy bootmgr h:\
  17. перезагрузился

Теперь windows грузится успешно! Активация windows слетела. Теперь необходимо настроить операционную систему для работы с SSD диском.
