Manual:

The fix should be also work in other cases, if u get the "Bootmanager missing" error messages, but in that situation, it was because u have a new HDD inside or put one HDD out of your PC, u still have a Windows on the HDD, but Windows show you problems like BootManager missing or something and dont wanna start your Windows on the HDD. So here is what u need to do...

  3. Write "diskpart" and press enter.

  4. Write "list part" then u see your Harddrives with a number behind the names.

  5. Write "select disk 0" the number based on the HDD what u wanna choice for windows.

  6. Write again "list part" and u can see the partitions (with numbers behind the names) on that HDD what u choiced before.

  7. Write "select part 1" the number based on the partition what u wanna use for windows.

  8. Write "detail part" then u see the informations about the partition and the partition should be now on "active: no" because of that, we must actived it.

  9. Write "active" and after pressing enter, its should be active now. To check it, u can write again "detail part" and on active should be now "yes", so your partition is active now.

  10. Now restart your PC & boot again from the Windows OS CD, if u forgot before to change the bios to boot from CD/DVD, u will get message like "bootmanager missing", then just go in your "Bios / Boot option" and change the "Boot option 1 to "CD/DVD" now restart and its should be boot from the CD.

  11. Then go again in the "repair option" the "systemrecovery option" search/check your HDD and then a Message should come, what says that windows found a problem at the Start option and its ask u, if u wanna repair it. Click on "Repair & Restart".
