Veröffentlicht am Veröffentlicht in Allgemein, Windows

Have you ever experienced a boot loop with your Windows Server 2012 R2 machine? In most cases this occurs if your system’s boot record is corrupted.

First try if these commands help to fix your boot problems:

  • Insert a Windows Server 2012 Installation DVD or Recovery disk
  • Choose Repair, Command Line
  • enter the following commands:
    • bootrec /fixmbr
    • bootrec /fixboot
    • bootrec /rebuildbcd
  • restart your machine

If this won’t work (and you always get the message „Total identified Windows installations: 0“) try to get back to your last saved registry:

  • Insert a Windows Server 2012 Installation DVD or Recovery disk
  • Choose Repair, Command Line
  • enter the following commands:
    • cd c:\windows\system32\config
    • ren DEFAULT DEFAULT.bak
    • ren SECURITY SECURITY.bak
    • ren SOFTWARE SOFTWARE.bak
    • ren SYSTEM SYSTEM.bak
    • ren SAM SAM.bak
    • copy Regback\*.*
  • overwrite existing files? Yes
  • restart your machine
