Please try Last Known Good now. If it still does not work, I suggest trying Registry to repair the system:

1. Put the Windows Server 2008 R2 installation disc into the disc drive, and then start the computer.
2. Press a key when the message indicating "Press any key to boot from CD or DVD …". appears.
3. Select a language, a time, a currency, and a keyboard or another input method, and then click Next.
4. Click Repair your computer.
5. Click the operating system that you want to repair, and then click Next.
6. In the System Recovery Options dialog box, click Command Prompt.
7. Type regedit and press Enter.
8. Select the key HKEY_LOCAL_MACHINE.
9. Browse into the System key, and then the CurrentControlSet subkey if it’s displayed.
10. Browse into the Services key and look for the likely offending service. Most service keys have a value named Start, with one of the following values:

• 0 Boot driver loaded by Ntldr (Boot)
• 1 Driver loaded at kernel initialization by Windows Server 2008 R2 (System)
• 2 Driver loaded at system startup by Session Manager or Service Controller (Auto Load)
• 3 Driver or service loaded manually from Services, Control Panel, and so on (Load onDemand)
• 4 Driver or service that is not running or started (Disabled)

Services with a Start value of 0 or 1 are used to boot Windows, and you shouldn’t touch them.
Services with a Start value of 2 start about the same time as the Login dialog box appears in Windows. If your Windows system boots and then promptly crashes without your help, try setting the Start value of any suspected service(s) to 3 or 4. Be sure to write down the names of the services and their original Start values before you change anything.

11. Exit Regedit.
12. Type exit and press Enter to close the Command Prompt window.
13. Remove the Windows Server 2008 R2 DVD and click Restart to restart your system normally.
14. If your system restarts correctly, you’re finished!

You might need to repeat this process a few times, disabling a different service or two each time.
