what happen to me was I accidently marked one of my iScSi drives as active so the server failed to boot. What worked for me to fix it was:
1. ใส่แผ่นติดตั้ง OS เข้าไป -> Boot from your Windows Server 2008 R2 x64 DVD.
2. เข้าเมนู Repair
3. เลือก Command Prompt
4. ป้อนคำสั่ง rename c:\boot\BCD bcd.old
5. Bootrec /RebuildBcd
6. diskpart
7. select disk 0
8. select partition 1 (the 100MB partition)
9. active
10. exit
11. reboot server and remove DVD
