Which tool should you use?
Definitely C
The question should state :
“You start Server1 by using Windows RE” (Recovery Environment)
Then :
/RebuildBcd
This option scans all disks for installations that are compatible with Windows Vista or Windows 7. Additionally, it lets you select the installations that you want to add to the BCD store. Use this option when you must completely rebuild the BCD store.
Note Use the Bootrec.exe tool to troubleshoot a “Bootmgr Is Missing” error. If rebuilding the BCD store doesn’t resolve the startup issue, you can export and delete the BCD store and then run this option again. By doing this, you make sure that the BCD store is completely rebuilt.
To do this, type the following commands at the Windows RE command prompt:
bcdedit /export C:\BCD_Backup
c:
cd boot
attrib bcd -s -h -r
ren c:\boot\bcd bcd.old
bootrec /RebuildBcd
