General comment:
The recovery diskette should be remade after major changes to ones system, that means after de-/installing hardware components or applications.

"...Please,could this be fixed,without make any format to C: ..."
First always try to run a repair, eg. re-install over the current installation. Usually therre is no need to format the partition.
You didn't mention which Windows version you are using. But probably you can still boot the emergency with the option "include cdrom support". then place your Windows cdrom into the cd drive. From the command prompt switch over to the cd drive (type the drive letter like C:<return>, then you may have to look for the setup.exe (use the DIR command to list the directory), possibly use CD command to go to the installation directory (\WIN\x86).
