Question : restore from windows server backup and cannot run OS because of missing or corrupt ntoskrnl.exe

my windows small business server is down and I have to re-install a OS and get backup of C: and system status to try to make the server up to run. But after I install the basic OS and using windows backup to restore the c: and system status with original location and overwrite existing files, the windows cannot boot up because of missing or corrupt ntoskrnl.exe. I look into my windows .bkf file and do not see the file is backed up. Please help me for this case. Thank you very much.

No Proxy, tried the winsock reset, turned off firewall, removed card, nothing,
I had to reinstall.   Thanks for the comments.
