0xc000021a Blue Screen Loop

After defragmenting my laptop's hdd, (i was defragmenting the hard drive in windows pe) when i restarted, it was in a blue screen loop the error code is 0xc000021a as mentioned earlier. I tried system restore, but it was failing to restore it. It was saying that i try chkdsk c: /r but no luck... Is there anyway to fix this rather than re-installing Windows? Thank you for your suggestions.
