Blue screen - Unmountable Boot Volume

hi,I'm under Vista 32 bits and I'have a blue screen when starting. UNMOUNTABLE BOOT VOLUMEError 0x000000ed (0x878f6610,0xc00000b5,0x00000000,0x0000000)I can't boot and I can't load Vista. The Blue screen also appear on the Safe Mode.I can't enter into the Safe Mode.I also start with a boot cd disk and it takes very long time to load. I'd like to make a restoration, but i can do it. Really need your help to fix this issue, thank you.

I could fix it and now, my laptop seems to be running well.

When finnished running sfc /scannow , I got the following message : "Windows Resource Protection found corrupt files but was unable to fix some of them.Details are included in the CBS.Log windir\Logs\CBS\CBS.log. For example
C:\Windows\Logs\CBS\CBS.log"

Do you need the CBS.log ?
