Windows 7: System partiton was not found

System partiton was not found

I've not used many forums so bear with me please. I am also doing all this typing via my phone so sry for misspelled words.

Ok here goes. Three days ago I shut down my comp like normal. When I got home after. work and booted my system up all i got was a grey screen. I checked the monitor and graphics card, and they both checked out. So i created an ISO DVD. I ran the startup repair which told me "MBR is corrupted" and found the tutorial here that uses bootsect.exe. When i went looking for which drive was the dvd (which is G btw), I found a D drive NTFS partition backup of 86 mb but NO C DRIVE. I ran the bootsect.exe anyway but ended up with "system partition not found".

Please advise. I'm now stuck and not sure where to go from now.

I'm sry Vistaking, but as I've said many times now ... THESE TOOLS CANNOT FIND THE C DRIVE WHICH IS THE OS DEVICE. i also ran ur other suggestion with the pipe device and no result. None of the tools can find any files. For example, in cmd prompt i did c: <enter> followed by dir <enter> and the system had identifying info for the c drive but no files were found. So i cannot do what u asked.

OOC ... does Windows 7 use anything like a FAT file? Like used in old NT and 2K systems? If it does, is that NTFS or the MBR? Or something else?

Windows 7 uses NTFS by default . Fat file system is too old for Windows 7 . But it does use a Fat32 file system if you have a UEFI bios
