Since Windows 2000, there have always been a total of 16 sectors in every
Windows Volume Boot Record Area; though on average, only about half of that area has actually been used for code and data, the remaining bytes always
being zero-filled.
Here we show every byte of the Windows 7 Volume Boot Record Area. The Boot Sector (or VBR
sector) is always first, followed by the BOOTMGR Loader's ("Bootstrap") sectors. If we include both data and code, the BOOTMGR
Loader is comprised of 3,624 bytes (Seven full 512-byte sectors + 40 bytes of an 8th sector). And if we include all the bytes of the VBR
sector as well, the whole Volume Boot Record Area's data and code are comprised of: 4,136 bytes.
If you open a disk drive that has Windows 7 installed on it, its first partition (and the VBR Area) will highly likely begin at Absolute Sector
2048. For all other partitions, you can use the Relative Sector numbers which are also shown in the table below. The Offset in
Memory column shows where every byte of a PC booting into a Windows 7 OS loads these 16 sectors into Memory (and how its Data Area appears
before execution):

All of the remaining 7 sectors (for a total of 16) are zero-filled (contain only
zero bytes). For the first partition of a Windows 7 OS disk drive, these would normally be Absolute Sectors 2057 through 2063, or
Relative Sectors 9 through 15 for any other partitions. So there are 4,056 zero bytes at the end of these 16 sectors [(7 x 512) +
(512 - 40) = 3584 + 472], or about half the total number of bytes in the Boot Record Area: 4,136 bytes of data and code plus 4,056 zero bytes =
8,192 bytes total.
Once again, the zero-padded bytes fill Linear Memory locations 0x8C28 through 0x9BFF during initial
boot-up.
It is not at all uncommon under a Windows 7 OS install, to find the following bytes at the beginning of the last sector of the C: Volume's Boot Record Area: "6B 87 08 38 76 C1 48 4E B7 AE 04 04 6E 6C C7 52" (with the ASCII characters: "nonic" also occurring twice at the offsets shown below). [Note: It would, however, be very unusual for any of this to occur in the VBR Area of a System Reserved partition.] The bytes "80 6E 6F 6E 69 63" (.nonic) also appear in ntoskrnl.exe (an NT Kernel & System file) and ntkrnlpa.exe (another NT Kernel & System file) and all their stored copies, the many other hidden files having the extension: "regtrans-ms" (Registry Transaction Log Files) in their file names and others.

The bytes at the beginning of this file correspond to the GUID label of:
{3808876b-c176-4e48-b7ae-04046e6cc752} in the machine's Windows Registry; where all the bytes within each dash-separated section,
except for the last one ("04046e6cc752"), are stored in little-endian format (reverse order) on the drive.
