If the first byte is 0xEB or 0xE9 (long or short jump) usually you have a B=
oot=20
Record.
If the first byte is 0x00 or 0x33 (first byte of XOR AX,AX) usually is a MB=
R.

But if you have an SD prepared with Grub will find 0xEB at the start of MBR=
....=20
this is unusual!

Try to read sequentially from first sector and stop when you find the boot=
=20
sector: you can identify it, in first instance, because of his signature: 0=
x55=20
and 0xAA the last two byte.
Maybe this can help you to find something...
