How is the process of loading an image into a virtual machine?

Question

virtual box

DIY MBR

The system boot begins with the BIOS reading the first sector of the hard disk, placing it in memory at 0000:7С00h and transferring control here. Programmers call it the Master Boot Record, or MBR for short. At the beginning of the MBR is the machine code of the bootloader, followed by the Partition Table, which describes the scheme for partitioning logical disks. At the end of the boot sector is the 55h AAh signature telling the BIOS that this is indeed the MBR and not something else.

Can I in an imaging program (like brasero) create such an image with the MBR in the first sector?

Answer 1

You can.
