Ps2 Master Boot Record Tool
For the following, suppose you have a plain, unmounted /dev/hdaN partition with some file system on it you wish to make part of a QEMU disk image. The trick is to dynamically prepend a master boot record (MBR) to the real partition you wish to embed in a QEMU raw disk image. More generally, the partition can be any part of a larger simulated disk, in particular a block device that simulates the original physical disk but only exposes /dev/hdaN to the virtual machine.

Here, a 1 MiB (2048 * 512 bytes) file is created in accordance with partition alignment policies used by modern disk partitioning tools. For compatibility with older partitioning software, 63 sectors instead of 2048 might be required. The MBR only needs a single 512 bytes block, the additional free space can be used for a BIOS boot partition and, in the case of a hybrid partitioning scheme, for a GUID Partition Table. Then, we attach a loop device to the MBR file:
Request Windows to boot in safe mode next time it starts up. This can be done using the msconfig.exe tool in Windows. In safe mode all the drivers will be loaded at boot time including the new virtio driver. Once Windows knows that the virtio driver is required at boot it will memorize it for future boot.
The FDISK command manipulates hard disk partition tables. The name derives from IBM's habit of calling hard drives fixed disks. FDISK has the ability to display information about, create, and delete DOS partitions or logical DOS drive. It can also install a standard master boot record on the hard drive.
It is currently not possible to manipulate EFI variables from within a running guest. For example, setting the boot-args variable by running the nvram tool in a Mac OS X guest will not work. As an alternative method, VBoxInternal2/EfiBootArgs extradata can be passed to a VM in order to set the boot-args variable. To change the boot-args EFI variable, use the following command:
Do you want to install or reinstall Windows 10 on your computer? Not sure how to prepare the bootable USB of Windows 10 without using third-party tools? In this step-by-step, we will see how to prepare the bootable USB of Windows 10 using the Command Prompt.
Followed the steps (even tried with Win 7 USB DVD download tool), boot priority is set to USB. But nothing happenes, disabled other boot options and it just skips to bios. Tried with multiple flashdrives, the USB socket must be working as well.
Boot sector restoration toolsBootsect.exe updates the master boot code for hard disk partitions in order to switch between BOOTMGR and NTDLR. You can use this tool to restore the boot sector on your computer
