The other locations are not valid for the MBR, so options C, D, and E are all incorrect. The boot partition in any hard drive may contain a bootloader, but it is not the MBR, which is run first by the firmware thus option B is incorrect. Thus option A is the only correct answer. The Master Boot Record (MBR) is located in only one place-on the first sector of the first hard drive on the workstation. Finally, many workstations provide the PXE boot option, which allows the workstation to boot remotely from a network server. Modern workstations now also provide the option to boot from a USB memory stick inserted into a USB port on the workstation. Most workstations allow you to boot from an external hard drive or from a DVD drive. Normally, it looks at the internal hard drive installed on the system however, if none is found, it can search other places. The BIOS firmware can look in multiple locations for a bootloader program. The /proc folder is unique in that the Linux kernel dynamically stores information about the system there, but it doesn’t store boot log information there. The /boot folder contains the GRUB configuration files along with the image files necessary to boot the system, but it’s not where Linux stores boot logs and is thus incorrect. Some Unix systems use the /var/messages folder for storing log files, but Linux has not adopted this standard, so option B is also incorrect. The /etc folder is most often used for storing system and application configuration files, not boot logs, so option A is incorrect. Most Linux distributions store boot log files in the /var/log folder. Option E, the chkconfig program, is used to display the runlevels assigned to individual programs in the startup scripts and is not related to the boot messages, so it too is incorrect. Option B, the init program, is used to start programs from the kernel, not display boot messages, so it also is incorrect. The fsck program (option A) fixes corrupt partitions, and the mount program (option C) is used to attach partitions to the virtual directory, so neither of those is correct. The kernel ring buffer, which you can view by typing dmesg, contains boot messages from the kernel thus option D is correct. Option E also specifies a common Linux configuration file directory, but it’s not used to store the GRUB bootloader program that the firmware can access. Option C specifies the common log file folder, but that doesn’t contain the GRUB bootloader program. Option A specifies the configuration folder used to store the GRUB configuration file and the kernel image file, but the actual GRUB bootloader program can’t be stored there. The bootloader program itself can use the chainloader feature to look for another bootloader in a boot partition, but the firmware can’t do that, so option D is incorrect.

This is called the Master Boot Record, so option B is correct. The workstation firmware looks at the first sector of the first hard drive to load the bootloader program. The mount program is a Linux tool for attaching a partition to the virtual directory, which isn’t available until after the Linux system starts, so option D is also incorrect.

The Windows operating system only starts after a Windows bootloader program runs, so option C is incorrect. The init and telinit programs (options B and E) are used to change the runlevel of a running Linux system, so they aren’t useful until after the Linux system has started. The workstation firmware looks for the bootloader program to load an operating system.
