Which of the following commands installs the GRUB boot files into the currently active file systems and the boot loader into the first partition of the first disk?
Which of the following commands installs the GRUB boot files into the currently active file systems and the boot loader into the first partition of the first disk?
To install the GRUB boot files into the currently active file systems and the boot loader into the first partition of the first disk, the appropriate command is 'grub-install /dev/sda1'. This command installs the GRUB boot loader specifically into the first partition of the first disk, which is represented by /dev/sda1. The other options are incorrect because they either refer to the entire disk, which would affect all partitions on the disk, or use invalid arguments.
I believe that the correct answer is B
The question says "currently active file systems", if installed on / dev / sda1 it will need to be added manually to the drive's boot loader after installation. Correct answer is A
full agree - its A
Agreed.
B. grub-install /dev/sda1 Install Grub files in directory /boot/grub of current partition. Install boot loader in first partition of first hard disk.
@rjlg2centos8 Check this explanation: https://wiki.centos.org/HowTos/GrubInstallation#Installing_Grub_using_grub-install . The correct answer is B.
That is correct B is the answer. https://debian-handbook.info/browse/sv-SE/stable/sect.config-bootloader.html#:~:text=Each%20partition%20is%20represented%20by%20its%20number%20on%20the%20disk%20on%20which%20it%20resides%3A%20for%20instance%2C%20/dev/sda1%20is%20the%20first%20partition%20on%20the%20first%20disk https://wiki.archlinux.org/title/GRUB#:~:text=Make%20sure%20to,the%20boot%20loader grub-install current is invalid, A is wrong since the partition is not specified
GRUB is installed to a device not a location so answer is A
This is a "tricky" question because it's asking about the grub installation and also It refers to the first partition, which all we know it's /dev/sda1, but the main idea of the question is about where the grub will be installed and it's focused on this last. So, starting from this point, grub only can be installed by referring to a device and not to a partition. In fact, on page 78 of the LPIC-1 book, it says: "To install GRUB Legacy on a disk from a running system we will use the grub-install utility. The basic command is grub-install DEVICE where DEVICE is the disk where you wish to install GRUB Legacy. An example would be /dev/sda." In conclusion, the right answer is A.
the answer is B it's asking about the first partition of first disk.
I think the corrext answer is A: The usage is basically very simple. You only need to specify one argument to the program, namely, where to install the boot loader. The argument has to be either a device file (like ‘/dev/hda’). For example, under Linux the following will install GRUB into the MBR of the first IDE disk: # grub-install /dev/sda https://www.gnu.org/software/grub/manual/grub/html_node/Installing-GRUB-using-grub_002dinstall.html
Grub can be installed to the "Device" only (not partition)
i think the answer is correct. Check LPIC 101-500 material page 71
its explained here: https://wiki.centos.org/HowTos/GrubInstallation#Installing_Grub_using_grub-install
I believe the correct answer is A: grub-install /dev/sda "run grub-install, pointing it to the boot DEVICE (NOT the partition) and the directory where the boot partition is mounted." source: LPIC -1 (101) Version 5.0 Learning Materials, Page 71
It is A. Why? Option B (grub-install /dev/sda1) is incorrect because it installs the boot loader to the first partition of the first disk, which is not where the boot loader should be installed.
The question literally asks it to be installed to the first partition on the first disk...
Could you explain better the answer please, thank you.
A resposta correta é B grub-install /dev/sda1 Instale os arquivos Grub no diretório /boot/grub da partição atual. Instale o carregador de inicialização na primeira partição do primeiro disco rígido. https://wiki.centos.org/HowTos/GrubInstallation#Installing_Grub_using_grub-install
This is what GPT-3 tells me. For example, to install the GRUB boot files and boot loader into the first partition of the first disk, you might use a command like this: sudo grub-install /dev/sda1
A is right for SCSI is going /dev/sda(dev/hda1) /dev/sdb(dev/hda2) /dev/sdc(/dev/sdb1) /dev/sdd(/dev/dfb2) ...
sorry for teh typo /dev/sdc(/dev/hdb1) /dev/sdd(/dev/hdb2)
The correct command to install GRUB boot files into the currently active file systems and the boot loader into the first partition of the first disk is B. grub-install /dev/sda1. Here's a breakdown of why the other options are incorrect: A. grub-install /dev/sda: This command would install GRUB onto the entire disk (/dev/sda), not specifically onto the first partition (/dev/sda1). This is generally not recommended as it can overwrite data on other partitions. C. grub-install current /dev/sda0: The "current" argument is not valid for grub-install. It's used for other commands like grub-mkconfig. D. grub-install /dev/sda0: This command would attempt to install GRUB onto the master boot record (MBR) of the disk, which is not the correct location for GRUB2 (the modern version of GRUB). GRUB2 typically resides in the first partition. E. grub-install current /dev/sda1: As mentioned earlier, "current" is not a valid argument for grub-install.
The 100% correct answer is "B" as i had this question in the exam 2024/03/19 ! - "A" would be only correct if the question would ask for Grub MBR installation ! ( grub-install /dev/sda ) - "B" asks for Grub Bootloader installation on 1st Partition on 1st disk. In this case it is /dev/sda1 ! https://wiki.centos.org/HowTos(2f)GrubInstallation.html All other answers are wrong !
This is a very basic question every Linux Admin should know by heart ! The moderator should change the answer in the Suggested Answer field as well.
