Where is bootloader installed?
A boot loader is a program that is found by the system BIOS (or UEFI) in the boot sector of your storage device (floppy or hard drive’s Master_boot_record), and which locates and starts your operating_system ( Linux ) for you.
Which device should I choose for bootloader installation?
Under “Device for boot loader installation”:
- if you choose dev/sda, it will use Grub (Ubuntu’s boot loader) to load all systems on this hard drive.
- if you choose dev/sda1, Ubuntu need to be manually added to drive’s boot loader after installation.
Is a bootloader required?
– As mentioned above, the bootloader is needed when you need to have the possibility to update your firmware without having access to the programming header on the PCB and without the need to re-enable the security settings to allow this.
Where can I find Grub on my computer?
Grub can be installed anywhere but from default installed only in the MBR of the device. /dev/sda1 is not a device is a partition. It is not recommended for the bootloader to be installed in a partition.
Where is GRUB installed in a MBR disk?
The answer is considering an MBR setup, GRUB can be used in other setups. In an EFI setup things get hairy, GRUB can be used, but so can be the kernel itself as its own EFI stub. GRUB (some of it) is installed in the MBR. The MBR are the first 512 bytes on a disk.
Where does GRUB2 go when installing a new OS?
You have Grub2 installed in its own partition, as it should be. Normally, when installing a new distro, the wizzard will usually guide you through the installation process, and even figure out what partitions contain what OS-es, if applicable. The process on Arch is a bit more tedious but very well documented.
Where is GRUB installed in an EFI STUB?
In an EFI setup things get hairy, GRUB can be used, but so can be the kernel itself as its own EFI stub. GRUB (some of it) is installed in the MBR. The MBR are the first 512 bytes on a disk. The MBR is also used by the partition table of the disk, therefore GRUB itself has somewhat less space than the 512 bytes.
