GRUB is a bootloader. Most Linux distributions use it, though with UEFI becoming more and more prevalent, some users are abandoning GRUB in favor of simply allowing UEFI to load their kernel directly.
grub ana LILO are the two boot loader in Linux
GRUB error 15 is caused by the specified kernel or initrd not existing at the specified location. For instance, if the entry tries to load linux-2.6.22-18, but only linux-2.6.22-16 is present, Linux will not boot.
Before you format xp you will need to go onto Linux and create a grub boot disk by typing grub-install /dev/fd0. This will create a floppy disk which you can use to start Linux after you have removed and reinstalled xp. After removing and reinstalling xp use the disk to get back onto Linux and use grub-install /dev/hda to restore the Linux boot screen.
Grub Some times SysLinux, IsoLinux and other ***Linux Rarely LILO
GRUB error 22 is usually caused by deleting the partition that stage 2 of GRUB was stored on. You need to create a new partition and reinstall Linux in order to boot it again.
U-Boot is not actually part of Linux; it is a separate project. It is a bootloader, much like GRUB, often used in embedded devices.
GRUB is the bootloader for Linux operating systems. The bootloader is the section of code on the hard disk drive that is called and executed at bootup. It will load the operating system components and programs and start the operating system.
userdel -r or manually
For older versions it is "/etc/lilo.conf" and for newer versions "/boot/grub/grub.cfg".
Of course you can. The de facto standard bootloader, GRUB, is the reference implementation of the multi-boot specification.
Yes, I would suggest installing Linux last, makes it so you don't have to reinstall grub/grub2/lilo
