The default boot options are adequate for most situations. The
installation program writes the
boot loader in the
master boot record (MBR), overwriting any
existing boot loader.
You may keep your current boot loader in the MBR
and install GRUB as a secondary boot loader. If you choose this
option, the installer program will write GRUB to the first sector
of the Linux
||GRUB as a Secondary Boot Loader
If you install GRUB as a secondary boot loader, you must
reconfigure your primary boot loader whenever you install and
boot from a new kernel. The kernel of an operating system such
as Microsoft Windows does not boot in the same fashion. Most
users therefore use GRUB as the primary boot loader on dual-boot
You may also need the advanced options if your
BIOS enumerates your drives or RAID arrays
differently than Fedora Core expects. If necessary, use the
Change Drive Order
dialog to set the order
of the devices in Fedora Core to match your BIOS.
On a few systems, Fedora Core may not configure the disk drive geometry
for large disks correctly because of limitations within the
BIOS. To work around this problem, mark the
The Linux kernel usually auto-detects its environment correctly,
and no additional kernel parameters are needed. However, you may
provide any needed kernel parameter using the advanced boot loader
For a partial list of the kernel command line parameters, type
