4.19.3. Alternative Boot Loaders
If you do not wish to use a boot loader, you have several alternatives:
You can load Linux from MS-DOS. Unfortunately, this requires a copy of the Linux kernel (and an initial RAM disk, if you have a SCSI adapter) to be available on an MS-DOS partition. The only way to accomplish this is to boot your Red Hat Enterprise Linux system using some other method (for example, from a boot CD-ROM) and then copy the kernel to an MS-DOS partition. LOADLIN is available from
ftp://metalab.unc.edu/pub/Linux/system/boot/dualboot/
and associated mirror sites.
SYSLINUX is an MS-DOS program very similar to LOADLIN. It is also available from
ftp://metalab.unc.edu/pub/Linux/system/boot/loaders/
and associated mirror sites.
You can load Linux using commercial boot loaders. For example, System Commander and Partition Magic are able to boot Linux (but still require GRUB to be installed in your Linux root partition).
Boot loaders such as LOADLIN and System Commander are considered to be third-party boot loaders and are not supported by Red Hat.
