Grub4dos Guide - Loading/Installing Grub4dos From Linux

To load via Syslinux you will first need to install Syslinux to a bootable device (version 3.70 tested). Copy C:\Grub4dos\GRUB.EXE to the syslinux folder on the drive containing your Syslinux files and add an entry to the Syslinux configuration file syslinux.cfg. e.g. –

Alternatively copy C:\Grub4dos\GRUB.EXE to the root of the drive containing your Syslinux files and add following entry to syslinux.cfg –

Load Via (Legacy) Grub

Linux users with (Legacy) GRUB already installed can use it to boot Grub4dos. Identify the partition containing the GRUB boot files/folder (e.g. (hd0,0)/boot/grub). Copy grub.exe to the GRUB boot folder. Now add the following entry to your /boot/grub/menu.lst file.

Following was tested using ubuntu Linux (version 8.04 (Hardy Heron)) - kexec package was installed using terminal command sudo apt-get install kexec-tools -

Installing Grub4dos Code to the MBR

To install Grub4dos code to the MBR use bootlace.com. Using Puppy Linux version 4.0, (hd0) was identified as /dev/sda - Grub4dos was installed using the command /mnt/sdb1/bootlace.com /dev/sda. Output from running this command in a terminal -

Installing Grub4dos Code to the Partition Boot Sector

******************************************************************************
***           Use bootlace.com to install partition boot record            ***
******************************************************************************

Since bootlace.com has not implemented the --install-partition option, you
need to use the already implemented --floppy=PartitionNumber option instead.

Hear is a way you might want to follow:

Step 1. Get the boot sectors of the partition and save to a file MYPART.TMP.
	For NTFS, you need to get the beginning 16 sectors. For other type of
	filesystems, you only need to get one sector, but getting more sectors
	is also ok.

Step 2. Run this:

	bootlace.com --floppy=Y --sectors-per-track=S --heads=H --start-sector=B --total-sectors=C --vfat --ext2 --ntfs MYPART.TMP

	where we suppose MYPART.TMP is for (hdX,Y) and the partition number Y
	should be specified as in the --floppy=Y option.

	Note that for FAT12/16/32/NTFS partitions, you can omit these options:

		 --sectors-per-track, --heads, --start-sector, --total-sectors,
		 --vfat and --ext2.

	For NTFS partitions, you must specify --ntfs option.

	For ext2 partitions, you can omit --vfat, --ntfs and --ext2 options,
	but other options should be specified.

Step 3. Put MYPART.TMP back on to the boot sector(s) of your original partition
	(hdX,Y).


Note: Only a few file systems(FAT12/16/32/NTFS/ext2/ext3) are supported by now.

Note2: Under Linux you may directly write the partition. That is to say, Step
	1 and Step 3 are not needed. Simply use its device name instead of
	MYPART.TMP.

Note3: grubinst has the feature of installing grldr boot code onto a partiton
	boot area.
