GRUB4DOS BOOT FROM MS DOS WINDOWS

In order to fulfill this objective, renaming two files is necessary. My objective was to load Grub loader first, before XP boot menu (and now before Vista boot menu). It simply requires renaming a couple of files, which I'll explain next why renaming is required. Fourth, Grub does not modify the MBR or PBR.

You can boot Windows PE 2.0 and VistaPE with Grub.

This is not a limitation of Grub at this point. Vista can load previous ones but not future ones.

It's backward compatible but not forward compatible meaning, XP can load Windows 2000, 98, and other legacy OSes but not Vista.

Grub can boot floppy, bootable CD/DVD (even if your BIOS does not support it), and floppy images from its menu.

You can't boot other devices, namely floppy and CD/DVD drive, from XP or Vista menu.

Grub4Dos loads Vista, XP, 2000, 98, Linux, BartPE on HDD or CD etc.

You can't boot non-Microsoft OSes with XP/Vista boot menu.

Why use Grub instead of Windows XP boot menu or Vista boot menu? There are several reasons. See the post at Multi-boot WinXP and other OSes with Grub4Dos for this method.ДЇor those of you not familiar with Grub4Dos (referred to as Grub henceforth), here's some background information on its benefits.

I've modified an old trick I've used to load Grub4Dos on system startup with Windows XP as the main OS. Good news for people who use Grub4Dos loader for multi-booting to various Microsoft OSes, including the new Windows Vista, and Linux.
