Not at all. GRUB4DOS can boot right from the DOS command line, after DOS has finished booting, or from config.sys or from autoexec.bat. It behaves as a common dos .exe program. Although you can install GRUB4DOS to the MBR or to the partition boot sector, it's by no means a requirement to do so. Read the Grub4dos Guide to learn more about it. XOSL is fine. But GRUB4DOS is way more versatile, and is an on-going project, for which there is a lot of support.Now, regarding Ghost (Norton Ghost up to 2003 or Symantec Ghost, afterwards), it can image from whole disks to individual partitions, and restore them perfectly. It depends what type of image you ask it to do. Once you have a full disk image you can only restore the full disk, though, and not just one specific partition from inside the image. But if you create and individual partition image, then it'll restore just that, and not mess with any other area of the disk. From the guide.... So to boot the HDD, it still uses the MBR. It's totally unlike EFI, OpenBoot, SRM, or many of the other advanced firmware procedures. The x86 BIOS architecture has major drawbacks, hence why x86 vendors want to go EFI so badly....
