Thanks for the clarification. Depending on the context, "MBR" can 
refer to the whole 512-byte section, ie. both the bootloader + 
partition table, or it can refer only to the bootloader.

I have a couple more questions:

1. I've read that to wipe out the bootloader, I should zero out the 
first 440 bytes: Why did you write 446? Are there extra bytes that I 
can zero out as well?

//This is what I use:
dd if=/dev/zero of=/dev/sda bs=440 count=1

2. In the -t1 option, does "prebuilt MBR" mean "Windows bootloader"? 
When restoring a Windows partition after playing with Linux (ie. GRUB 
as boot loader), I notice that even leaving this option unchecked 
does restore the Windows bootloader anyway. So I guess the -t1 option 
is only needed if, for some reason, the user needs to force 
Clonezilla to restore the Windows bootloader (equivalent to booting 
with Windows CD and running "fixmbr").

I suggest changing the text as follows:

[*] -g Reinstall GRUB bootloader in MBR on target disk (only if GRUB 
config exists in any Linux partition)
[] -t Clonezilla does not restore bootloader in MBR
[] -t1 Clonezilla restores prebuilt bootloader from syslinux (For Windows only)

Thank you.
