Installation to dedicated disk

[Peter Hillier-Brook]

It is my intention to create a dual boot environment where Windows XP 
resides wholly on the first disk (over several partitions, all NTFS) and 
Dapper Drake ubuntu resides wholly on a second disk, again suitably 
partitioned.

Previous experience with ubuntu (5.10) was that the installer, or Lilo 
would attempt to write to the MBR on the first disk, thus wrecking the 
Windows installation - not a bad idea, do I hear:-)

I want to ensure that Lilo, or Grub for that matter, installs only to 
the second, ubuntu disk and leaves my Windows boot sector alone: I will 
use the Windows XP Boot Loader to get to ubuntu.

Is it possible for me to be assured that this is possible, and that the 
Dapper Drake installation routine will be sufficiently explicit so as to 
militate against accidents?

Many thanks for any help with this.
