The Grub necessarily must be installed in to / or /boot of Siduction.
Installed in to / or /boot of Sidution, must be recognized by your other boot loader.
Revised April 6, 2013:
Having used the Debian Installer for each stable release since Sarge, I was used to having to specify the location for LILO/GRUB. With Siduction, that is not necessary.
I use the third primary hd partition for /boot with / having its own separate partition in the extended region. This is because LILO had required being installed in a bootable partition - GRUB has been OK with this arrangement too.
I had read, years ago, and still see the recommendation to put GRUB (or LILO) in a separate ext2 partition because the boot loader is static and journaling was unnecessary and/or could slow down hard drive response. The / partition could then be put anywhere else on the hard drive, even an extended partition, using an ext3 or ext4 file system.
With Siduction, that approach caused some problems. Also, I was not understanding clearly what the installer was doing.
PROBLEM ONE:
/usr/sbin/grub-bios-setup: Warning: File system 'ext2' doesn't support embedding. I am not quite sure what this means or if it only happens when / is installed in an ext4 partition (I have not used ext4 before and I never saw it when using ext3 with native Debian). I only used ext4 because it was recommended in the Siduction manual, even though I felt more comfortable with ext3 (I am trying to move forward with the technology).
PROBLEM TWO (ME):
The bigger problem was me not understanding the Siduction installer:
After confirming the partition layout, the installer asks to select the partition and file system type for the root file system. That is pretty straight forward. Again, I selected ext4 over ext3 because it was highly recommended in the manual.
Mount Point Definitions is where I got myself into trouble. Besides using a separate partition for /home, I used a separate primary partition for /boot. Because of my previous experience with the Debian Installer, I thought that I would later have to specify the device (i.e. /dev/sda4) where GRUB was to be installed.
What I finally figured out was that because the /boot partition (/dev/sda4, in this case) would be integrated into the / file tree, when it was time to choose the location for GRUB, in the next step, *Partition* was the correct choice. The Siduction installer would know to install GRUB into /boot (a.k.a. /dev/sda4) without any further instructions.
My preferred boot loader (Plop) is not a Linux loader but can recognize and chain load GRUB/LILO.
Had I understood this better for myself, I may have had a working Siduction system by now. Since I tend to learn the hard way (trial and lots of errors), I suppose the multiple chroot exercises and numerous re-installs are all part of the learning process.
