Hi
I understand you (mostly).
0) How do i "install the MBR code as well and to activate your
partition."
1) "mount /dev/sda1 /mnt" -->> successfully completed.
2) "mkdir /mnt/extlinux" -->> successfully completed.
3) "extlinux --install /mnt/extlinux" -->> does not work.
Funny, but it it seems that there is no such thing as extlinux anymore.
Here is an Q&A that I got from the syslinux site:

I see that page needs a little work on terms.
Anyways, EXTLINUX is no longer a separate boot loader variant as its
functionality has been merged into SYSLINUX as of 4.00.
extlinux/extlinux is the SYSLINUX installer for mounted file systems
on Linux. linux/syslinux and mtools/syslinux are the SYSLINUX
installers for unmounted FAT* file systems on Linux.
So this puts me back in Square 1.
Thanks

But there is. extlinux is the installer that lives on but EXTLINUX was merged in. Did you try the above? What version? --Gene

[syslinux] installing syslinux on a fresh system (SATA)

There should be a single '*' in the 'Boot' column, in the row of sda1.

It's one of the various installers, see http://www.syslinux.org/wiki/index.php/EXTLINUX. If you don't use a separate boot partition on your disk (to be mounted under /boot), but use a single (ext2) partition for everything, then using /mnt/boot/extlinux above would be more natural. Syslinux does not care, though. -- Regards, Feri.
Thanks all, I did find extlinux in "my syslinux tarball" (I think that I understand my confusion now - I will explain at the end). So, now almost everything is fine...... Clearly my extlinux.conf is working (I can see my output on the console (SAY XXX)) I have a bzImage + rootfs.tar I tried : 0) mount /dev/sda1 /mnt/MyMountForSda1 -->> success 1) cd /mnt/MyMountForSda1 -->> success 2) tar xvf rootfs.tar -->> success 3) cp bzImage . -->> success 4) ls -->> success, looks like everything is in the correct place 5) reboot Here is my extlinux.conf prompt 1 DEFAULT linux LABEL linux SAY Now booting my first extlinux KERNEL bzImage APPEND ro root=/dev/sda1 When I reboot I see : Now booting my first extlinux -->> ( :-) ) boot: -->> ( here it stops :-(( ) BUT I can manually write "/bzImage" and press ENTER Now the kernel starts loading :-)))) (and crashes after 3 seconds, but that's a different story). So, it looks like my only issue (with extlinux) is to find the bzImage. What did I do wrong ? Maybe my extlinux.conf is not good ???? I also tried prompt 1 DEFAULT linux LABEL linux SAY Now booting my first extlinux KERNEL /bzImage APPEND ro root=/dev/sda1 but I got the same results........ Any advice ? It looks like I am on the edge.....
