Yes, to confirm, it was via SL menu re. "chainloader +1..." I thought that small difference was somewhat an indication the issue(s) was specific to SL menu creation and perhaps no deeper. (Aren't I naive?) Meanwhile, yes, a 'pure' Mandriva boot still works fine.

3 Ext DOS 12,143 100% (Mandriva)
4 Non-Dos 12,002 1 (truncated?) (Sabayon)

NOTE: Remember too, I still find Sabayon intact (appearing fully installed) through either openSuse or Mandriva's Dolphin file managers. -It's just that it won't boot.

Separately, one 'small' oddity I just noticed when touring via Suse/Mandriva Dolphins: The Sabayon's /boot includes another /boot alongside /grub, then that sub-/boot contains another /boot alongside another /grub, then that sub-/boot contains... (I only went down about 6 levels.) -Very weird! I don't think this happened the first install. And, I recall this happened w/ a Suse install once, and I simply deleted the 2nd level /boot and all was fine. (I think this may be a separate issue.)

Let's eliminate some easy stuff.

It's saying "File not found". I don't see where we've confirmed the files are there yet in this thread (I apologize if I missed it).

From one of your working installations (Mandriva or Suse), mount your Sabayon drive, and post the /boot directory contents:

Code: Select all
# ls -Fla <path-to-sabayon-partition>/boot/

My linux box is not accessible 'til perhaps this evening. Meanwhile, I recall seeing files in the /boot folder that coincided w/ menu (grub.conf) file called. i.e. from earlier notes: "initramfs-genkernel-x86-2.6.31-sabayon" and "kernel-genkernel-x86-2.6.31-sabayon"
-Are these what you are looking for? Also, recall this install worked just fine on a single drive by itself. (I think these issues are under multi-boot environments.)

Looking back at your third post in the thread, it does seem like grub is finding the kernel and initrd.

It might be worth while to try a simplified grub entry like:

Code: Select all
title Sabayon Simpler Boot (2.6.31-sabayon)
root (hd0,3)
kernel /boot/kernel-genkernel-x86-2.6.31-sabayon root=/dev/ram0 ramdisk=8192 \
        real_root=/dev/sda4 init=/linuxrc vga=791 console=tty1 verbose
initrd /boot/initramfs-genkernel-x86-2.6.31-sabayon


Leave off the "savedefault" default line for now.

DontPanic,
So, that works, but let's break that down a little more instead of 'playing tag' so much.
New grub.conf, tested once, 'right down the line'...
-------------------BEG--------------------
title Sabayon Simpler Boot (2.6.31-sabayon) - Okay, it boots but break it down as below....

title Sabayon (w/out "savedefault") (2.6.31-sabayon) - Works! (Boots just fine!)

...
-------------------END--------------------
I had actually tried modifying grub.conf entries to get it to boot -just never commented out 'savedefault' until now. -Go figure... Well, better late than never, as I was just about to pull the plug on this OS here.
It appears 'savedefault' is having some difficulties, probably hard-coded to look for a standard file/folder not created (or in same place) under the manual method. Are you one of the developers? Please remedy, of course. -I would have no idea... :?
Meanwhile, once booted, it appears as though most everything else is intact.
Although, remember a separate issue encountered during manual installation: The "Force to be a primary partition" checkbox option was not working properly -apparently instead always forcing a primary partition also when NOT checked.
Oh, and the /boot within /boot, within /boot, ... ? I just deleted the 2nd level /boot, but it may also be another issue for clean-up (?)

Please confirm fixes.
Thanks.

The 'savedefault' keyword is supposed to save the selection as the default the next time you boot.

Here's some documentation on it:

http://www.gnu.org/software/grub/manual/html_node/savedefault.html

If grub has trouble finding a file named /boot/grub/default on the grub root partition, apparently its gives off this kind of error.

Thanks for the confirmation -Apparently it's 'default' file is absent w/ a manually designed (assigned patititon) installation. I imagine we could make our own 'default' file and "limp along" from there...

Meanwhile add this and the other- (a) "Force to be a primary partition" checkbox, and (b) "/boot within /boot -issues, there's a lot of little "nuisance" issues we quickly encountered. i.e.: (c) Icons get re-shifted to upper, left of screen upon small changes to widgets, (d) Newly created icons just get piled on top of each other into the far upper, left corner of the screen, (e) When readjusted (reducing) icon size via settings, thse that were original icons are reduced but those we (right-click) copied from menu to desktop were not reduced. (We experienced none of these issues with other PSs like openSuse 11.2)
Now if these little issues are any sign, coupled with the deeper ones initially encountered, who knows what else... ?

We've looked into a lot of Linux OSs as a 'standard' for migrating from MS, not only openSuse and Mandriva. Sabayon's a nice concept- initially very attractive -but I think we'll need to go with openSuse as a 'standard' to start with -where we didn't experience any of these (or virtually any) issues. So, I believe this issue (all of these issues) are effectively closed for us here.

Thanks for all your input.
