Grub confusing disks...

I have five disks partitioned as follow : 

/dev/sda1:  Windows_7 
/dev/sda2: Archlinux 
/dev/sda3: LABEL="Store-Win" UUID="84F43132F43127B6" TYPE="ntfs" 
/dev/sdb1:     Linux 
/dev/sdb2:      Linux     
/dev/sdb3:      Linux 
/dev/sdb5:     Linux 
/dev/sdb6:     Linux 
/dev/sdb7:      Linux 
/dev/sdb8:     Linux 
/dev/sdb9:     Linux 
/dev/sdb10:     Linux 
/dev/sdb11:     Linux 
/dev/sdb12:    Linux 
/dev/sdb13:     Linux 
/dev/sdb14:     Linux 
/dev/sdb15:     Linux 
/dev/sdb16:     Linux 
/dev/sdb17:     Linux 
/dev/sdb18:     Linux 
/dev/sdb19: LABEL="Linux_Store" UUID="229CDBCBB04A5EA9" TYPE="ntfs"

the output of : blkid is as follow :

/dev/sr0: LABEL="ARCH_201208" TYPE="iso9660"

 

I've installed Archlinux on /dev/sda2 without a separate boot partition and the grub bootloader on /dev/sdb (My thought was to use Arch bootloader as a main bootloder and I've made an experiment)

I've installed the bootloader of every Linux_distro on the partition I've installed the distro. I boot to every Linux_Distro using "chainloader"
So I've created a 40_custom file

The old 40_custom file : 

#!/bin/sh 
exec tail -n +3 $0 
# This file provides an easy way to add custom menu entries.  Simply type the 
# menu entries you want to add after this comment.  Be careful not to change 
# the 'exec tail' line above. 

menuentry "Windows 7 (loader) (on /dev/hda1)" { 
	insmod part_mhdos 
	insmod ntfs 
	set root=(hd0,1) 
	search --no-floppy --fs-uuid --set=root 7CBEF651BEF60384 
	chainloader +1 
} 
menuentry "Debian GNU/Linux, with Linux 2.6.32-5-amd64 (on /dev/hdb1)" { 
	set root=(hd1,1) 
	chainloader +1 
} 

menuentry "SolusOS GNU/Linux, with Linux 3.3.6-solusos (on /dev/hdb10)" { 
	set root=(hd1,10) 
	chainloader +1 
} 
menuentry "Linux Mint 13 MATE 64-bit, 3.2.0-23-generic (/dev/hdb11) (on /dev/hdb11)"  { 
	set root=(hd1,11) 
	chainloader +1 
} 
menuentry "Debian GNU/Linux Testing (on /dev/hdb12)"  { 
        set root=(hd1,12) 
	chainloader +1 
} 
menuentry "SolusOS GNU/Linux Testing (on /dev/hdb13)"  { 
	set root=(hd1,13) 
	chainloader +1 
} 
menuentry "linux (on /dev/hdb14)"  { 
	set root=(hd1,14) 
	chainloader +1 
} 
menuentry "Debian GNU/Linux, with Linux 2.6.32-5-686 (on /dev/hdb15)"  { 
	set root=(hd1,15) 
	chainloader +1 
} 
menuentry "LinuxMint GNU/Linux, with Linux 3.2.0-2-amd64 (on /dev/hdb2)"  { 
	set root=(hd1,2) 
	chainloader +1 
} 
menuentry "Linux Mint 13 Cinnamon 64-bit, 3.2.0-23-generic (/dev/hdb3) (on /dev/hdb3)"  { 
	set root=(hd1,3) 
	chainloader +1 
} 
menuentry "Ubuntu Testing (on /dev/hdb9)"  { 
	set root=(hd1,8) 
	chainloader +1 
}

I could boot only to Archlinux and Win_7 (with an error message). For the rest I had the message from grub "Error: no such partition"

I've changed the 40_custom as follow (I changed the number of the disk with linux distros as to be the /dev/sda and no the /dev/sdb): 

menuentry "Windows 7 (loader) (on /dev/hda1)" { 
	insmod part_mhdos 
	insmod ntfs 
	set root=(hd0,1) 
	search --no-floppy --fs-uuid --set=root 7CBEF651BEF60384 
	chainloader +1 
} 
menuentry "Debian GNU/Linux, with Linux 2.6.32-5-amd64 (on /dev/hdb1)" { 
	set root=(hd0,1) 
	chainloader +1 
} 

menuentry "SolusOS GNU/Linux, with Linux 3.3.6-solusos (on /dev/hdb10)" { 
	set root=(hd0,10) 
	chainloader +1 
} 
menuentry "Linux Mint 13 MATE 64-bit, 3.2.0-23-generic (/dev/hdb11) (on /dev/hdb11)"  { 
	set root=(hd0,11) 
	chainloader +1 
} 
menuentry "Debian GNU/Linux Testing (on /dev/hdb12)"  { 
        set root=(hd0,12) 
	chainloader +1 
} 
menuentry "SolusOS GNU/Linux Testing (on /dev/hdb13)"  { 
	set root=(hd0,13) 
	chainloader +1 
} 
menuentry "linux (on /dev/hdb14)"  { 
	set root=(hd0,14) 
	chainloader +1 
} 
menuentry "Debian GNU/Linux, with Linux 2.6.32-5-686 (on /dev/hdb15)"  { 
	set root=(hd0,15) 
	chainloader +1 
} 
menuentry "LinuxMint GNU/Linux, with Linux 3.2.0-2-amd64 (on /dev/hdb2)"  { 
	set root=(hd0,2) 
	chainloader +1 
} 
menuentry "Linux Mint 13 Cinnamon 64-bit, 3.2.0-23-generic (/dev/hdb3) (on /dev/hdb3)"  { 
	set root=(hd0,3) 
	chainloader +1 
} 
menuentry "Ubuntu Testing (on /dev/hdb9)"  { 
	set root=(hd0,8) 
	chainloader +1 
}

And now I can boot to everyone Linux_Distro.
After this "solution" there is no problem, but it's not normal, it's not a "solution" and I can't trust myself (I'm afraid of partitioning mistakes??) and Archlinux.
It never happened with other distros.

PS. Sorry for a so long post and for my english.
