This is if you used slitaz installer for a full slitaz install on your hard drive with grub.

Boot into slitaz live
Open terminal, be root.

 root@slitaz: grub

enter

 root@slitaz: find /boot/grub/stage1

enter
result of this is root,from what you say above sda3 = (hd0,2)

root@slitaz: root (hd0,2)

enter

root@slitaz: setup (hd0)

enter

root@slitaz: quit

Restart,you should see grub menu and be able to boot into slitaz on hard drive.
Open terminal, be root.

root@slitaz: nano /boot/grub/menu.lst

root@slitaz: fdisk -l

Whichever ntfs windows partition has the boot flag is what you will use for X in (hd0,X)
for rootnoverify in menu.lst
Grub starts counting at 0
I think it is (hd0,0) the system loader partition /dev/sda1
add this to menu.lst and save

title Windows Seven
rootnoverify (hd0,0)
makeactive
chainloader +1

Reboot, pick Windows from grub menu

i use winxp and grub4dos, have a look at my config:

c:\boot.ini

[boot loader]

timeout=10

default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS

[operating systems]

multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

C:\grldr="Grub4Dos"

c:\menu.lst

title Slitaz

find --set-root --ignore-floppies /boot/bzimage

kernel /boot/bzimage rw root=/dev/null home=4039-E1EC autologin lang=en_US kmap=us vga=789 screen=1024x768x24

initrd /boot/rootfs.gz

blank lines added in case of wraparound.
"home=" uses UUID.

sorry, double post.

@all :
will try those tonight and let us know.
thank you...

@mojo :
already tried, but still no luck :(

find /boot/grub/stage1
return error 15: file not found

root (hd0,2)
return filesystem type unknown, partition type 0x7

setup (hd0)
return error 17: cannot mount selected partition

and this is my menu.lst at sda3 :
default 0
timeout 8
color yellow/brown light-green/black

title slitaz gnu bla...
root (hd0,2)
kernel /boot/vmlinuz-2.6.30.6-slitaz root=/dev/sda3

heres my device.map :
(hd0) /dev/sda [my harddrive]
(hd1) /dev/sdc [my flashdisk]

please help...

@tikbalang :
wont work at windows7 64 bit architecture...

i'm not familiar with win7 and grub but i read somewhere that win7 uses the first partition as boot. if it uses boot.ini as winxp, maybe you can add grub there? it seems slitaz installer put grub to the PBR instead of MBR that's why win7 boot loader is still being started. menu.lst is useless unless grub can be started.

reading around, win7 does not use boot.ini at all but you can still add grub to win7 boot menu by using "bcdedit.exe".

if slitaz files are indeed in sda3, then your menu.lst seems okay.

For the commands to work you need these grub binaries in /boot/grub of /dev/sda3 (hd0,2)
The same locale where you found menu.lst and device.map

-rw-r--r-- 1 root root 8108 2008-12-06 16:53 e2fs_stage1_5

-rw-r--r-- 1 root root 9556 2008-12-06 16:53 xfs_stage1_5

If you don't see them try this command as root:
Make local mount point for /dev/sda3 ,in this example I use /media/skatebored

root@slitaz: mkdir /media/skatebored

root@slitaz: mount /dev/sda3 /media/skatebored

Verify mount:

root@slitaz: ls -la /media/skatebored

root@slitaz: grub-install --root-directory=/media/skatebored /dev/sda

The last command should first copy the grub binaries to /boot/grub, then run the setup from my previous post.
I tried this command in the past, sometimes the install failed because it didn't move the files.
This may be the reason slitaz installer fails to install grub.
If this doesn't work:
Verify the grub binaries are in /boot/grub

root@slitaz: ls -la /media/skatebored/boot/grub

If present rerun commands from previous post.
Not there copy them:

root@slitaz: cp /usr/lib/grub/i386-pc/*     /media/skatebored/boot/grub

Rerun commands from previous post.

@mojo :
those files are exist at my /dev/sda3 [/boot/grub/],
already tried to re-copied as you suggest but still no luck :(

@tikbalang :
at this point id agreed with tikbalang.
it keep bootin win7 because slitaz's loader is not found or somethin.
i did follow your suggestion using bcedit.
id added slitaz loader at win7 loader and it appear,
but im confused what file should i call for the first time?
already tried call /boot/grub/menu.lst but not workin.

some ubuntu's users are calling linux.bin file,
but i dont know what file should i call for slitaz?

please help...

thanks again for mojo & tikbalang :)

you need to call the grub bootloader. in grub4dos, this is called "grldr" (equivalent to winxp's "ntldr") and this has to exist in the root of the boot partition together with menu.lst.

from mojo's last post i think you can call one of the *stage* files. this looks like grub's loader.

if you don't mind a frugal install, i have a thread somewhere here outlining how to make slitaz "portable", with persistence. it's like booting from the livecd but i also works on usb and hdd.

The first time dualbooting I used grub4dos to chainload from Win2k boot menu-> C:\grldr->/boot/grub/menu.lst to boot full install of linux.
Required regular grub installed to the bootsector of partition with linux instead of MBR of drive.

halu...

already tried many ways, still wont works...
im very exiting bout slitaz,
but this loader is really #####

anyway, this the last bcedit conf i did :
C:\Windows\system32>bcdedit.exe

Windows Boot Manager
--------------------
identifier {bootmgr}
device partition=\Device\HarddiskVolume1

description slitaz

and the result is nothing but GRUB letters and nothing after that.

so anyone, please help...
thx b4

you are getting close. however, i am at my limits since i am not familiar with grub nor win7. you may have better success if you google "bcdedit grub".

i still offer the nomadic frugal method. the core slitaz files boot like a livecd but the home folder points to the boot partition to save userconfig. you can use it to install to hdd but you still need to figure out how to chainload from win7 bootloader. to keep installed apps you need to save the filesystem when logging out.
