Grub didn't work

Hi,

I have a notebook and I'm trying to use dual boot (Windows 7 Ultimate and ArchLinux).
I have succesfully installed Windows 7 and ArchLinux, but Grub didn't work well.
During the installation (also grub) everything appears fine and any error messages appears.
But when I boot my system it didn't find grub.

My hard disk layout is:

sda1 - Windows 7
sda2 - An extend partition (created by windows and I don't know why).
sda3 - /boot (ext2)
sda4 - / (resierfs)
sda5 - D:\ (Data)
sda6 - swap

At the first time I choosen sda3 (/boot) to install grub, but Grub didn't intialized and the chainloader pass the control for Windows 7.
After I choosen the sda (my hard disk) to install grub and the message "Operating System not Found" appears.
Someone can help me?

Does the grub (/boot) partition) have the "boot" flag?

With grub it could be alot of things but the first thing I would suggest is carefully reading the Arch grub wiki page which may give you your answer: http://wiki.archlinux.org/index.php/Grub

Re: Grub didn't work

The way I understand it :

If there is no boot manager (windows/grub/whatever) in the master boot record, BIOS tries to boot off the partition marked as bootable.

After installing grub to /dev/sda it should work, you probably have a wrong config. Try this:

title  Arch Linux
root   (hd0,2)
kernel /vmlinuz26 root=/dev/sda4 ro elevator=noop
initrd /kernel26.img
