I've installed Arch in the same hdd where there were installed Debian and Win7. I've done the update-grub in Debian, Arch installation is been founded and everything seems ok.
But when I try to boot Arch via grub, randomically it fails to found the Arch partition, while for Debian and Win7 I haven't any problem. What can I check? Can you help me?

Can you show your grub file config

This is my grub.cfg in debian installation.

Up!
The problem is not solverd but is randomic: sometimes I have to reboot 5-6 times ti login in Arch, sometimes all goes well at first attempt...

It strikes me odd that Arch is on hd0 and sdb. hdo should be the first hard drive and sdb the second in my understanding
Why don't you try disabling os-prober in Debian and uncommenting the lines in /etc/grub.d/40_custom beginning with menuentry... Then rebuild grub.cfg (I think Debian uses update-grub for this). Using the UUID (assuming it is the correct one - you can verify with the blkid command) should bypass drive and partition identification problems.
To disable os-prober, add the following line to /etc/default/grub (or other similar grub configuration file there - as names might be different in Debian).
GRUB_DISABLE_OS_PROBER=true
