I installed Debian instead of Mandrake, everything seemed to go well, except that reboot, none of the proposed partition GRUB does ... He says ERROR 21 disk does not exist for Linux and starting to leave Unrecognized Windows executable

You must make sure your boot or repair grub. Grub can not boot windows but it may ntldr to do so.
Error 21 means "Can not find disk". I would need a little more info to troubleshoot. What is your disk layout and could you post your /boot/grub/menu.1st file to have a look. Also what file types are you using? Ext3, Reiserfs etc.
You could try pressing your 'c' key on your keyboard when your Grub menu is up in your monitor. That will give you Grub's Command Line Interface. Follow the how-to in the link I just gave you and see if Grub will find your hard disks, partitions and Linux kernel, and boot your operating systems manually.
If you can do that, then you should alter your /boot/grub/menu.lst with the same commands your just used to boot up with.
If you cannot get a command line from your hard disk, you can use a Super Grub Disk, it can be used in GUI mode or Command Line mode or in, just press 'c', the same as for your installed Grub.
I hope that will be of some help to you. I have never tried RAID myself, so I don't know what it is like.
