Thank You for answer.
very well. I have Toshiba Recovery DVD, but it is in Germany, because I bought it from there - and I don't like it.
I was trying to install W XP SP2 and also W XP MCE 2005 SP2 - the same thing... after all...when I did it... "leave the partition..." as You told - no format - it will ask me once more RAID DRIVER from A:... but no reaction!!!
with BIOS - I will look it... OO, I had a good look... now it is "kaputt" (crushed)

of course, I did some mistakes...I installed the german version OP from recovery dvd and during installation by my foolness I did also (mirroring) HDD=HDD...something like that...
now there is an information from DOS: (if I wanted to recover it once more from toshiba recovery dvd...)
in black window:
Handle RAID configuration...
- Mode GET1 F
- Flags 0x00 not 'F'!
Get current RAID state...
RAID Level = RAID-1 (Mirroring)
Status: Degraded
ERROR: KRC error configuring RAID!
Please go to BIOS to set a valid RAID configuration. (I tried all variants...but no success...every time the same...)
Press any key to continue...
end
HOW TO SOLVE THE PROBLEM???
