RAID+BOOT+Windows trouble

[|Quantum|]

Hey to all,

I have the following set-up:

MSI K8N Neo4 Platinum (Geforce4 chipset)
AMD Athlon 64 3500+
2 * 512Mb RAM
XfX GeForce 6800GT
2* Maxtor 160Gb SATA NCQ in a Stripe Set (NVIDIA RAID0)
1* Old HDD 1.1Gb IDE

The Stripeset is divided as follows:

Bootsector: Windows loader
Part0: 40Gb Windows
Part1: 40Gb ReiserFS with AMD64-Linux
Part2: 1Gb Swap
Part3: Data

Of course, I boot from the old harddisk which contains only bootsector and the contents mounted in /boot:
GRUB, kernel, initrd.

Now comes the problem. I can boot directly from the RAID0 into windows --> no problem.
I can also boot from the small IDE-disk, selecting Linux (with GRUB), which gives me Gentoo Linux.
But I can *NOT* select Windows from GRUB and boot from there.

I followed all the manuals... yet grub only prints the commands and then the PC hangs:

Since linux is booted from (hd0,0) == old HDD, I presumed I had to do this:

# Windoze
rootnoverify (hd1,0)
makeactive
chainloader +1

Exactly like all the manuals describe. I think it cannot find the bootsector on my RAID0.
For the moment I can help myself with the boot menu, but I'd like a nicer solution and I want to know what's happening here
Hence the question...

If I am correct you are using DMRAID for your RAID array?

Well grub doesn't recognize it, because its /dev/mapper/nvidia_xxxxxxx.

What you have to do is install Grub into the MBR of the Raid array. I did and I can boot windows fine.

Its great!

Good luck!
