[Solved] GRUB2 and Win 8 on raid 0

Question

Hello all,
Currently I have my system set up in the following config, (hd0) and (hd1) set up in raid 0 for my windows 8
install. Separately (hd2) is my arch linux install where I spend most of my time.
I have been choosing what system to boot into from the BIOS but this is cluncky and now I want to load windows 8 from GRUB,
when I run grub-mkconfig GRUB detects windows and creates a menu entry for it, but when I boot up the entry I only get
this.
invalid signature
Well I checked the wiki and there was a fix for the issue but the file that is supposed to be removed is not on my system. So
now I'm at a loss as to what the issue is. Below is my grub.cfg file and my /etc/default/grub, one thing I do notice about
this is that insmod mdraid is not part of the menu entry for windows when the wiki says it should be for raid. Is
there something that I am missing?

Answer 1

Thank you for the reply, it helped alot.
Here is what I did,
I used
# blkid
to figure out the UUID of the drive, OS-Prober was finding the correct UUID but the format was all messed up. The format of the menu entry that you linked to worked just fine, this is what I have added to
/etc/grub.d/40_custom
menuentry "Windows 8 Loader" {
insmod part_msdos
insmod ntfs
set root='(/dev/mapper/pdc_fibaedjhfp1)'
search --no-floppy --fs-uuid --set 2262C76C62C74371
chainloader +1
Everything is booting just fine, thanks for the help.
