[Solved] GRUB2 and Win 8 on raid 0

Anders H · 2013-05-21 04:15:09

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?

It seems that your menuentry for Windows is incomplete. Try to mimic this one

http://crunchbang.org/forums/viewtopic.php?id=18108

Also, ensure that you have the dmraid module (NOT mdraid) and doing again the os-prober stuff.

https://wiki.archlinux.org/index.php/In … _Fake_RAID

However, I'm more convinced everyday that Arch users should make their own grub.cfg overriding the auto-generated stuff, since it is absolutely bloated.

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.
