hi,
i have a lenovo s430.
i have SSD msata and a sata.
i would like to install win (7 or 8) on msata and linux (suse 12.3) on another ssd drive.
i suppose grub 2 should be installed on the ssd, 2 entry will be available?
any tips?
thanks

You might check today’s announcement about RC2, as it talks about the
status of UEFI support.

If you plan to install windows 8 along with openSUSE have a look at
Linux and Windows 8: Fast Startup puts data at risk - The H Open: News and Features
Grub 2 efi has to be installed within the EFI partition …
I’ve installed 12.3 RC2 with UEFI. That went pretty well. As another responder says, you will actually be using grub2-efi.
I did use a separate disk for opensuse.
After I had finished the install, a reboot took me to the grub menu. The only entries on the grub menu were for booting opensuse. There was no Windows choice.
It seems that os-prober is not currently working with UEFI. This seems to be a work in progress.
I could still get to Windows, but I had to choose that at the BIOS prompt (on my box, F12 while booting gets a prompt). I’m currently looking at another discussion thread on this problem, so that I can come up with a manual change to the grub menu.
o/s prober has worked fine for me and automatically added a windows boot entry to the grub2-efi menu. might be worth going into yast and checking the bootloader section to see if you have a tick in the ‘foreign system’ box
Yes, that box is checked. But it is not finding Windows 8.
Well the manual way to add an entry is:
open a terminal window and switch to root
then run:
os-prober
my entry is:
opensuse:/home/garry # os-prober No volume groups found
/dev/sda2@/EFI/Microsoft/Boot/bootmgfw.efi:Windows Boot Manager:Windows:efi
then run:
opensuse:/home/garry # blkid/dev/sda1: UUID="9AD85337D85310BD" TYPE="ntfs"
/dev/sda4: UUID="58A7-C6C4" TYPE="vfat"
/dev/sda2: UUID="6453-92F3" TYPE="vfat"
/dev/sda5: LABEL="System" UUID="A2F61C7DF61C53BF" TYPE="ntfs"
/dev/sda6: LABEL="DATA" UUID="DFA8-AD5C" TYPE="vfat"
/dev/sda7: LABEL="Videos" UUID="1836E0A936E08958" TYPE="ntfs"
/dev/sda8: LABEL="CONFIG" UUID="DFF1-8CAD" TYPE="vfat"

/dev/sda10: UUID="b5b1749a-eb50-4cdc-83cd-fc575cb9de51" TYPE="swap"
/dev/sda11: UUID="1a1d72af-8649-48a8-b29f-b0ba150cfcec" TYPE="ext4"
The first bit tells me that my EFI bootloader is on sda2 and the secound bit tells me that the magic number is 6453-92F3.
The code to add to the bootloader (which is at root/boot/grub2-efi/grub.cfg) is:
menuentry 'Windows Boot Manager (on /dev/sda2)' --class windows --class os $menuentry_id_option 'osprober-efi-6453-92F3' { insmod part_gpt
insmod fat
set root='hd0,gpt2'
if x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root --hint-bios=hd0,gpt2 --hint-efi=hd0,gpt2 --hint-baremetal=ahci0,gpt2 6453-92F3
else
search --no-floppy --fs-uuid --set=root 6453-92F3
fi
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
}
As you will see you need to add your own magic number from following the first steps. Just for completeness I have shown the whole of my grub.cfg file below:

Must add that you use the steps at your own risk and if you make a mistake it can bugger up your system.
That gives no output.
However, if I first mount “/dev/sda1” (the efi partition from the windows drive), then os-prober provides output. So, with that partition still mounted, I ran “grub2-mkconfig” and it automatically generated an entry.
I haven’t tested it yet. I’ll do that on the next reboot.
did it work for you?
Yes, it worked.
Thanks.
that seem ok if linux and windows don’t use same hd and linux partitions are not installed on fat
Is it still the case with 12.3 final? If yes, you should open bug report.
It is working properly with 12.3 final (thanks for fixing it).
