Thread: MAC Tripple Boot W7,Ubuntu 12.04 Grub Problem

problem: windows won't start.

background:
installed windows 7 bootcamp.
installed refit
created 2 partitions ubuntu+swap
installed ubuntu, grub partition sda2

ubuntu works fine.

@ refit screen have 3 options: macos / linux / windows
linux: nothing
windows: boots grub options boot ubuntu/ubuntu recovery/.../windows 7 (loader)

if hit windows 7 screen pops file: boot/bcd missing.
if start ubuntu , mount bootcamp partition can see file there.

tried far:
update-grub

dak@dak-macmini:~$ sudo update-grub
generating grub.cfg ...
found linux image: /boot/vmlinuz-3.2.0-32-generic-pae
found initrd image: /boot/initrd.img-3.2.0-32-generic-pae
found linux image: /boot/vmlinuz-3.2.0-29-generic-pae
found initrd image: /boot/initrd.img-3.2.0-29-generic-pae
found memtest86+ image: /boot/memtest86+.bin
found mac os x on /dev/sda2
found windows 7 (loader) on /dev/sda5
done

windowsrecovery windows 7 cd:
chckdsk
bootrec.exe /fixmbr: works
bootrec.exe /fixboot: says there no windows partitions


partitiontable:

dev/sda1: efi (210mb fat)
dev/sda2: hfs+(32gb) - mac os x
dev/sda3: ext4(14gb) - ubuntu
dev/sda4: linux swap(4,3gb) - ubuntu swap
dev/sda5: ntfs (78gb) - windows

so seems partition doesn't mounted when select windows grub ?

set "some" arguments manually grub windows started.

setparams 'windows...'
insmod part-gpt
insmod ntfs
set root = '(hd0,gpt5)'
search --nofloppy --fs-uuid --set=root 1234...

edit:
remebered changed mbr before ahci in windows 7 working on mac mini:

mac mini 1.1 updated firmware 2.1 , added ahci tutorial:

seems confused: gpt/mbr/uefi

need know if bios or uefi machine
need know how bios set: bios or uefi
need know if have installed grub mbr or gpt
