Here are a set of notes I made for myself because I did this often
enough I didn't want to forget. I hope this helps.

New procedure for using Ubuntu Desktop installer (until they fix it)
--------------------------------------------------------------------
1) Launch UEFI setup at startup:
* Disable Legacy BIOS
* Turn on RAID & SMART
2) Boot Ubuntu CD:
1) Pick "Try Ubuntu" & edit kernel command line.
2) Add "nodmraid" to kernel line to prevent dmraid from
assembling the disks.
3) Hit F10 to start session.
3) Start 2 terminals & increase scrolling buffer.
4) sudo to root in one of the windows.
5) Do the following before starting installation:
1) apt-get purge dmraid
2) apt-get install mdadm
3) mdadm --assemble --scan --verbose
6) Partition the raid drive:
1) gdisk /dev/md126
1G EFI partition (EF00)
1T EXT4 partition (FD00) <-- change md126p2 to type FD00
128G swap partition (8200)
600G NTFS partition (0700)
7) Do the following before starting installation:
1) apt-get install grub-efi-amd64
2) apt-get update
apt-get upgrade
8) Run installer until it fails on bootloader.
9) Mount & chroot raid disk:
1) mkdir /target (if not still mounted)
2) mount /dev/md126p2 /target
3) mount /dev/md126p1 /target/boot/efi
4) for i in /dev /dev/pts /proc /sys /run; do mount -B $i
/target$i; done
5) chroot /target
10) Do the following again on the chroot volume:
apt-get purge dmraid
apt-get install mdadm
apt-get install grub-efi-amd64
apt-get update
apt-get upgrade
11) Run grub-install to fix the bootloader:
* grub-install --boot-directory=/boot --bootloader-id=ubuntu
--target=x86_64-efi --efi-directory=/boot/efi --recheck
[--verbose|--debug] /dev/md126
12) Unmount the raid disk:
* for i in /dev /dev/pts /proc /sys /run; do umount /target$i;
done
* umount /target/boot/efi
umount /target/boot
13) Find all the places that may try to stop mdadm/mdmon from starting &
disable them:
* find /etc -name "*" -type f -exec grep 'nomdmonisw' {} \; -print
* find /lib -name "*" -type f -exec grep 'nomdmonisw' {} \; -print
* find /usr -name "*" -type f -exec grep 'nomdmonisw' {} \; -print
* Comment out dmraid2mdadm.cfg at /etc/default/grub.d/
14) Fix up the mdadm configuration:
* cp /lib/udev/rules.d/63-md-raid-arrays.rules /etc/udev/rules.d/
* cp /lib/udev/rules.d/64-md-raid-assembly.rules /etc/udev/rules.d/
* cp /usr/share/initramfs-tools/hooks/mdadm /etc/initramfs-tools/hooks/
* cp /usr/share/initramfs-tools/scripts/mdadm-functions
/etc/initramfs-tools/scripts/
* Edit rules if need be.
* See mdadm.patch file from bug# 1320402 & fix up files.
* Create /etc/initramfs-tools/conf.d/mdadm:
## mdadm boot_degraded configuration
##
BOOT_DEGRADED=true
* Create /boot/efi/EFI/ubuntu/grub.cfg:
search.fs_uuid 9b5a6959-7df1-4455-a643-d369487d24aa root
set prefix=($root)'/@/boot/grub'
configfile $prefix/grub.cfg
* update-grub
15) reboot
