[Bug 1267093] Re: Manual Partitioning unable to set Bootable flag to on.

[Alan]

As far as I can see, the main problem is that it doesn't allow you to
turn the "Bootable Flag to On".

This also causes the grub installation to fail.

I have also tried "Automatically Partition the Free Space" when doing "Create Partition"
This gives each 3TB drive:
        1.0 MB       FREE SPACE
#1   1.0 MB  K  biosgrub
#2   3.0 TB   f   ext4               /
#3   8.5 GB  f    swap             swap
   466.4  kB        FREE SPACE

I then go to the RAID Configuration and go "Create MD" and add the three of each drive to the array (biosgrub, ext4, swap)
but when I get to the end of this (finished teh RAID COnfiguration) and get back to the partitioner and try to exit and write all to disk, I get an error message:
"No root file system is defined.
Please correct this from the partitioning menu"

Title:
  Manual Partitioning unable to set Bootable flag to on.

Status in “debian-installer” package in Ubuntu:
  New

Bug description:
  I have downloaded the Ubuntu 12.04.3 LTS 64-bit Server Installer today
  and burned it to disk.

  I am trying to setup a software RAID 1 array because the Installer doesn't recognise my Intel hardware RAID1 array 
  (brand new Gigabyte Motherboard.)

  trying to follow many tutorials and the instructions of experts in the
  Ubuntu Forums made me realise that the Installer has been changed
  since all of the tutorials were written. A lot of options are
  different or missing, or indeed added that weren't there originally.

  When manually Partitioning,
  When you create a new Partition, you are no longer given the choice of Primary or Logical, and there is now no way to set the Bootable Flag to "on"

  This of course means the instal fails.

  I believe there is no other way to do a software RAID1 instal than by
  manually partitioning so that means you can now no longer do a
  software RAID 1 instal of 12.04.3 LTS

  I have discovered at least one other who has tried with a "new installer" and is having this trouble,
  In the comments of this post:
  http://www.itfromscratch.com/install-ubuntu-server-12-04-with-encrypted-lvm-on-raid1/3/

  I have also read other people complaining about RAID1 setup failures
  and many different ways of trying to manually instal grub after the
  failed instal.

  I think this should be looked into.
  I can't find anywhere to report it as a bug.

  Anybody who could shed any light on this would be much appreciated.
