btrf file system was selected as root partitions (Live USB). produce the same bug report as Live DVD installation

[aimwin]

This is second time identical Grub installation EROR and termination of installation.

Both with Live DVD, which I report in about 1 hour ago.
This time I use Live USB, complete clean booted in to Desktop with no error.

Then I execute installation and choose btrf file system as root partition or install partition.

I think it is the btrf option that crash the installation.

Since I have reinstall (using Live DVD 12.04.1) to sda12 with ext4 with 100% perfect, test boot into new hard disk installation.

I will reinstall with Live USB with ext4 installation, and report back.

I used the same Ubuntu 12.04.1 Live USB stick, installed to the same partition sda12 with ext4 as file system.
No errors and result in 100% perfect Ubuntu 12.04.1 that I use to write this report.

The reboot to hard disk result in grub rescue prompt.

From
https://help.ubuntu.com/community/btrfs
............... You must install it to either the parent (sda rather than sda1; MBR/Reserved Sectors) 'OR' use a dedicated /boot partition as described in the forum post below.
When installing Ubuntu in one large btrfs-Partition without an extra boot-partition, take care to keep about 1 Mib space free at the beginning of the disk. When there is not this space, the installer fails at the end when trying to install Grub! ............

And

......long and involve good understanding of btrf. and how to........
That is not an easy normal installation of ext4... I just learn that today after reading many more info on how to btrf?

Can someone confirm the above issue.

That I am too naive to just select the btrf in replacement of ext4, during the normal installation.

Because if we want to use btrf we need to follow these instructions in
https://btrfs.wiki.kernel.org/index.php/Ubuntu_support

or it is another bug in the 12.04.1 installation programs?

is another instruction to install btrf.

I believe that the errors are normal result of the wrong way of installation of btrf file system.
