Ubuntu 10.10 (AMD 64) installer on Intel "fake RAID" writes GRUB boot code to MBR, not to root of Linux partition, contrary to selected option.

10.10 reached end of life some time ago and is no longer supported. Are you able to reproduce this on 14.04 or 14.10?

Phillip,

Neat question.

The machine has gone through a few upgrade cycles now. I think it's on
13.10. No problem with the upgrades.

It's not a test rig. So, not practical to try a fresh installation, sorry.

I suggest either later versions lack the fault or the specific
configuration which it affects is far from popular.
