[Bug 996617] Re: New install on laptop installed incorrect version of Grub (Grub-efi)

[John Rose]

I converted my hard disk's partition table to gpt from mbr, using instructions at:
http://falstaff.agner.ch/2012/11/20/convert-mbr-partition-table-to-gpt-ubuntu/
I rebooted successfully & confirmed that the conversion was OK using gparted.

My BIOS is EFI capable so I intend to clean install 64 bit 12.0.2. I
currently have 32 bit 12.04.2 but it's not EFI capable. So I tried usng
a USB stick containing 12.04.2 64 bit. The BIOS showed it as EFI
capable. So I booted from it. That was OK. So I invoked the 'Install
Ubuntu' option using its icon. I went into the partitioning and found
that no efi partition (at /boot/efi) would be created whether I was to
erase the disk or use the default partitions specified initially in the
Advanced partitioning option.

Thus, it seems to me that 64 bit 12.04.2 will not be installed (on a BIOS capable of it) unless gparted is used before the installation is started. This seems to contradict 
https://help.ubuntu.com/community/UEFI
where it states "nothing special is required if you use the automatic installer of Ubuntu ("Install Ubuntu alongside others" or "Erase the disk and install Ubuntu"). ".
