I just bought an Asus computer with Windows 8 on it, and I'd like to install Ubuntu 13.04 alongside it. To begin with, I went in to disk management to shrink the main OS partition to make room for Ubuntu. When I got there, though, I saw an interesting arrangement.

Original partition scheme

OK, weird. Two recovery partitions, a system partition, and the OS partition. Fine, whatever. I went ahead and shrank the OS partition by as much as I could, 346,229 MB.

Partition scheme with shrunken OS partition

I then booted Ubuntu from a live USB and proceeded to install. I chose to set up partitions manually, putting a 1024 MB swap partition and the remaining size / partition in the freed up space. I pressed the install button to accept that configuration and install, but I got this error:

Error about boot code space

What do I need to do here? I thought among all those partitions one of them would already be the right type to hold that code. Also, if I choose the Ubuntu installer's default "install alongside windows", will this be set up correctly automatically?

Basically, your computer uses UEFI, and so a GPT partitioning table. GPT has no MBR to install GRUB into, so a partition has to exist for GRUB to be installed in instead.

Any recommendations as to where to put this partition? Does it need to be at the beginning of the drive? – D. Strout Jun 11 '13 at 11:40
I don't think so, but I may be wrong. As far as I know, it only has to be set as a bios_grub boot partition. – Autumnal Jun 11 '13 at 13:09
