Ubuntu 14 / Win 8.1 Install Problem

Question

I'm trying to return to Ubuntu on a new(er) computer after I had to switch to Mint on my old machine due to performance issues. The new machine is an HP pavillion G4 w/ 4gp memory and a 500GB HD. I can successfully run from live usb, although it cannot mount any of the windows drives.

I read : Installing Ubuntu Alongside a Pre-Installed Windows with UEFI

where the author describes how to install Ubuntu when it doesn't recognize the Windows 8 partitions. I've done all the pre-requisites, and still Ubuntu installer doesn't recognize the windows partitions. So now I'm down to the "Something else" method, and I'm confused with the language in this part:

"You need to create at least 1 partition for the root system (Which shows as the symbol "/") and set it to Ext4, another for SWAP (Virtual Memory). The SWAP space can be as small as 128MB if you have a lot of ram or as high as 4GB. With this 2 partitions created based on the empty space you provided you should be ready to proceed. And one last one for the EFI part which should be around 100MB."

I get that I have to:

1. root, mounted at /, ext4, (of approx size 50GB)

2. swap, mounted at "swap", (of size approx 6GB or 1.5 x physical memory)

3. Home (optional)

My question is what is meant by the "And one last one for the EFI part...?" Does this mean another partition? if so, mount point etc.

Answer 1

EFI partition is usually the firs one, so you can create setup like this /dev/sda1 (~200MB) of filesystem FAT32 and mount point /boot/efi

Answer 2

if you use uefi bios , you need an efi partition , and your win8 have already created one , and this efi partition doesn't need to monut , when you install , you just choose this partition to install efi loader file in it , it does the same thing when you install mbr in one partition for legacy bios
