Unhappy How to Dual boot windows 8.1 and elementary OS Luna/Freya?


Ok I am sort of totally freaking out right now.
I just bought an Asus x200ma with windows 8.1 and UEFI 4gb memory and an intel 1.69 ghz core(ithink). MY whole goal was to dual boot elementary OS or Ubuntu (preferably elementary) alongside windows 8.1. So I have spent the last 4 days on every Linux help chat I can find and I still haven't found an answer. I don't mind waiting until Freya comes out if that's what it takes. I just need info.

So this Is what I have tried so far...
I started in windows by making a 20gb recovery drive. and then allocated roughly 195 Gb to unallocated. then i turned off secure boot and turned on launch CSM.
Then i plugged in my usb 2.0 liveboot elementary OS Luna drive that i made. That worked ok and started the install process.
I clicked install, and then started the allocation process. i gave 4gb of storage to swap partition and then gave the rest to ext4 jouraling system mount point / . After that i set the ext 4 partiton or partiton 7 and set that as the boot place, i then clicked install and finished that process. after words i restarted removed the boot drive and it booted to windows. i then opened UEFI advanced boot settings and there was nothing under boot order except windows. When i started windows it showed that there was a primary swap partition and a primary partition of roughly 191 gb. after asking everywhere with no luck i started over a few times rying different things but in the end undid the allocation and gave all 500 gb to windows. i still want to dual boot but i am waiting for some solid instructions.

Any help as soon as possible would be very greatly appriciated. Thanks so much in advance!

p.s. if there are any questions that you have ask and i will try to tell you.

See the HOWTOS in http://www.tldp.org for dual/multi booting.

If your computer came with windows 8 pre-installed, it was probably installed in UEFI mode which would mean you would have to install Elementary in UEFI mode also. There is generally a vfat partition near the front of the disk which contains both the windows and Elementary efi files. I don't use UEFI myself so can't give any more specifics but you should have had that option during the install.

Elementary is based on Ubuntu, have you tried the Ubuntu forums?

I believe you need to boot a 64bit live usb with both secure boot and CSM disable for the installation to work

I tried ask Ubuntu they said since it was elementary OS it was "off topic" so I came here.

Some say to disable CSM some say to enable CSM why should I enable.
I downloaded the 64 bit torrent and made a live USB so... Are you saying there is a version specifically made for UEFI?

Veerain I don't understand the links you posted. They lead to websites that don't deal at all with my question. Please explain.

Consider running a free virtual machine as a different way to go.

I don't think there is a separate version for UEFI. With most of the major Ubuntu install media, there is an option when you boot the medium to select to boot either UEFI/GPT or MBR BIOS. May not have that with Elementary.

They have a separate section for "Other OS' at the link below. I've seen posts there regarding Elementary as well as a number of other Ubuntu derivatives.

Here are two links describing it, haven't use it myself.

@OP: if you installed Elementary in non-EFI mode (CSM enabled), then it will not boot up in EFI-mode.

You could get it to boot up by enabling CSM again, but this would mean Windows will not boot up.

I have "converted" non-EFI booting distributions to an EFI-mode install by copying the /boot partition over to the Windows-generated EFI system partition and changing the fstab to reflect this, installing a minimal (non X) Arch system (also sharing the same /boot partition) to control the booting process and using gummiboot to manage all the boot entries for the separate operating systems.

It works, but it's a bit of a faff...

I'm not an arch Linux user. I know very little about code. How do I use gummiboot? Is there an instruction page?

I figured out my problem! Turns out it doesn't really work to dual boot windows 8 UEFI with elementary OS Luna. But I did dual boot Ubuntu. I figured out how to dual boot it with Ubuntu. My problem was I had 3 primary partitions to start with, and Luna doesn't let you chose logical partitions instead of Primary. Thankfully elementary OS Freya is almost out which will work.

Here is the only instruction page I found on dual booting UEFI that worked: http://www.instructables.com/id/Dual...indows-8-UEFI/
