Yes, I have read, many times, "Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported)," and I have read the "UEFI" piece with the subtitle "Installing Ubuntu Quickly and Easily via Trial and Error." I have learned much from these pieces, but I'm still too much of a newbie to make it all work.
I have an HP15 Notebook with Windows 8.1 (64 bit) pre-installed. The chip is Intel Pentium CPU N3520 @ 2.16 GHz. Ram is 4GB. I wish to keep Windows 8.1 and have Ubuntu 14.04 dual boot with it.
The steps I've taken:
I changed the boot order in BIOS to enable booting to the USB.
I have Ubuntu on a USB, and I have toured it on that device. When I tried to install Ubuntu on the HD, I did not get the option of installing it along with Windows.
I turned off fast startup in Win8.
I disalbed hibernation in Win8.
In Win8 Disk Management I noticed that the partitions are these: 400 MB (Recovery Partition) 260 MB (EFI System Partition) 678.58 GB NTFS Windows (C:) 19.28 GB NTFS Recovery (D:) (OEM Partition)
In Win 8's Disk Management I created 300 GB unalloated partition by shrinking C:. The partition is GPT. The other partitions seem to be MS-DOS. Based on my understanding of the above articles, I leave UEFI enabled/installed, and I leave Secure Boot enabled.
On this machine ESC F10 gets one into BIOS. (ESC F2 gets one into UEFI.)
8 Booted up in the USB, using the try ubuntu without installing.
Set up internet connection.
tried to install Ubuntu on HD. Did not get the option to install alongside Windows.
At this point I guess I'm supposed to use the "something else" option, but unless it takes me through step-by-step, I'm afraid of screwing things up.
Here is what the BIOS currently has: Legacy Support is disabled Secure Boot is enabled UEFI boot order is USB Diskette then OS Boot Manager, then other options
(Many years ago I did this with MEPIS and had no trouble (:-).)
