I have purchased an Asus K95V laptop with pre-installed Windows 8 (OEM) on the hard disk one month ago. I have also purchased a new 250GB SSD disk (not yet put into the laptop).
The last 5 years I have used Ubuntu as the only OS on my old computer (that broke down 1 month ago with Ubuntu 12.04). The problem running Ubuntu only has been that a few programs does not run in Ubuntu, and then I have annoyed my wife using her Windows 7 laptop.
I will now install Ubuntu 12.10 as the primary operative system on the new laptop, but I also hope to keep the Windows 8 (OEM) as a secondary OS when occasionally needed. I have read about dual boot, UEFI/EFI and secure boot for three weeks on this forum and elsewhere and I am very confused since various boot managers and boot loaders are mentioned, and it seems to be almost an unlimited number of different ways to do it.
The hardware:
Asus laptop K95V (intel Core i7, nvidia geforce GT 635M, 8GB RAM, 1 TB harddisk) with pre-installed Windows 8 (OEM). The "BIOS" is of type Aptio Setup Utility version 2.15.1228, BIOS version 225. The Windows 8 partition C:\ (sda3) is successfully shrinked to 80GB one month ago following the description by parminides, #6 (http://ubuntuforums.org/showthread.php?t=2087466) (thank you!). The SSD is brand new (never used) of type “Samsung SSD 840 Series 250GB 2.5" OEM” that will be mounted into the laptop when I start installing Ubuntu.
Back-ups already done:
I have made a Windows 8 recovery DVD following the following procedure (http://www.ghacks.net/2012/11/01/how-to-create-a-windows-8-system-repair-disc/).
I have backed up the personal files in Windows 8 partition (sda3)
Back-ups not done:
The EFI partitions (sda1). I tried mountvol z: /s, but xcopy did not work due to insufficient user access.
Plan:
1) Keep the original the EFI partition (sda1), the original 600MB recovery partitions (sda2) and the shrinked 80GB Windows 8 partition (sda3) at the beginning of the hard disk. Further I also plan to keep the original 20GB recovery partition (sda7) at the end of the hard disk.
2) Install Ubuntu 12.10 with the “LiveDVD of the Ubuntu-Secure-Remix 64bit” on the system alongside Windows 8 following the steps in Ubuntu UEFI (https://help.ubuntu.com/community/UEFI) using the 12.10 Ubuntu-Secure-Remix 64bit DVD. Here I have already identified that the DVD boots in EFI mode trying the Ubuntu LiveDVD.
3) Make new partitions in the remaining hard disk space between sda3 and sda7. These are: sda4: empty spare 5GB ext4; sda5: Windows/Ubuntu shared partition 20GB NTFS; and sda6: Ubuntu /home1 800GB ext4.
4) Make new partitions in the new SSD: sdb1: spare 300MB FAT32; sbd2: spare 1GB ext4; sdb3: Ubuntu swap 16GB; sdb4: spare 5GB ext4; sdb5: Ubuntu root / 30GB ext4; sdb6: Ubuntu /home0 180GB ext4; and sdb7: spare 5GB ext4.
5) Put the Ubuntu 12.10 system into the SSD partitions: /root in sdb5, swap in sdb3 and /home0 in sdb6. Put the Ubuntu /home1 into the hard disk partition sda6.
6) Hopefully the Ubuntu boot files go into the existing EFI partition (sda1) and the root / partition (sdb5).
7) Eventually use Boot-Repair if/when needed.
Question 1: on BIOS settings
a) Launch CSM = Enabled.
b) Launch PXE OpROM = Enabled
c) Intel anti theft technology = Disabled
d) Secure boot = Disabled
Are the above settings OK when I want to install Ubuntu 12.10 in dual boot system alongside Windows 8 in EFI mode?
Question 2: on BIOS settings, ref point 2 in UEFI (https://help.ubuntu.com/community/UEFI)
a) I cannot find QuickBoot/FastBoot in the BIOS (for disable).
b) I cannot find Intel Smart Response Technology (SRT) in the BIOS (for disable).
Does QuickBoot/FastBoot and Intel Smart Response Technology (SRT) have other names, or should I not worry about these settings as they may not be applicable for this laptop?
Question 3:
How can I back-up the EFI (sda1) partition before I start (convenient and free method preferred)?
Is it necessary to back-up the recovery partitions (more than 20GB of data in total) or the Windows 8 partition (40GB of data), since I have made a recovery DVD?
Question 4:
Is this plan feasible? I hope it will not cause problems to put the Ubuntu OS on the SSD while the EFI partition (sda1) is located on the hard disk with Windows 8.
Thanks for your help.
