linux - How to run bootable media on Asus S550CM ultrabook while preserving existing pre-installed Windows 8?

    I recently bought an Asus S550CM ultrabook with Windows 8 pre-installed on it. However, I need to also install Fedora 19 beta on the same machine simultaneously as a dual boot option for my work, which involves quite a bit of cross-platform testing.

    I had setup & used similar dual boot configuration for my laptops earlier when I had Windows Vista and then Windows 7 with various iterations of Fedora OS, without any trouble.

    This time I'm unable to set up a dual boot configuration with Windows 8 and Fedora as I'm unable to boot from any kind of bootable media (USB/DVD) even after I set up Boot device priority to access USB first, then DVD, and then the Windows Image and finally I disabled Secure Boot. I'm however, unable to locate any options for enabling Legacy Boot on the BIOS. The BIOS shows my USB device's name as [UEFI:Sandisk16GBVolume].

    I want make a backup/recovery disk for my existing Windows 8 and then set up a dual boot configuration without erasing the existing installation, to be able to resume my work on my day job. I didn't receive any backup/recovery disk with the ultrabook, hence re-installing Windows is not an option for me.

    In this situation, how can I install Fedora on my Asus S550CM ultrabook while keeping the existing pre-installed Windows 8 intact?

    Hit F2 before the Asus logo appears during boot. Find the following two settings and set them accordingly:

    • Security > Secure Boot Control: Disabled
    • Boot > Launch CSM: Enabled

    Select 'Save & Exit' from the menu. Upon restarting, hit F2 again to enter the BIOS and set your boot priorities.

    At the end of the day simply hitting the 'ESC' Key during boot did the trick!! Steps:-

    1. Once the laptop is switched on, press the 'ESC' Key.
    2. Select Boot media.
    3. Do whatever you want to do!

    That's it!! Done!! :D

    partitioning - Installing/dual-booting Fedora 17 on existing Windows 7 HDD
  • Moose4

    I have a 64-bit Windows 7 install as the only partition on a 1 TB HDD, with about 350 GB free. I would like to install Fedora 17 as a dual-boot option on this system and give it about 100 GB to play with.

    If in the Fedora install utility I choose to shrink the Windows 7 partition by 100 GB to give it space, will that cause me to lose my existing Windows 7 data? And how do I go about setting up dual-boot (with Windows 7 as the default)?

    Generally, no. However, you should always have a backup of your data so that you can restore it incase something goes wrong.

    And how do I go about setting up dual-boot (with Windows 7 as the default)?

    Just follow the install Wizard, there's nothing special to be done to set up dual boot.
