I'm trying to install Ubuntu 14.04 on my Dell XPS 15 9530, and I have a few questions.
What I've done so far:
- Deactivated acceleration in Intel Rapid Storage Technology
- Disabled Intel Rapid Start Technology
- Turned off Fast Start Up option in Windows Power Options
I've followed this link for the installation, put Ubuntu 14.04 on a Live USB Stick, shrinked the Windows partition and tried to install it from there.
My problem is that to boot from the USB stick, I have to turn on the "Load Legacy Option Rom" in the UEFI, otherwise Windows doesn't show me the option to boot from it. (I use shift click on restart on my Windows 8.1, then choose the boot from device option).
Now, I've read that enabling the Load Legacy Option Rom is not a very good way to do this, since, as far as I understand it, you then use 2 systems at the same time (i.e. Uefi for Windows, and the old Bios for Ubuntu and you need to switch back and forth between them).
So is there a way to boot from my USB stick while disabling the Load Legacy Option Rom?
I've read here that you need to turn off Intel Smart Response and switch to AHCI. Is this safe? Because I get a warning that I'd have to re-install Windows if i'd do so.
What I'd ultimately want to achieve is that at start up, I can choose what OS to boot with.
Hope someone can help
