Today I received my new convertible device, a HP Pavilion x2 10-n015n, which came preinstalled with Windows 8.1 32bit.
As I'd like to - at least testwise - install Ubuntu GNOME on it, I created a bootable USB stick with the 14.04 LTS ISO of Ubuntu GNOME. However, when trying to boot it, I only receive the following message:
The selected boot device failed. Press <Enter> to continue.
What I've tried so far:
- Disable fast boot in Windows
- Disable Secure Boot in the BIOS settings
- Searched for an option to enable Legacy booting, but there is none
- Used both UnetBootin and Ubuntu's Startup Disk Creator
- Used two different USB drives
- Tried both the 32bit and 64bit image of Ubuntu GNOME
- Verified checksums (although it shouldn't be necessary using BitTorrent)
- Also tried the "normal" Ubuntu (also 14.04), in case Ubuntu GNOME didn't yet support UEFI.
- On my main computer (no UEFI, no Windows), the live system booted without problems each time.
- Tried creating the bootstick using Rufus (both GPT and MBR parttables, both ISO and dd mode), as suggested by Raphael.
None of these helped me:
- “selected bootable device failed” error dual boot ubuntu alongside windows8.1
- Dual Booting in HP Laptop "Selected boot device failed to boot" Error
Do you have any idea why the USB won't boot or what can be done about it?
