I was trying to install Ubuntu 14 (64-bit) on a Aspire V5-531, preinstalled Win 8. In the bios I can flag:
boot mode UEFI, secure boot DISABLE
- in this case the neither installation USB card nor cd rom start
boot mode in Legacy Mode
- I can install Ubuntu 14, but grub doesn't work (yes, I used boot repair, but it doesen't work properly).
