I'm using an Acer Aspire v5-471 PG Touch.
Intel (R) Core(TM) i5-3337U CPU @ 1.80GHz
System Bios V2.13
NVIDIA GeForce GT
Windows 8 pre-installed
I installed Ubuntu 13.10 on it and after running boot repair and restarting the computer this is what appeared on my grub menu:
Ubuntu Advanced Options for Ubuntu Windows UEFI bkpbootmgfw.efi Windows Boot UEFI loader EFI/OEM/Boot/bootmgfw.efi Windows BootManager (UEFI on /dev/sda2) System setup
I tried all the options but it will only display
Error: cannot load image.
Booting using Legacy Bios and disabling secure boot, will show a screen
Operating System not found and some gray text on a black screen about some patent about Intel??(not sure).
And another thing, when I use Ubuntu I can't adjust the brightness, my laptop overheats and consumes too much power. The battery gets drained after an hour. When I used windows 8 before I can use it up to 3 hours.
So to sum it up I need help on 1) Booting back to Windows 2) Repair overheating and power problems.
I just started using Ubuntu so I hope you could explain it simply.
