There is much variation in hardware, but I was able to boot to an Ubuntu 14.04 live USB in UEFI / Secure Boot mode by doing the following: 1) Download the Ubuntu distro you want. It must be the 64 bit version. 2) Install the distro to USB stick using PendriveLinux.com's Universal USB Installer. 3) Power off the PC, insert the USB stick, and power on. 4) ...

Just a note: This is a Windows 8.* error, not an Ubuntu one, so it's better suited to a Windows forum. The question has been asked and answered here, so see if the answers on that forum resolve it for you.

Enabling BIOS/CSM/legacy support was a mistake. You now have Windows installed in EFI mode and Linux installed in BIOS mode. Most computers make it difficult to switch from one boot mode to the other, so such mixed-mode installations are difficult to manage. To fix it, install an EFI boot loader for Linux. As detailed on the page to which I've just linked, ...

It looks to me as if your X installation is running at too low of a resolution. Try this for diagnostics (and maybe to fix it): Open System Settings. Select Displays. Look at the value next to Resolution. Ideally, it will match the maximum resolution of your monitor. If it is, then something else is the cause; but if it's ridiculously low, that confirms my ...

To install Ubuntu alongside Windows 8 (with UEFI, GPT support or not) is a simple or not so simple task, depending on your computer's specifications. Many things have been said in this answers and some of them are obsolete, as Hellreaver noticed. Because every new question about this topic is redirected here, I feel obligated to respond. Now I am not a ...

Here are the key steps and information bits to get an HP laptop to dual boot between Windows 8/8.1 and Ubuntu 14.04.02. This laptop is a pretty modern Pavilion g7-2215dx. The BIOS of this laptop (and probably most modern HP laptops) has a UEFI boot menu that you can access by pressing ESC and then F9 when that menu shows up. This menu DOES PROPERLY WORK ...

Make a bootable USB-stick To create a bootable USB drive the tool that I advocate using is the Universal USB Installer from www.pendrivelinux.com. Partition Windows takes up the whole of the drive when it is first installed. In order to install Ubuntu you will need to make space for it. Press the "super key" (Windows key) on your keyboard and click the ...

I ended up solving this issue. I found out that even though the netbook was a newer model it was actually 32 bit. Therefore none of the 64 bit disk images would boot because they only contained 64 bit EFI drivers. I ended up... Downloading a 32 bit version of Linux Mint (which didn't have EFI support). I took the EFI folder from Gparted boot disk (which ...

Add this to 40_custom. gksudo gedit /etc/grub.d/40_custom sudo update-grub menuentry "Windows 8 UEFI" { insmod part_gpt insmod fat insmod search_fs_uuid insmod chain set root='(hd0,gpt2)' search --fs-uuid --no-floppy --set=root C0A6-125C chainloader (${root})/efi/Microsoft/Boot/bootmgfw.efi }

Firstly, it's important to get familiar with their app database, AppDB, this has a lot of information on how well a program runs in Wine (because there's no guarantee it'll work well) and what tweaks you might need to make to get it to run well. Secondly, if you find all that too complicated then you might want to try PlayOnLinux which will usually apply ...

A less radical fix Most computers enable you to enter the firmware setup utility, or at least get a boot manager menu, by hitting a function key (or sometimes Esc, Del, or something else) in the first few seconds after you power on the machine. Unfortunately, there's no standardization in what key does what, so if you don't see a prompt, you may have to ...

Although the specific instructions totally depend on your situation, partitioning etc. You should insert Windows 8 disc and replace Windows 7 (if you want that removed of course), simply format Windows 7 partition and install Windows 8. After doing so, your GRUB bootloader will be inaccessible, you should insert and boot an Ubuntu LiveCD and fix GRUB (using ...

You were right, the only remains of your Windows installation is the (U)EFI partition at the beginning of the disk (vfat). The other two partitions are Ubuntu (ext4) and a swap partition. You can see it here: Partition Start Sector End Sector # of Sectors System /dev/sda1 2,048 1,050,623 1,048,576 EFI System partition /dev/sda2 ...
