EFI partition should be mounted on /boot/efi, not /boot. This is where GRUB puts EFI loader. /boot is for kernel image and initrd. I am not convinced you are actually booting in EFI mode... Check /sys/firmware/efi exists. Not sure what Windows wants from you, but try the following: mkdir /boot.NEW, move everything from /boot to /boot.NEW umount /boot ...

You can't have custom images for a bios boot screen.... The most you can do is enable the boot logo or disable it but customizing would never work. Also most mediums of storage wouldn't be available to the bios before post so no way to even store an image for this..

You change your system to use legacy boot mode instead of standard boot mode. When this is enabled, the system will boot up just like earlier versions of Windows, which causes the OS list to show up just after the system turns on (on dual-boot PCs) and adds the ability to press and hold F8 to access advanced system options upon turning it on (on single-boot ...

From Wikipedia: The Unified Extensible Firmware Interface (UEFI) (pronounced as an initialism U-E-F-I or like "unify" without the n)* *Various pronunciations have existed for UEFI; according to the UK PC Pro Magazine, the following pronunciations are in use: "weffy" (PC Pro), "U-E-F-I" (Microsoft), "you-fee", and "you-ef-fee". It is also mentioned ...

Thanks guys for your help! As you've stated, I didn't install Windows 8 properly the first time and was missing the EFI partition. The reason is that I didn't use a UEFI bootable USB drive. I followed this tutorial to create the right bootable USB drive: http://www.eightforums.com/tutorials/15458-uefi-bootable-usb-flash-drive-create-windows.html

Problem fixed. To fix problem you must fix partition with Fixparts utility (fixparts \.\physicaldriveХ where X is disk number).

i have found the answer!! do not ask me how it worked i do not know, i had struggled for hours and hours, to no avail. i had been using a linux mint 17 cinnamon live boot usb to partition the HDD, as i was hoping it would be a tad better than the quite awful drive selection options to format and such on the windows 7 install disk, but still getting the got ...

try boot-repair-disk. It's a handy soft for this kind of issue. (there is an option to restore the mbr if you want to keep only windows 8).

Not sure if you decided to buy this motherboard, but for anyone thinking about it, I purchased board with A G3258 cpu on 14th September (same Haswell family) and the board shipped with bios 805 or 806, booted fine with cpu and was able to flash bios to 2001, although not done any over clocking on it yet.

Alright, I stumbled upon the perfect article on AskUbuntu.com. SecureBoot doesn't show up because my computer doesn't have it. To figure out if you have SecureBoot or not, run Windows PowerShell as Administrator, then type: Confirm-SecureBootUEFI It will return true, false, or "Cmdlet not supported on this platform". Mine returned with the latter, and ...

Yes, if the "BIOS emulation" aka "Compatibility support module" is present, then it has to start in real mode because that's what all BIOS-format bootloaders expect (even if many of them immediately upgrade to protected mode). Hence the 'compatibility' in its name. (This of course only applies when booting from the MBR boot sector. All .efi format ...

Windows does create an EFI/BIOS partition by itself. The only thing that you might/should be worried about is the MBR. Make sure to do some research about that on Microsoft's documentation on Windows. Otherwise, fixing it afterwards isn't that much of a deal and might even be doable from Ubuntu. As long as you can boot into Ubuntu before installing Windows, ...

The only way to do it is to have full format of your HD. You can't have GPT and MBR per partition. It is only PER disk.

So, as i suggested, you should boot in with the Hiren Boot cd somewhere you can do it successfully. I suppose it has a builtin grub in it, so try grub2-install --target=x86_64-efi --> or i don't know what instruction set your laptop has, but read grub's man page for help (first make sure, you have a boot directory, if not, then make one:)) After this has ...

Chipset initialization and such other extremely low-level hardware specific code has always been mostly closed-source. BIOS/UEFI does not change the fact that details of memeory controller initialization etc. are rarely disclosed by board vendors. To have a true open-source board, you'll have to look for open-source hardware, some vendor who exposes all the ...

Which ISO are you trying to boot in UEFI? Check if it has a file /boot/bootx64.efi or the like. If it does, then just follow @Snayob's comment. A non-UEFI bootable ISO CAN be made into a UEFI bootable USB stick if it has the UEFI bootloader as a file. The presence of a file like this cannot however boot the CD/DVD itself because CD/DVD booting requires more ...

So far I found that on the Acer website there are updates I can download for my BIOS - and one of them mentions Windows 8 - so perhaps that would be the answer. Oddly enough as well, my laptop was able to recognise Windows 7 on my old USB but not on the new one (which was the one I mentioned in the initial question). I won't mark the question as solved ...

The closest I can think to what you describe would be something like having Ubuntu on a USB drive and having the internal hard drive take precedence in the boot order. It would boot normally unless you hit the key (typically F12 or Esc) at startup to select the boot device, in which case, you could select the drive containing Ubuntu.

There is the possibility to use "fdisk" for non destructive MBR to GPT conversion of disk style - see http://www.rodsbooks.com/gdisk/mbr2gpt.html Also reinstallation of Windows would not be necessary as boot parameters (and boot programs) can be changed from BIOS(MBR) to UEFI(GPT) style (I have not done this in practice and cannot guarantee 100% that it ...
