Unfortunately, Apple seems to delight in making changes to particular Mac models that require completely changing everything one needs to do to install anything but OS X on the computer. Chances are it's such model-specific issues that are causing you problems. You might have some luck with a Web search on "Ubuntu" and some variant of your model number. When ...

I had the same issue. I installed Windows 8 on a GPT formatted disk and when I tried to install Ubuntu 13.10 it didn't even recognize Windows existed. You must format your disk to the mbr format to have Ubuntu recognize windows. This is because the GPT partition format does not gel with Ubuntu that well though you can install it. Here's what I did that ...

I recommend adding Refit as it suggested. I have never found a workaround to using refit when dualbooting a macintosh computer. Install refit on your computer and restart the installation process. I recommend inserting the disk and then shutting down. Upon booting hold the option key and you should be able to select the ubuntu disk image. Install as usual ...

You already have Kubuntu installed on the laptop you want to upgrade? Or do you have Kubuntu on a different machine and would like to put another copy on your laptop? Do not install Kubuntu I686 on a 64bit machine. It will only allow you to use 4gig of ram. I'm going to guess you have more than that. The AMD64 part probably threw you off. They really ...

I think this might be because of UEFI. I did a quick search and found this, try it. http://scienceblogs.com/aardvarchaeology/2013/12/16/tech-note-how-to-install-linux-on-a-laptop-with-uefi/

As far as I know, GRUB2 doesn't boot Windows all by itself, it just calls the NTLDR (or Windows Loader in W8 and W8.1). Besides, AFAIK, GRUB2 is just a bootloader and not an OS installer. You should download (if that's what you did) another ISO, or ask in Microsoft Support for your missing Windows packages.

will it be like 12.04.04 or 13.10 where the screen just goes completely black? I think your premise is false here. 12.04.4 and 13.10 should work just fine on a computer with a UEFI motherboard (which pretty much all motherboards are now anyway). If you're having problems with 12.04.4 or 13.10, then the problem is not likely to be with Ubuntu but ...


1

The bricking problem has been bypassed with recent kernels, which 12.04.4 should provide. (You might want to wait 3 days until 14.04 LTS is released, though; it will have more up-to-date EFI support generally.)

Yes, it is possible to boot Windows 8 in UEFI mode, even if you installed it on a legacy partitioned disk (MS-DOS/MBR). Of course you would need a UEFI compatible GRUB installation on another GPT partitioned disk. In Windows, install a new boot configuration to volume C: by running the following command: bcdboot C:\Windows /s C: /f uefi When booted in ...

Is it really missing or just not the default anymore? This may just be a misconception, please take a look at the boot order in your firmware setup screen or run efibootmgr if you are in Ubuntu. Windows actually installed two bootloaders: the default UEFI bootloader for the drive in \EFI\boot\bootx64.efi, which – to my experience – will create a new entry ...

Solved I reinstalled in UEFI and now it boots into my os as it should. Thanks guys. The issue was from initially installing in legacy Bios by mistake. Noobie move I know. But I learned a Lil something along the way. :)

The problem is the BIOS. You will need to enter your bios. Disable UFEI boot and enable legacy support. In other words you need to disable secure boot. I had this same error on a brand new HP Pavilion out of the box; where I wiped windows 8 for a clean ubuntu 13.04 server. Let me know if you have any questions.

I have the Y510p with 755M/i7/8GB RAM and dual-booting Win 8.1/Ubuntu 13.10. I spent about 30 hours trying to get the Nvidia card working properly and finally I have uninstalled all drivers and I'm running only Intel card now. The only thing that worked properly for me was installing nvidia-331 nvidia-settings-331 and nvidia-prime and than purging bumblebee ...

If you want Ubuntu on the same disk as Windows 8.1, here are the steps to go through: 1) [Turn off Windows Fast Boot][1] 2) You need to shrink the main Windows 8.1 partition. This can be tricky, as Windows expects a certain partition scheme to be used. Let me show you a diagram: [(Windows RE Tools)(EFI System Partition)(Microsoft Reserved ...

Most computers let you disable Secure Boot without enabling BIOS/CSM/legacy-mode booting. Look for an option to enable you to do this. With Secure Boot off, you should be able to install Ubuntu in EFI mode; or you can use rEFInd, on a CD-R or USB flash drive, to boot Ubuntu in EFI mode. That done, installing the Debian package should enable you to choose ...

The main points are: EFI-mode booting can be faster. The difference can be several seconds, contrary to what K. Darien Freeheart wrote, but the difference also varies from one computer to another; on some computers, the speed benefit can be non-existent. The effect is felt mainly in the firmware initialization, not in the Linux boot process itself. An ...

In theory, UEFI boots faster, but we're talking fractions of a second in an already quick process. Practically, if you're only running Ubuntu then there shouldn't be major differences. The userland supports stuff like large partitions in either mode. Things can get troublesome in a dual-boot situation, especially with Windows since different versions have ...

I have the y510p. 12.04 was workable at best. Framerates were ok in glxgears and such. Bumblebee with the Nvidia and the Nouveau driver both worked, albeit fairly low framerates. The challenge at this stage of the game is the Nvidia linux support for the 755m card in the laptop.

Somewhere in your BIOS menu there must be some command to allow you to disable that PXE (network) boot. Either this or move PXE in boot menu - boot devices order to the last position after CD/DVD-ROM, HDD and USB.

There are many possible "black screen" causes. The post to which user68186 linked has many possible solutions, and I suspect that you haven't tried all of them.

It is vital for all systems running Windows 8 in UEFI mode to have fast boot and hibernated shutdown turned off, as well as fast boot in the UEFI. This keeps you from losing data on your Windows install. I feel like I keep giving this same answer over and over again, but c'est la vie: First off, you cannot run dual boot configuration with Windows 8 in ...

I'm afraid that your points 1-4 are all the exact opposite of what you should have done. Computers that come pre-installed with Windows 8 or 8.1 almost invariably boot in EFI mode. When installing Ubuntu for dual-booting with a computer that's already booting in EFI mode, it's almost always easiest and best to install Ubuntu in EFI mode. In the case of most ...

The third choice provided by Live Ubuntu Installer is to choose Something else instead of Install Ubuntu alonside Windows. It seems like the best choice for you since it will get you to the partition table for your hard disk where you can modify and format partitions and choose where exactly you want to install Ubuntu.

Take the hard drive out of your laptop. This should allow you to get into the UEFI. If that does not work, the instructions (take from the VAIO User Guide) to get into the UEFI are as follows: Press the ASSIST button while your VAIO computer is off. The VAIO Care Rescue Mode screen appears. Select Start BIOS setup. Enter a password if it has already been ...

I had similar problem with Dell XPS 13 but with Ubuntu 12.04 64 bit. While trying to boot from USB it was going in an infinite loop as you mentioned. I had Legacy boot option as default.

IMHO, the difference between a long-term support (LTS) release, which is what 14.04 is, and a non-LTS release, is more important than the possibility of improved EFI support in 14.04. This is very graphically illustrated here: As you can see, 13.10 will become unsupported this year (in July, to be precise), so you'll have to upgrade before then or be cut ...

You should be fine with UEFI. Instead of worrying about whether or not to install 14.04, you could just install the final beta version found here: http://mirror.cse.ucdavis.edu/releases.ubuntu.com//trusty/ Then just update as updates become available. Usually the final beta version is pretty stable. Or you could just install 13.10 and update when 14.04 ...

The Windows RE cannot be loaded directly from GRUB, as it requires bootmgfw.efi to call it. The only way to get to it is through Windows 8 because it relies on the underlying framework of Windows to be loaded. As long as you did not move the original partitions (Windows RE and Windows 8) around, you should be able to get into through Windows. Otherwise, ...

I had almost the same problem (see here) (same machine!), adding/changing the normal start entry (Windows 8 (loader) (on /dev/sda4)) to setparams 'Win8' set root='(hd0,gpt1)' chainloader /EFI/microsoft/BOOT/bootmgfw.efi fixed that one. Still, I could not get the recovery-one to work. I really do need that one. Did anyone find any solution to that yet? ...

Three options occur to me: Use the Linux port of the bless utility. This is now available in the Ubuntu archives (at least for 14.04), but I'm not sure when it was added. I have yet to properly document this in the rEFInd documentation, but it's on my list of things to do. Install rEFInd on the ESP using the fallback filename of EFI/BOOT/bootx64.efi (or ...

First, if you really meant Ubuntu 12.10, that version reaches end-of-life (EOL) status next month, according to this site. I therefore recommend updating to 13.10, or perhaps even 14.04 LTS (which is in beta-2 now, and will reach final release status next month). The current issues I am experiencing are: 1) rEFIt shows a confusing population of ...

As per you screen shot, your drive is set as dynamic (see below disk0 in image). Unfortunately this dynamic disk and partition are only recognizable in windows OS. Not only ubuntu, no other OS will recognize the partition. Linux boot loaders can not be installed in dynamic disks. The only way is to convert it basic driver. But for that you need to delete ...

I can only speculate, but my 2 initial thoughts would be: You might have an unsupported storage controller. Try connecting a usb stick and see if it's partition table / filesystem is readable. Since the usb stick will be using the usb controller not the sata/ide/etc controller it might show up properly. It would be helpful to note if you are using any kind ...

This is clearly a firmware (what manufacturers and most people call a "BIOS," although it's not) bug. I recommend you go to your manufacturer's site and look for an update. If that fails, my only suggestion is to use a third-party boot manager that will provide its own way to boot an external medium. My own rEFInd should do this, although in some cases ...

Jake, I had same error when I was trying to install EFI ubuntu 12.04. I had created an 300Mb EFI partition with gdisk (code ef00) on /dev/sda1/ using LiveCD, but I forgot to format the partition with mkfs mkfs -t vfat /dev/<efi partition> which solved the issue for me.

I have three suggestions: Abandon GRUB 2 -- Several other EFI boot loaders for Linux are available, and when you start running into GRUB 2 problems, these alternatives are likely to be easier to configure than GRUB 2, which is complex and finicky. Chances are either rEFInd or Fedora's patched GRUB Legacy will work best, although with some adjustments to ...

If you have preinstalled Windows 8, your probably have a UEFI Bios system, in which case the safest way to install ubuntu in my opinion is to switch the UEFI to Legacy.

First, verify that Windows is booting in BIOS/CSM/legacy mode. Windows 8.1 booting in that mode is certainly plausible on a self-built computer, but you should be 100% certain of what you're dealing with. Second, the simplest way to get Ubuntu to boot in BIOS/CSM/legacy mode is to remove the EFI boot loaders from the Ubuntu boot medium. If you're booting ...

There are two types of "fast boot" options: In Windows -- This option, generally called Fast Startup, Hybrid Boot, or Hybrid Shutdown, turns a shutdown operation into a suspend-to-disk operation. As such, it leaves filesystems in an inconsistent state, which means that they will be, at best, ignored by Linux or other OSes. At worst, they'll be mounted and ...
