Dual Boot With A Glitch In The Bios

Join Forum | Login | Today's Posts | Tutorials | Windows 10 Forum | Windows 8 Forum Welcome to Windows 7 Forums. Thanks @smileyyasha but this fix isn't relevant/applicable to EFI booting or dual boot. If you happen to install Ubuntu in Legacy Mode (No SecureBoot) you might have problems booting both, Windows and Ubuntu at the same time since they will both not appear on If the PC does not load Ubuntu (but instead loads Windows, for example, as in Bug #1050940), or if the Windows entry in the GRUB 2 menu does not boot Windows check over here

Known issues In one case, it is possible that dual boot could reveal a bug for existing driver of certain hardware, according to this Debian Wiki quoted below. Unfortunately, n practice, there are occasional BIOS/GPT quirks or even downright incompatibilities. I attempt install Ubuntu on the external hard disk and I can say quite success. Now before saving, some motherboards offer a Boot Mode option.

Arnav Bhattacharya. Secure Boot There is information on secure boot at rodsbooks, but for now I am going to leave it off. The bios was preset to AHCI mode.

There's no law that says that GPT can't be used with other computers, though. Thanks Nighthawk Been there, done that. share|improve this answer edited Jan 18 '16 at 23:28 community wiki 2 revs, 2 users 60%Shane Wiley 1 This does not provide an answer to the question. I was able return to Windows using Boot-Repair.

I'm very much looking forward to use the OS, but am unable to do so... Problem is described in this discussion. This is because the Intel drivers do not recognize the double LVDS link to the screen when no BIOS initializes it. http://askubuntu.com/questions/221835/installing-ubuntu-alongside-a-pre-installed-windows-with-uefi Hack the elections Is hiding my friendlist on Facebook a bad sign for the HR?

You are installing on an MS-DOS type disk scheme (You can only have 4 primary partitions as opposed to GPT Scheme) which has at least 1 Free Primary Partition. To properly make a bootable USB you need to download RUFUS. However Windows supports UEFI only with Vista for x86_64, SP1 and later (on UEFI 1.1), or Windows 7 (on UEFI 2.0), or Windows 8 (on UEFI 1.1), and only with GPT Obviously the option is self explanatory.

  1. In one case (a system with a dual-core AMD CPU and an AMI BIOS), booting was sluggish, but sped up when I made a random change to the GPT.
  2. But besides all that this could explain why the errors are being seen when everything seems normal.
  3. GPT was created as part of the EFI specification, so of course GPT works well with EFI-based computers.
  4. For those systems, you should use a Linux kernel compiled with the "Run EFI in physical mode" patch.

Just before wrapping up, though, my dual boot tests failed disastrously. directory Some of the notable UEFI firmwares are Phoenix SecureCore Tiano, AMI Aptio, and Insyde H2O.

Install a second disk that uses an MBR partition table, preferably with a partition marked as active/bootable. More tests Rod Smith advised me to do "mvrefind.sh /boot/efi/EFI/Microsoft/Boot /boot/efi/EFI/refind" to move refind to its normal location, in case it was later overwritten by Windows. How can K (kaon) and Σ (sigma particle) be created quickly via the strong interaction and decay slowly via the weak interaction? this content Reports of GPT/BIOS incompatibilities in such communities are rare, suggesting that even a 10% problem incidence is a gross overestimate.

Since usually there's only one Windows installed the menu selector of the Windows bootloader never appears giving the impression that the entry you added in the Linux bootloader actually loads Windows. You install one operating system and leave unallocated space on the disk, you then install the second operating system on that unallocated space, you then fix the boot strap ( GRUB/Windows efilinux Ubuntu 12.10 will use Intel's efilinux as UEFI bootloader in order to comply with Microsoft's UEFI Secure Boot.

That's not very satisfactory, though, because the system now always boots into Windows unless you hit F9 while booting.

I bought a new laptop back in April this year, after trying to check online for Linux certification to match what was in the local stores. cd /usr/src sudo patch -p0 -i v2-EFI-Run-EFI-in-physical-mode.patchthen recompile and install the kernel. In either case, a computer with a GPT disk may not boot or will boot very slowly because the BIOS power-on self-test (POST) takes an inordinately long time to finish. have a peek at these guys Determine your EFI SYSTEM PARTITION or create it (>=100 MiB FAT32 partition - GPT fdisk type code EF00 or GNU Parted 'boot' flag in GPT).

For those motherboards, download the x86_64 UEFI Shell and copy it to you EFI SYSTEM PARTITION as /shellx64.efi (mostly /boot/efi/shellx64.efi) . Note: After every suspend/resume, the discrete graphic card is powered up again, so you need to disable it through a command line program, which can be executed automatically on each resume The vast majority of computers sold with Windows 8 are also EFI-enabled, and in fact they ship configured to boot Windows in EFI mode.

With good unit tests, do I also need acceptance tests? I would in any case, send the bug report to the provided link above.

It is important to know whether Ubuntu's current kernel supports all of your hardware. I prefer to keep the working system. All of the full download (13Gb) had been done, verification over and after installing, the computer automatically restarted, but the option of Endless OS didn't come on the screen where I Apparently it will alter the ID of the Recovery partition.

Workaround exists for both cases above. Many things have been said in this answers and some of them are obsolete, as Hellreaver noticed. In there, create a 250 MB partition for EFI and the rest for GRUB and other stuff you are accustomed to. UEFI takes precedence.
