Public bug reported: I am currently trying to install Ubuntu 14.04 on a Sony Vaio that came pre-installed with Windows 8 in UEFI mode. And I am experiencing the dual-boot hell. I already tried most of the suggestions in the exhaustive "Installing Ubuntu on a Pre-Installed Windows 8 (64-bit) System (UEFI Supported)" ( http://askubuntu.com/questions/221835 /installing-ubuntu-on-a-pre-installed-windows-8-64-bit-system-uefi- supported ) guide as well as "Ubuntu installations when using UEFI" ( https://help.ubuntu.com/community/UEFI ), but I still experience issues.
These are the steps that I already did: 1. Use a 64-bit 14.04 2. In the BIOS I could NOT find nor disable QuickBoot/FastBoot and Intel Smart Response Technology (SRT). But I did disable FastStartup in Windows 8. 3. In BIOS I disabled SecureBoot. 4. I installed 14.04 in UEFI mode (the /etc/fstab contains the UEFI partition) by using manual partitioning on the GPT hard-drive. I reduced the size of the Windows 8 partition from within Windows 8, as recommended. 5. After the installation I noticed dual-booting issues, so attempted to use boot-repair (following this guide). But it only ended in an error and didn't fix much. Issue: Windows 8 always boots fine. When somehow I manage to get to the grub screen then choosing Ubuntu or Windows 8 will result in either OS booting just fine. So dual-booting sort of works. However, most of the times the Vaio will simply boot to Windows 8 after a shutdown or restart. To get to the grub screen reliably, I am currently using the following ugly workaround: 1. While holding the SHIFT key, I click on Restart within Windows-8 2. When the menu below appears, I select 'Use a device' 3. Then I select Ubuntu 4. Afterwards the GRUB menu appears and I can boot Ubuntu. For this to work I had to enable External Device Boot in BIOS and set in the Boot priority that the External Device (1) should be before the Internal HDD (2). I was instructed to report this issue as a bug against `shim`, and to mention in the report specifically that I: + installed Ubuntu in UEFI mode + left Secureboot enabled initially, but then disabled it when I couldn't boot Win8 from within GRUB + already ran Repair Boot with no luck + already left an empty unallocated space for Ubuntu (to install alongside Windows ) See discussion on this issue at AskUbuntu: http://askubuntu.com/questions/458413/how-to-fix-dual-booting-windows-8-and-ubuntu-14-04-on-a-sony-vaio Random thoughts: It seems to me that at some point there is a firmware issue at play here with the Sony Vaio laptops: their `Assist` button feels very awkward. On the Vaio you need to shut down the laptop, then hit Assist to enter into "Maintenance" mode, and only then you can access the BIOS. Please let me know if any other details are needed by the developers.
