My journey into hell began about two months ago when I purchased a new HP laptop computer with Windows 8 preinstalled. The machine was fast, worked great and was cheap. It has a quad core CPU, 8 gigabytes of Ram with AMD Radeon 7640G graphics that can use up to 4 gigabytes for video processing. (512 MB dedicated called discrete graphics). It played everything I threw at it on high settings with great frame rate such as the new Skyrim, Black Ops 2 and Far Cry 3. All for only 400 US dollars. I could not be happier with my purchase... Then I tried to dual boot Linux and the world came crashing down around me.
I knew nothing of UEFI then or Microsoft's requirement of OEM's to use UEFI's Secure Boot feature with Windows 8. Now, I wish I had. Unified Extensible Firmware Interface - Wikipedia, the free encyclopedia
UEFI, or EFI is slated to be the replacement for Bios and it's been around for about 20 years. Trouble is, it's buggy and no one wanted to use it. There is good reason why OEM's have dragged their feet for years with this technology. It's still getting the kinks worked out. See here for more: EFI and Linux: the future is here, and it's awful - Matthew Garrett - YouTube
So, I started studying this technology. I found out that what most new consumers have that come shipped with Windows 8 is a bios based system with a UEFI layer implemented, but not always. Some systems have a full UEFI with no Bios and some are UEFI based with a compatibility layer of Bios. Most of the time you wont know which type of system you are buying until it's too late as the OEM's who are Microsoft partners don't advertise this information. One things for certain, if you buy a PC with Windows 8 preinstalled you will have some type of UEFI and you will have Secure Boot enabled.
Secure Boot acts as a protection feature that is supposed to ensure your system doesn't have any malware at the time of shipping. It works by checking keys in the operating system against hard coded keys in the UEFI. As these keys are signed by Microsoft, the system will not allow any other operating system to boot assuring you have a clean copy of Windows 8.
For Non ARM based PC's Microsoft requires the user have the ability to disable Secure Boot. Once this is done, Windows 8 will boot normally although still using UEFI for it's IO to the hardware. On many machines you also have the ability to turn off UEFI and boot Windows from Legacy Bios mode.
The problem with dual booting Linux either with UEFI off or Secure Boot disabled is it's not a proven technology that works well even if you do have a distro like Fedora or Ubuntu which supports UEFI and Secure Boot. I spent weeks fighting with getting Linux Mint to work properly in UEFI with Secure Boot disabled getting advise from top professionals - people who know UEFI well enough to write software for it. If the system was installed under UEFI in the first place, you can count on having your share of trouble.
I contacted HP's tech support and went round and round trying to explain the issues to people reading scripts off a card and checking with their supervisor with every sentence because they simply lacked the ability to understand the issues. In the end, I was told HP doesn't give support for UEFI, and I should please contact Microsoft.
Which is silly because Microsoft has nothing to do with the bios/UEFI in the machine, they only require it's use. In fact, you will not find one mention about UEFI in any HP documentation - at all. Not on the website, not in the advertising, not in the user Maintenance and Service Guide.
I wanted answers. I went over the tech supports heads and spoke to someone (I wont mention her name) who is a: Case Manager for "HP AMS TCO Escalations Team" I'm not exactly sure what that team does but they are supposed to have better answers than tech support. She didn't but told me some interesting things.
One reason all PC's that come preinstalled with a Microsoft operating system is cheaper than regular laptop is that Microsoft subsidizes the cost of the hardware. This amounts to being paid off in my book. It's a legal bribe.
The case manager claims this is common knowledge and all OEM's have this same agreement with Microsoft. I asked if she could provide me a reference to this online and she said it's not anywhere online that she knows of. I'm not too surprised at this.
If you read through the Windows 8 Hardware Certification Requirements for Client and Server Systems, found here: Windows Hardware Certification Requirements for Client and Server Systems , you will read about functionality you are supposed to have, that OEM's agree to - that you may not find in your system. The case manager avows all is good because after all, Microsoft signed off on the certification for these systems HP sells - Wonder how they can do this and still have the product pass Microsoft hardware certification? They are scratching each others backs there is no other way to put it. The case manager made a point to tell me several times that because Microsoft subsidizes these systems they do not have to allow support for dual booting with a Non Microsoft system or give UEFI support or even provide any documentation on UEFI.
What's worse in my opinion is she made a point to state proudly they are very interested in Linux. They have several machines certified to work with Linux and they are even Platinum members of The Linux Foundation. It's not about the freedom to use your system as you want, it's about Money. Many people fear Microsoft doing these things knowingly to keep people from dual booting with Windows 8. I even recently defended Microsoft's rights here because I thought the author went overboard: My problem with the Free Software Foundation
After talking to this case manager, I'm not so sure I had all the facts. It certainly does look like there is something rotten in town and it's not looking good for dual boot users.
The best solution to all of this is if you have such a machine make backup copies of your Recovery Disks, uninstall the system completely, and reinstall in Legacy Bios mode. You don't really need UEFI at this stage unless you have a hard drive larger than 2.2 TB's. If you want to do a clean non OEM bundled install you may be able to obtain a Windows 8 ISO from torrent of the disks here: MSDN Subscriber Downloads ( You will still have to re-install all your drivers manually) You cannot download from this site directly if you are not a MSDN partner but if you obtain such a disk you can legally use it because the product keys and CD keys are embedded in the systems bios. This will be true for all OEM machines that come preshipped with Windows 8. The installation disk will check your keys and activate your Windows as legal on first boot. In HP's case, this also will not void the warranty, your OEM may be different.
Bottom line, if you plan to dual boot with Linux, don't buy a Windows 8 preinstalled machine or be prepared for headaches. Better yet, don't support these companies at all who have these shady business practices. Buy from a company who doesn't partner with Microsoft or build your own machine. I know for me, this HP will be the last I ever buy.
