    [SOLVED] Will the new Windows 8 PCs work with only Ubuntu installed?

    ...
    RE: New laptop with Windows 8 installed.

    Will these new Windows 8 PCs, laptops in particular --- work with only Ubuntu installed?
    With no Windows installed, only Ubuntu.

    If not, why?

    Have you seen it done successfully (or unsuccessfully)?

    Or is dual-boot the only way to get Ubuntu onto a 2013 laptop?

    I don't want Windoz on my new (under $400usd) laptop if I can help it.

    What brand? Some seem more forgiving than others. Some have modified UEFI code that with secure boot on they will only boot the Windows efi file. That is not per the UEFI standard.

    Only a couple of posts have been total erasing Windows drive. One or two used UEFI, not sure if secure boot worked or not. Others revert to CSM/BIOS/Legacy mode, but that will not boot Windows as it is a UEFI with gpt partitioning only. And CSM does not have secure boot. But then we never had secure boot on any system until Windows required it with Windows 8 on new computers.

    the whole UEFI thing is more about control than security

    One user posted he always buys a better system, but with only a hard drive. Then he total removes hard drive and puts it on shelf in case he ever wants to sell system and installs a new SSD and installs Ubuntu.

    Ubuntu will install in either UEFI mode or BIOS mode to gpt partitioned drives. But it depends on how you boot install media. If you boot in UEFI mode it installs in UEFI mode.

    I have ubuntu unstalled on my new lenovo, it originally came with 8 preinstalled. The only bummer is that you can't take what was installed and put it on VB

    Oldfred, thanks for your reply.
    I took back the ASUS x501a laptop because it had no optical drive
    and I think in the future I may want one. I do have a new portable usb
    optical drive, but with UEFI win8, I wasn't able to boot from it. I did
    get the ASUS to boot from usb-stick. But I didn't install Ubuntu, just
    tested the live session.

    Now I have a HP2000. I've successfully booted my Ubuntu-secure-remix
    (Ubuntu 12.10) usb-stick and tested the live session. I suppose soon
    I'll have to get up the courage to install it. But I couldn't get the optical
    disk version of Ubuntu-secure-remix to boot from the optical drive.
    Also having a problem getting directly to the bios so I can change
    boot order. Work-in-progress!!

    Thanks also for the urls. I read both plus a couple others of similar
    topic. So it seems for the commoner, like myself, we are going to have
    to wait until May/June. And I'm still not sure if I will be able to run
    Linux only on my laptop. I still don't understand the hardware and
    firmware involvement. So it is still not clear to me if it is possible
    to run Linux on a 2013 win8 laptop with win8 removed just as we
    could do with Vista and XP laptops. But it seems we can't as yet.

    I'm very busy now with preparing to move to California USA. Since
    I'm 74 years old, it is a tiring experience and I don't get much time
    to concentrate on this issue. So I'll probably just be satisfied with
    dual boot win8 and Ubuntu-secure-remix for now.

    Thanks again.

    Some users with HP, hopefully they use similar UEFI implementations.

    Oldfred, thanks again for your reply.
    I had heard of a HP p6 YouTube video,
    where they wanted to alter the Win8 partitioning
    because of too many primary partitions,
    but I couldn't find it.

    I installed Ubuntu secure remix, but forgot to do
    the last part, running the boot repair tool.
    As a result grub doesn't work as yet. But I'm
    confident that tomorrow I'll get it working,
    time premitting.

    see this series:
    Practical UEFI Secure Boot, a 3-part series by channelintel.
    http://www.youtube.com/watch?v=eAnlhkbMang
    Part 1. Installing uefi, was over my head in places.
    Part 2, installing Windoz 8, was not so difficult.
    Part 3, installing Ubuntu, was great IMHO.
    But this series didn't tell me if Ubuntu can be the sole OS.
    I think it can be done, but not with newer Intel CPUs.
    My new HP laptop has an AMD E-300 processor.

    If you are builting a PC, it might be a good idea
    to check what processors are UEFI.

    Good night

    Re: Will the new Windows 8 PCs work with only Ubuntu installed?

    With UEFI you have gpt partitioning and there is 128 partitions essentially all primary. So partitioning is not an issue, but UEFI with secure boot is. And it really is the secure boot. Some work, Some only boot Windows with secure boot, some only boot both with secure boot off. It seems every user has to experiment.

    But all UEFI have CSM or BIOS mode, so you can revert to BIOS. But if Windows was pre-installed it will only work with UEFI. If you have to have BIOS, then you have to also buy a full new install of Windows.

    Of course with BIOS you are back to the 4 primary partition limit. Windows has to boot from primary partition, but Linux works just fine from logical partitions.

    Re: Will the new Windows 8 PCs work with only Ubuntu installed?

    May I ask a question? Speaking without practical experience of any of these issues, I wonder which holds most risk from installing Ubuntu on these machines?

    1) Using the Install alongside option?

    2) Use the Entire Disk (Erase Contents) option?

    3) Do Something Else option?

    Surely the Use the Entire Disk option must be the least risky of the three options. Especially, if we do not want to keep Windows. But as with many things Linux related someone has to be the first to experiment. I have heard of a serious problem with a certain Samsung product that would make the machine unusable due to improper implementation of the specification.

    Is it possible to buy any machine meeting the Microsoft Windows 8 specification without Windows 8 pre-installed?

    Regards.

    It is a machine. It is more stupid than we are. It will not stop us from doing stupid things.

    Re: Will the new Windows 8 PCs work with only Ubuntu installed?

    Several users have posted they totally erased Windows and system worked. Not sure if they converted to CSM/BIOS or not in all cases. A couple did convert to BIOS boot and with secure boot off and sytem set to use CSM or BIOS it worked like an old system. But they may vary by vendor.

    Ubuntu will boot in BIOS mode from gpt partitioned drives. I gpt partitioning on my BIOS based systems as I have gpt on my SSD and even a flash drive. So either MBR(msdos) or gpt(GUID) will work with Ubuntu in either UEFI or BIOS mode booting. Ubuntu may work with secure boot without Windows on some systems, but some seem to have modified UEFI to only boot the Windows efi file. (Not per UEFI standard).

    Just thought I'd check in for a moment.
    Then it is back to fixing/painting our home.

    I know about the 128 primary partitions w/ UEFI.
    But at the time I was searching for the HP-P6 YouTube video, I didn't.

    I've been told installing Ubuntu as the sole OS
    depends on your processor/motherboard.
    So Using the Whole Disk may be dangerous
    on some of the new stuff,
    Intel processors especially.
    I won't try it on my new HP2000 laptop.
    I've been working side by side w/ windoz for years, so I can continue.

    This evening I hope to get time to fix my grub.
    Then I'll be back.

    Thanks for the replys.
