    Anything I should know about Ubuntu and this set up?

    Hey guys,

    Not new to Ubuntu but have built a new computer, or will tomorrow, anything I should know about amd64 Ubuntu and this set up:

    Phenom II x6 3.3ghz 1100T Black Edition Thuban
    16 gb (4x4gb) G.Skill Ripjaw series 1333 mhz ram
    ASRock 880G Pro3 MOBO AM3+ Socket support
    Asus EAH6850 GPU
    Crucial 64 gb 2.5" SSD (intend to give Ubuntu half or less for is root and put /home on HD listed below, the rest will go for Windows 7 Ultimate 64-bit)
    2TB Seagate Barracuda 7200 RPM SATA III HD


    Just to let you know the rest:
    Case:
    AZZA Solano 1000 Full ATX Case
    Koutec IO-RCM621 All-in-one USB 2.0 3.5" card reader
    Sony DVD/CD +/- ROM


    I might buy another 2 TB HD sometime soon so I have 2TB storage in NTFS for Windows and 2 TB storage for Ubuntu. Then again, I have never had a problem with Ubuntu messing up NTFS, how common do you guys think it is? I would put the /home partition of Ubuntu in ext4 though, or just buy a smaller SATA III drive for the /home itself.


    Thoughts guys? Words of wisdom/warning?

    Thanks,

    AlphaA

    Nothing out of the ordinary from me. Install 64 bit, put windows on first.

    It looks like your motherboard is UEFI. That works in win7 64 bit. Grub2 is just starting to work with Natty.

    Win7 64 bit only works with gpt if UEFI booting.

    Re: Anything I should know about Ubuntu and this set up?

    Oldfred has provided you with a lot of useful links. It's worth reading them; but to give you an overview: Because you've got a UEFI board, your system will necessarily boot in an entirely different way than would a BIOS-based system, and Windows must use GPT partitions on a UEFI system, so you must use GPT (at least on the Windows boot drive) rather than MBR. These aren't disadvantages, really, over BIOS, but they are different, and the differences can bite you if you go at it in the usual way you'd install on a BIOS-based system. Some specific points:


    • Use Ubuntu 11.04, even if you have to install the beta; AFAIK, earlier versions lack the ability to boot the installer on UEFI.
    • Install the 64-bit version, not the 32-bit version; the 32-bit version's installer might not boot, and even if it does, there are said to be limitations when running a 32-bit kernel on a 64-bit UEFI. (I'm a bit foggy about how important these are, though, so I can't elaborate on this point.) You'll also need to install the 64-bit version of Windows, BTW.
    • Partition using GParted or gdisk in the Ubuntu installer disc: Create a 100-200 MiB (note MiB, not GiB) EFI System Partition, a 128 MiB Microsoft Reserved partition, and whatever partitions you want for Windows and Linux, as per the Microsoft document that oldfred referenced.
    • Install Linux first (not Windows, as is advisable on BIOS-based systems). Install Windows last. The reason for this order is that the Ubuntu installer, at least according to reports from one beta user, wipes the EFI System Partition clean, and with it wipes out the Windows boot loader, when it installs. This renders Windows unable to install. Installing in the other order should work better, but few enough people have done this that I can't be positive of that.
    • Read over the GRUB Testing on UEFI page (the name's changed from what oldfred provided). It talks about building GRUB for EFI from scratch, so much of that procedure might not be applicable; but there was a thread here recently started by somebody who installed to a UEFI system, and as I recall, he ended up having to build GRUB from scratch to get things working correctly. (I might be disremembering, though. I think it was this thread, but I'm not positive. It's a monster 10-page thread and the fact that the system used UEFI didn't emerge until at least halfway through it, so there's a lot of bad BIOS-based advice before [and even after] then.)



    The special issues you'll encounter are all related to booting and installation, AFAIK; once the system is up and running, you'll have no special problems. I do recommend, though, backing up the contents of the EFI System Partition (mounted at /boot/efi by default) and of the entire /boot directory. That way, if a system update tries to upgrade a modified GRUB configuration and gets it wrong, you'll have something you can restore that should work.

    Incidentally, in case you're thinking this UEFI thing isn't worth the bother, know this: Windows requires an MBR disk to boot from in BIOS mode, and MBR is limited to 2 TiB. Thus, you can't boot Windows from a larger disk if you use BIOS. (There are some workarounds, but they've got their own problems and limitations.) In other words, UEFI "future-proofs" the Windows side of your installation, in terms of hard disk size. At this point, I wouldn't recommend buying a BIOS-based computer if it's to run Windows for this reason.

    You also asked about NTFS. Ubuntu's NTFS support seems anecdotally to be pretty good; however, it's slower than Linux-native filesystems, and it's even slower than FAT. I also find it hard to believe that it's as reliable as Microsoft's NTFS support. Thus, I strongly recommend against using Ubuntu's NTFS support to read, or especially to write, your Windows C: partition. Use a separate data-exchange partition. If you expect to need to access most of your files from both OSes, then this might be the bulk of your storage space. If not, though, using a Linux-native filesystem (probably ext4fs) for storing your Linux-only files makes sense. If you don't need to store files larger than 4 GiB, using FAT rather than NTFS makes sense; FAT is faster under Linux and Linux provides decent FAT filesystem maintenance tools, unlike for NTFS. That 4 GiB limit of FAT can be a real pain if you plan to store big audio-visual or backup files, though.
    If I've suggested a solution to a problem and you're not the original poster, do not try my solution! Problems can seem similar but be different, and a good solution to one problem can make another worse. Post a new thread with your problem details.

    Re: Anything I should know about Ubuntu and this set up?

    Thanks for all the great replies guys. I don't know if I am ready to mess around with beta versions. Maybe I'll just wait until it comes out in a few days. Though I hate the new Unity look, I'm sure there will be a gnome version though by some one. Also, what about using lilo? I see Archlinux says that GRUB2 officially supports booting from UEFI boards.

    Unfortunately, when I bought this MOBO it didn't say anything about UEFI so I thought it was BIOS. I should have done more research, but it seemed like a good deal. I think I'll look around to find a very clear walkthrough for the install.

    Thanks guys,

    Re: Anything I should know about Ubuntu and this set up?

    I tried Unity for a bit, and may eventually use it on my laptop as it is wide screen. But my desktop has a 4:3 monitor and having the bar on the left makes no sense, top & bottom are where I have extra room.

    With Natty, I changed to gnome, on selection at login screen & it has booted to gnome ever since.

    Re: Anything I should know about Ubuntu and this set up?

    I should have thought of this earlier but I can do a seamless upgrade from 11.04 beta to 11.04 without having to reinstall can't I? Is this recommended? I kind of regret my UEFI purchase now, but I am going to make it work one way or another.

    Re: Anything I should know about Ubuntu and this set up?

    You should be able to continue to upgrade. I usually do a clean install, just to make sure I have housecleaned out all old stuff, but updating works. With larger drives I create several / (root) partitions of 25GB and test installs and keep older versions, so I know I can boot something.

    I wanted to purchase a EFI system when I build this one several years ago. But then they only had server boards for several thousands $. I was a lot ahead of the curve. You are just on the brink of all new systems using UEFI and might regret having BIOS a year or two from now.

    Mac users have been dealing with this for a bit. It sounds more complex than it is in reality (I am multi-booting my macbook pro). The movement away from mbr is a blessing.

    I agree. Given Windows' inability to boot on >2TiB drives on BIOS-based systems, and given that Microsoft, by all accounts, seems uninterested in fixing this flaw, I expect there'll be a lot of frustration in a year or two among Windows users with BIOS-based systems. Of course, if you regularly replace your computer every two years or so, this might not matter; but as I wrote above, UEFI at this point is a future-proofing technology. OTOH, you can't boot Windows XP or earlier on these boards, but you can certainly run such OSes in a virtual machine -- they have their own "firmware" that can be of a different type than that on the real computer.
