    Re: UEFI boot Issue with Alienware X51

    You can easily post screen shots or camera photo (reduced in size) by using the paperclip icon in the edit panel of your message. Also you can use gdisk to list partitions. I suggest adding gdisk as it is a tool to see & edit gpt partitions.

    Not sure if it is true with gpt drives, but with MBR we always suggest to use the Windows tools to shrink the Windows NTFS partition, then reboot several times, so it can run chkdsk and recognize its new size. Also backups of the Entire Windows & a Windows repairCD should be made just in case. Also backup efi partition, there was a bug in earlier versions of the installer/grub that overwrote the efi. It is fixed in current version, but if you happen to try an older install it still will have that bug.

    Ubuntu will run in as little as 5GB, but that requires significant effort to regularly houseclean. It depends a lot on what you plan to do and if not sure the default install of just / (root) and swap in the 50GB unallocated is fine. Alternates are two added partitions, a separate partition for /home and separate NTFS partition for shared data.

    I usually suggest separating systems (both Windows & Linux) from data. Since /home is mostly data many of us suggest separate /home partition.

    And Windows does not like a lot of writes into its system partition. LInux' NTFS driver exposes all the normally hidden files & folders so it is easier to accidentally move or delete something. I used to unhide everything in Windows and regularly did something that required major repairs. So I might make the Windows system partition smaller and create a shared NTFS data partition. That was the first thing I did with my system and it allowed me to move the Firefox & Thunderbird profiles to my shared. Then I did not have to reboot to see email or have all my bookmarks from Windows.

    You can use gparted to create the Linux partitions as it works with gpt partitioning, if you want to create partitions in advance. One advantage of gpt is all partitions are primary. I do not notice any difference in using gparted with gpt drives or MBR other than there is no logical drives.

    My standard suggestion, others may have different opinions and many of us use system differently so needs vary. I find my own optimal partitioning is not so good a couple of years later, but then buy a new drive anyway.

    For the Total space you want for Ubuntu, You already have the efi partition, an do not need the bios_grub if only booting UEFI:
    Ubuntu's standard install is just / (root) & swap, but it is better to add another partition for /home:
    If gpt(not MBR) partitioning include these two first - all partitions with gpt are primary
    250 MB efi FAT32
    1 MB bios_grub no format
    Ubuntu partitions - smaller root only where hard drive space is limited
    1. 10-25 GB Mountpoint / primary or logical beginning ext4(or ext3)
    2. all but 2 GB Mountpoint /home logical beginning ext4(or ext3)
    3. 2 GB Mountpoint swap logical

    Depending on how much memory you have you may not absolutely need swap but having some is still recommended. I do not hibernate (boots fast enough for me) but if hibernating then you need swap equal to RAM in GiB not GB. And if dual booting with windows a shared NTFS partition is also recommended. But you usually cannot create that as part of the install, just leave some space. Or partition in advance (recommended).
    One advantage of partitioning in advance is that the installer will use the swap space to speed up the install. Thanks Herman for the tip.

    Re: UEFI boot Issue with Alienware X51

    You certainly provided a lot of information! However, I not exactly partition-savvy when it comes to this.

    The Ubuntu installer told me, "No operating systems detected." I hope that is okay!

    I started out by making a 100 GB unallocated partition in Windows Disk Management.

    So should I create a 50GB NTFS partition to use as data across Win7 and Ubuntu?

    And near the end of your post you said that I should make another 250MB efi partition, dont I have one already? Im just confused about the end of your post.

    I know respected forum members are hesitant to give step by step instructions for newbs like me, but to be honest, it seems like that is exactly what I need right now. Is it possible that I can just use the partition manager in the Ubuntu installation instead of using gparted?

    If it makes it easier, I dont need to use hibernation on my pc.

    I dont know anything about this, heck I didn't even know what a MiB was until today!

    The installer should see your Windows. Not sure if with UEFI it it somehow different or not.

    My standard instructions assume a blank drive, so you already have the efi partition and that is fine.

    I find it best to use manual partitioning and then use manual install. I do not want auto install to go off and accidentally delete everything. And if it is not seeing your Windows it is a problem.

    If you go into manual install does it show the existing NTFS partition(s)? I have use the install to unallocated space but again with UEFI everyone before has posted it works best if partitions are created in advance with gparted. You can use gparted tutorial to understand it better.

    You need the /, /home & swap partitions and optionally the NTFS shared data partition, 50GB should be fine. It really depends on how much data you may want to share.

    Re: UEFI boot Issue with Alienware X51

    I can see all 3 of my NTFS partitions: Recovery, Win7 OS, and my new 50GB partition for file sharing.

    I have a warning symbol next to my /dev/sda3 partition, the one with the flag msftres. Maybe that is what is causing my operating system to be undetected? As of writing, in gparted running in Ubuntu Live USB, sda3 is the only partition with the warning icon next to it.

    When I am done making these partitions, when installing Ubuntu manually, what do I select for "Device for boot loader installation?"

    Re: UEFI boot Issue with Alienware X51

    With UEFI booting, Windows has a hidden unformated partition for some code. That is just the Microsoft reserved area & should be ok. Gparted cannot parse unformated partitions.

    With UEFI you choose the efi partition which should be sda1 as the location to install grub. You are installing grub-efi not the BIOS grub-pc version.

    Re: UEFI boot Issue with Alienware X51

    Okay, I got everything working thanks to both of your guys' help. I have my system set up to load windows by default and if I press f12 on startup I can select ubuntu.

    Ill make sure I mark this thread as solved once I get back from a walk.

    Again, I cannot stress how helpful you two were, truly exeptions to the usual comments I have gotten on other threads.

    Re: UEFI boot Issue with Alienware X51

    I know this has been solved but my issue is I have wiped windows off and made Ubuntu my sole OS on the X51. After I installed it and rebooted it comes up with the purple backround for the Ubuntu load screen but after it goes black then nothing loads. Is there anything I need to change towards BIOS. Here is my Partition:

    1gb to "EFI"
    1gb to "BootGRUB"
    3gb to "/boot"
    40gb to "/"
    3gb to "swap"
    and the rest went to /home.

    Re: UEFI boot Issue with Alienware X51

    If you are booting and get grub menu, or can get it with shift, then it is probably video issues. Do you also have the dual video which is another can of worms.

    I think in UEFI/BIOS you need to set to boot with one or the other video chip to get it working.

    Re: UEFI boot Issue with Alienware X51

    When I installed it from my live dvd I changed quiet splash to no quiet no splash nomodeset just to get it to load. I then went to trial it before install. There I went into the termenal to change the grub but it wouldn'tlet me update the changes. Do you think that might have something to do with it?

    Re: UEFI boot Issue with Alienware X51

    With my nVidia 9600GT on an older system, I have to remove quiet splash and use nomodeset on all liveUSB boots and first boot after install. Once nVidia driver is installed then I have no issues.

    If you only have Ubuntu you may not get grub menu. Holding down shift from BIOS should get grub menu. Not sure if that is now fixed if in UEFI mode, there used to be a bug.
