    Unhappy Dell Studio 15 Ubuntu not seeing Partitions

    Hello Linux Community. I have wanted to install Ubuntu on my Dell Studio 15 laptop for a month now and finally have the time to do it. My problem is when I try to install Ubuntu 10.04, the installer only shows my whole hard drive as "unallocated space." I do have Windows 7 on part of my hard drive that I wish to keep along side with Ubuntu. I tried partitioning the hard drive in Windows 7. It worked and says 80GB of unallocated space on my 320GB hard drive.

    What is wrong? Why will my whole hard drive show as unallocated space on Ubuntu Live CD, but on Windows it shows the correct only 80GB partition.

    My specs on a Windows 7 64-bit system:
    Dell Studio 1558
    320GB SATA Hard Drive
    4GB DDR3 Ram
    Intel i5 Processor M520 @ 2.40GHz
    ATI Mobility Radeon HD 4500 Series

    Run the live CD/USB until you get to the desktop, then double click the Install ubuntu icon. At the partitioning page choose manual partitioning, the third option, I think, and see what partition layout that shows. I should show your current Win7 OS plus any Restore partitions and Boot partition that Win7 seems to always have, as well as the unallocated space you have made.

    If any problems come back again with screenshots from the live CD, if possible; just hit Print Screen key to do that, and then copy the pic back here as an attachment.

    First of all thank you for helping me. Here is the picture. At the screen before it the screen said "there are no operating systems installed.
    What is the problem?

    Re: Dell Studio 15 Ubuntu not seeing Partitions

    Windows 7 is still working. I noticed that while I was in the Ubuntu 10.04 Live CD that under the "Places" tab, a "a 234GB Filesystem" and "System Reserved" were listed. I clicked on the 234GB Filesystem and sure enough it gave me access to my Windows 7 partition. The System Reserved was the boot loader.

    OK, so now from the live CD run
    Code:
    sudo fdisk -l
    (lower case L at end) and report back output. You could also while in live CD run System >Administration >Gparted and attach a screenshot back here.

    Here is the screen shot. I tried to show the "Places" tab, but wasn't able to.

    Re: Dell Studio 15 Ubuntu not seeing Partitions

    It looks like you have a GPT (GUID) partition table, but as that really means nothing to me other than it's not a standard msdos type, I will point you to http://www.uluga.ubuntuforums.org/sh....php?t=1619381 where there seems to be a lot of info.

    Instead of fdisk, as the error tells you, try
    Code:
    sudo parted -l
    which should at least show you the partitions, and if parted does, I think gparted also should.

    Re: Dell Studio 15 Ubuntu not seeing Partitions

    The problem is not that the disk is a GUID Partition Table (GPT) disk, but that it used to be a GPT disk and was incompletely converted back to Master Boot Record (MBR) form, leaving residual GPT data structures that are confusing libparted (upon which the Ubuntu installer's partitioner and several other tools are based).

    I recommend you boot your Ubuntu installer into the "try before installing" mode (or whatever it's called), download GPT fdisk (gdisk) from its Sourceforge download page (you'll need the .deb file for your architecture -- i386 or amd64), install that packabe by double-clicking or typing "sudo dpkg -i gdisk_*deb" in a shell prompt, and then read this page from the GPT fdisk documentation to learn how to wipe the old GPT data. Note: Do not use the version of gdisk in the Ubuntu repositories unless you're installing the 11.04 alpha; the version in the repositories for earlier versions of Ubuntu is hopelessly out of date. IIRC, it's got bugs that will make matters worse if you try to fix the problem with it.

    Thank you so much both of you. So with GPT fdisk, what will it do to my hard drive? Will it change it to a Master Boot Record so Ubuntu will funciton normally on my computer? Will I still be able to use the Grub 2 bootloader with Windows 7 and Ubuntu 10.10 when I upgrade?

    The whole GUID makes sense now. About a month ago I tried to do a hackintosh and couldn't get it. I decided to just reinstall Windows, so did I forget to format my hard drive back to an MBR?

    Also, I noticed that I wasn't able to access my Windows 7 files. When Ubuntu installs, will I be able to?

    Finally, if I get Ubuntu installed, will I ever have any more problems with the GUID partition table or installing any other files?
