    "This computer currently has no detected operating systems"

    I'm trying to install Ubuntu 11.10 on a dual boot system that currently contains an installation of Windows XP and another of Ubuntu 12.04 - I want to replace this with 11.10. while retaining the install of Windows XP. However, the 11.10 LiveCD installer says that "This computer currently has no detected operating systems", and gives me only 2 options:

    1) Erase disk and install Ubuntu
    2) Something else (manual partitioning)

    The output of fdisk -l is:

    Disk /dev/sda: 160.0 GB, 160041885696 bytes
    255 heads, 63 sectors/track, 19457 cylinders, total 312581808 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00073acd

    Device Boot Start End Blocks Id System
    /dev/sdb1 * 80 15663103 7831512 c W95 FAT32 (LBA)


    I'm wondering why the Ubuntu LiveCD installer apparently doesn't see the Win XP partition on sda1?

    Hi, I've noticed that you have a device mounted at /dev/sdb.

    Providing you are installing from CD, could you attempt to unplug the device and try again?

    Thanks,

    With the device unplugged (it's an 8Gb USB Lexar flash drive), the result is the same: I get the same two options, and the message that "this computer currently has no detected operating systems".

    In the manual partitioning screen there's an entry for /dev/sda - i.e. the 160Gb disk. It's the only entry there.

    There are one or two other threads about this topic, but they date from several years ago. e.g.

    and don't seem very conclusive, as far as I can see,

    Re: "This computer currently has no detected operating systems"

    Is is at all possible for you to take a screenshot of the partitions on the installer for me and attach it to your post?

    I wouldn't normally ask, but it would help to have a visual view of what's going wrong on your installer.

    Cheers,

    I have had gparted not even show my sda drive which then only had XP. Even though XP would boot. But then I ran chkdsk, XP booted a bit faster and gparted would show sda drive.

    You might try running chkdsk on the NTFS partition from your XP install disk.

    It's not really a screenshot, more like a snapshot - but here it is, anyway.

    Yes, that is a bit odd.

    I would suggest what oldfred suggested and run chkdsk on your WinXP system. It might be worth a try. When booted into WinXP as the admin user, go to the command prompt and type
    Code:
     chkdsk c: /r
    type Y in response the question about the volume being in use, hit enter and restart. If you could then attempt to run the Ubuntu installation again and report back.

    Cheers,
