[Bug 711159] Re: Ubuntu 10.10 installer crashed

[Brian Murray]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. While we appreciate the difficulties you are facing, it
would appear that the CD image (ISO file) you downloaded could be
corrupt. There is an easy way to verify the integrity of the Ubuntu ISO
files you download. Could you please visit
https://help.ubuntu.com/community/HowToMD5SUM follow the instructions
and report back as to whether or not the MD5SUM verified? Thanks in
advance.

Title:
  Ubuntu 10.10 installer crashed

Status in “ubiquity” package in Ubuntu:
  Invalid

Bug description:
  Binary package hint: ubiquity

  I have a 250GB disk that I split into 3 partitions using the Windows 7
  setup DVD. Windows 7 created its own 100MB partition at the beginning
  of the disk, totalling 4 partitions. So, partition 1 (100MB) is used
  by Windows (System Reserved). Partition 2 (50GB) contains the Windows
  7 installation. I reserved partition 3 (50GB) for Ubuntu 10.10, and
  Partition 4 (132GB) is reserved for Data, which I want to be
  accessible to both Windows and Ubuntu.

  I followed all the steps in your Ubuntu website to create a bootable
  USB stick (2GB), and I downloaded the latest Ubuntu ISO image (10.10
  x86) to complete the USB loader process. It booted just fine, and
  started the GUI wizard from the USB stick, offering the option to Try
  or Install Ubuntu. I selected Install, and manual partition. I then
  deleted partition 3 using the Ubuntu setup GUI, and recreated it as
  Ext4 file system, with format enabled and "/" as the device. It
  continued without problems to connect to my ADSL internet connection,
  prompted for the time zone and started installing. After a few seconds
  it crashed stating that there's a problem with my CD/DVD drive. This
  is strange, because it is a fairly new laptop computer, and Windows
  didn't complain about the drive at all. (I installed Windows 7 from a
  DVD.) Also, there was nothing in the DVD drive when Ubuntu setup
  complained.

  I rebooted into Windows and ran a defrag and scandisk to check for HDD
  errors, but no errors were reported. I even tried to clean the DVD
  drive with a commercial DVD cleaner, and tried to install from a re-
  dowloaded Ubuntu 10.10 ISO DVD. That produced the same error. So I
  burned the ISO to a CD instead, but it produced the same results.

  Apart from manually selecting partition 3 I accepted all the defaults
  offered by the Ubuntu GUI. I don't think the partitioning is the
  cause, because I performed exactly the same configuration on another
  laptop computer, using Ubuntu 10.04, without any hiccups.

  How do I proceed from here? Is there a way to tell whether the ISO
  image is corrupt? I have now downloaded 3 copies in total, all exactly
  the same size in bytes. All produce the same errors.
