I have a new lenovo laptop I am trying to install ubuntu 12.04.4 LTS on. I downloaded the ISO and burned a DVD from it. If I boot the laptop from the DVD, it seems to boot up fine. I get the desk top and the ethernet works (I am writing question from that desktop).

But when I click "Install Ubuntu 12.04.4 LTS" and click Continue from the Welcome screen and then click Continue from the "Preparing to Install Ubuntu" it hangs forever.

I had previously installed Suse linux on this laptop, but Suse didn't recognize the ethernet, so I decided to try ubuntu instead. Only reason I mention this is the laptop does not have windows on it now. I has ext4 partitions from the Suse install and I am fine with the ubuntu install rewriting the whole disk.

Other posters recommend reformatting the disk using the Disk Utility, but when I attempt to format the disk it fails with:

Error creating partition table: helper exited with exit code 1: In part_create_partition_table: device_file=/dev/sda, scheme=0 got it got disk committed to disk BLKRRPART ioctl failed for /dev/sda: Device or resource busy

So I figure I have to unmount something, maybe? Except nothing on this disk seems to be mounted:

ubuntu@ubuntu:~$ mount /cow on / type overlayfs (rw) proc on /proc type proc (rw,noexec,nosuid,nodev) sysfs on /sys type sysfs (rw,noexec,nosuid,nodev) udev on /dev type devtmpfs (rw,mode=0755) devpts on /dev/pts type devpts (rw,noexec,nosuid,gid=5,mode=0620) tmpfs on /run type tmpfs (rw,noexec,nosuid,size=10%,mode=0755) /dev/sr0 on /cdrom type iso9660 (ro,noatime) /dev/loop0 on /rofs type squashfs (ro,noatime) none on /sys/fs/fuse/connections type fusectl (rw) none on /sys/kernel/debug type debugfs (rw) none on /sys/kernel/security type securityfs (rw) tmpfs on /tmp type tmpfs (rw,nosuid,nodev) none on /run/lock type tmpfs (rw,noexec,nosuid,nodev,size=5242880) none on /run/shm type tmpfs (rw,nosuid,nodev) gvfs-fuse-daemon on /home/ubuntu/.gvfs type fuse.gvfs-fuse-daemon (rw,nosuid,nodev,user=ubuntu) ubuntu@ubuntu:~$

I'm stumped as to how to proceed.

Advice welcome,

Update on 3-10-2014, in response to question about type of system;

Its a Lenovo G500 15.6-Inch Laptop. The Amazon site I bought it from describes it like so:

Intel Core i5 3230M 2.6 GHz (3 MB Cache) 4 GB DDR3 500 GB 5400 rpm Hard Drive 15.6-Inch Screen, Intel HD 4000 Graphics

I don't think the problem is one of hardware compatibility. If I boot the system from from the DVD (as opposed to trying to install from the DVD), it seems to work fine (not sure about the wireless yet). It just seems that the install gets confused because it already has an ext4 file system from the Suse distro I installed on it previously. Other posters have referred to similar problems when installing this version of ubuntu on systems that didn't have windows on them and their fixes seemed to involve deleting partitions first or reformatting the disk drive.

But when I try to reformat the disk drive as suggested using the Disk Utility, I get the errors described above.

Try to install directly after boot, don't start Try Ubuntu before install before installation.

Thanks, but I tried that the first time. If I just select Install when the laptop first comes up from boot off the DVD, then it blocks forever in the "Preparing to Install Ubuntu" window. – user256552 Mar 10 '14 at 2:58
What is your laptop model/specs ? – Ahmadgeo Mar 10 '14 at 3:39

I have one of the many variants of the G500 and it runs 12.04LTS OK except the Atheros LAN is not recognised (but, strangely, the wireless is).

I suggest you run he Live DVD again and run Gparted (from the System menu) and delete all the partitions on the disk. Then try the install...
