I have installed Ubuntu 12.04 on my preinstalled windows 7 Sony vaio s series laptop following instructions here: http://www.linuxbsdos.com/2012/05/17/how-to-dual-boot-ubuntu-12-04-and-windows-7/

Everything went well and I am able to boot in to windows after complete installation of Ubuntu. Now following instructions on web I tried to add Ubuntu to my BIOS using Easy BCD (but forget to add windows 7 entry). As a result, I loose windows 7 OS and can't boot in to either OS then I successfully repaired windows 7 using recovery CD.

Now my problem is that I can't reinstall Ubuntu 12.04 using Live CD it halts every time before disk partition step giving error.

"ubi-partman crashed". "ubi-partman failed with exit code 141. further information may be found in /var/log/syslog. Do you want to try running this step again before continuing? If you do not, your installation may fail entirely or may be broken."

and, any choice to continue will result in the same error.

I looked in to /var/log/syslog but not able to understand what is error.

Then, I ran sudo fdisk -l to view my partitions and it shows me only one partition. Probably, all the partitions I created for Ubuntu 12.04 are lost while running windows 7 recovery CD. So, I don't know whether the Ubuntu is still there or probably corrupted.

My boot-info URL is:

Please tell me how to remove this error so that I can reinstall/repair Ubuntu 12.04

Thanks in advance. R Shukla

Thanks for your help! I tried to boot from the CD but I every time it give me error before disk partitioning step. Also, I am unable to start Gparted.
