Hi guys I installed ubuntu 12.04 (x32) on my system and then side by side I had my windows7 ultimate(x64) running aswell (dual boot).

Last week for some reason I started getting a blue screen crash after running an update on ubuntu. Blue screen said it has a crash with code bCC:0000145, I didnt know what to make of it hence I thought just erase the whole HDD and start over with a fresh copy of windows. And this where (I feel a major disaster struck, as i'm a noob i've no clue what i did was WRONG!!!) I got into a huge problem, when I put in the Windows OEM cd and set the comp to boot from cd it was going all fine untill I deleted all my partitions into unallocated space and then wanted to make new partions and start fresh - BAMM another blue screen of death.

And this time after the blue screen it's stopped booting from Cd, and directly gave me an error message saying "no such partition; grub rescue" I've tried everything in my capacity to get it to work but I dont know clearly what to do further please help.

  • Just a thought: Start by not using capslock. – Thomas Ward Mar 22 '13 at 20:58
  • Did you try booting to an Ubuntu CD and try installing Ubuntu again? – Thomas Ward Mar 22 '13 at 21:02
  • no not yet!!! do you thing that will work with a flash drive??? – Ravi Krishnamoorthy Mar 22 '13 at 21:07
  • If you have another system that you can use to create a bootable USB on, then yes. [Read this page for details on creating an Ubuntu USB live environment from Windows](http://www.ubuntu.com/download/help/create-a-usb-stick-on-windows). You'll have to still have another system you can use though to do it. – Thomas Ward Mar 22 '13 at 21:08

    Note to everyone: If they can fix it by my comments, I will turn the comments into an answer. If not, then its part of the diagnostic process, so leave my comments be. – Thomas Ward Mar 22 '13 at 21:22
  • the lord thanks for the info... yes i do have access to another computer and creating a bootable usb – Ravi Krishnamoorthy Mar 22 '13 at 21:34
  • Might [TestDisk](http://askubuntu.com/a/176906/58950) launched from a LiveUSB be helpful to recover lost data? Or, perhaps it is too late now? – carnendil Mar 22 '13 at 21:38
  • You can insert the Installation disc again and then using repair my computer do recover your computer from an earlier time and then your comp is OK –  Apr 14 '14 at 03:16

Sounds like you installed grub on the master boot record.

You will need to run fixmbr or fixboot from a windows 7 recovery command prompt (located under repair my computer on windows 7 install disc). This will remove grub from the master boot record. You will then be able to re-install windows.
