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. 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

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.
