7 is not working after dual boot with ubuntu

i have dual boot windows 7 with ubuntu, but after that ubuntu run well but it is not displaying any drive. then i restart windows,
it shows 5 boot option 2 of ubuntu, 2 of memtest, and 1 of windows 7 loader(on\devsda2\) something. when i click on it
it shows 2 option:
1. launch startup repair
2. start window normally
when i click on " start window normally" it restart after displaying a blue screen for 1 second.
launch startup repair is also not working.

then i finally decided to start a fresh copy of windows 7, but on partition manager it shows no drive when i boot it from windows 7 DVD.

Hello vikrantsjs.



The first thing to do would be to make backups of the data you need to save to external media using the method out-lined in this tutorial at the link below, it works very well, I've used it myself.

Copy & Paste - in Windows Recovery Console

i dont want to recover my data of my c drive but i want that the data of my other drives remains safe, hope u understand
by the way when i click on load drivers >my computer,

then it show me a partition named X. which is only of 31.5 MB.

help me.

Boot from the Windows DVD and Select Launch Startup Repair.

If it still doesnt work then, Boot from the windows DVD and enter the recovery environment.
Open command prompt and type the following commands.

Code:

bootrec /rebuildbcd
bootrec /fixboot
bootrec /fixmbr

Remove the DVD and restart your computer.

first command run successfully.
when i run second command it says
"THE VOLUME DOES NOT CONTAIN A RECOGNIZED FILE SYSTEM.
PLEASE MAKE SURE THAT ALL REQUIRED FILE SYSTEM DRIVERS ARE LOADED AND THAT VOLUME IS NOT CORRUPTED."
when i run 3rd command it run successfully.
now tell
