hi, i have installed fedora 12(from dvd) on my laptop having window 7 OS as deafult(intel processor i330)
I wanted dual boot up, so I shrink the existing C partition using window using Disk Management. And then delete the newly created volume.
And install feora 12(64 bit) with option "using free space".
Clean installation of fedora.

But when I tried to boot window it is showing "No C drive exist".

Although from linux all hardrive is coming as one file system and all data on Drive are intact i.e not data is lost.

I have tried twice with same result.

Is there any issue with new type of processor?

anybody have idea why its happening like this and how install fedora keeping Window 7 as well(dual boot).

In Fedora do

#su
<root passwd>
#parted

>print all

use gparted or qtparted to make sda1 bootable

and

#su
...
#grub-install /dev/sda

here is the output of the command parted:

Hi Amani... Thanks for your support.
Problem is now fixed by replacing
title Other
rootnoverify (hd0,1)
chainloader +1

in grub file with

title window7
rootnoverify (hd0,1)
makeactive
chainloader +1

now window is able to boot up and linux is also working fine.
