I installed fedora 9 on my lenovo laptop which was preinstalled with vista basic.Now I dualbooted It.Today when I choose to boot vista from boot menu
it only shows me
"rootnoverify,chain loader+1"
I unable to boot vista.
So I booted into fedora to check wheather any problem occured .
When I tried to mount c drive which was preinstalled vista it show error like this
"Failed to mount /dev/sda1:input/output error.1>NTFS is either inconsisent or 2>you have hardware faults,or you have a softRAID/FakeRAID hardware.
In 1st case run chkdisk /f on windows then reboot into windows twice.The usage of /f paameter is veryimp.
In 2nd case if u have softraid/fakeraid then 1st u must have activate it & mount a different deviceunder the /dev/mapper/ directory,plz see dmraid"

So is this the h/w problem or os problem or anything else ??
Plz suggest me what'll I do ,If I am formatting it ,I've to backup my data from that drive ,Is that possible from fedora ??

I believe the above should be something like this:
Provided you have Vista installed onto the first partition.

Try this and see if you can boot into vista.

trying ..

no still not booting

What is the error you're getting now ?

You mean back up your data from Vista partition ? Not unless you're able to mount that partition in Fedora.

What kind of laptop and hard disk setup do you have there ? Could you post the output of "fdisk -l" without the quotes ? Also, post the output of /boot/grub/menu.lst (it maybe /boot/grub/grub.conf or /etc/grub.conf in your case).

EDIT: Damned ! I only clicked "Post Quick Reply" once ! It got posted twice !!

output of fdisk -l:
