grub problem after grub-repair
- by alireza
I had two OS,win 7 and Ubuntu, I was working with win and went out of the room and when came back I saw Grub Rescue!!! I booted live and did grub_repaire and it still says multiple active partitions.operating system not found
I feel that it can not find the ubuntu hard drive at all! !

someone said
{
Remove the boot flag from sda1, by typing in a terminal:
sudo fdisk /dev/sda1
Then press the 'a' key, and 'Enter'.
Then press the '1' key, and 'Enter'.
Then press the 'w' key, and 'Enter'.
}
but after grub-repair I got this log:
http://paste.ubuntu.com/1371297/
then I try
sudo fdisk /dev/sda1
and But It says unable to open /dev/sda1!
which is right as sda1 is not in dev folder (look at the picture!)
Can anybody help me? I need to work on my windows for the rest of the semester and don't care of my ubuntu. thank you
