I already installed windows 7 in my laptop. Then, I installed Ubuntu 12.10 version alongside dual boot with windows. But, when i login into Ubuntu OS, it shows error like below :
system running in low config mode .
So, I started resolving that issue. But it worse. After solving the previous issue, again i got an error like below :
error: no such partition.grub rescue>
Then, I tried to repair ubuntu os through usb flash drive. It works, but after few times, I got an error like below :
error;unknown file system. grub rescue>
Again, I tried to install a fresh copy of ubuntu os using usb flash drive.
But, it doesn't boot even windows OS. My system is totally crashed.
I tried many ways by Googling,
How can I resolve this ?
(Note: I don't have CD/DVD drive in my laptop)
