Unknown filesystem on Lenovo B460e laptop

Question

I got a Lenovo B460e laptop yesterday (given by the Tamil Nadu Government). It has Windows 7 Pro on it.

I set it up the way I liked it. All software drivers and all. I wanted extra drives, so I entered the Windows diskadmin and changed my partition setup by splitting. I did the partition setup in the installing process, so I split my harddisk into 4 parts. So far so good.

When I rebooted, I entered GRUB Rescue Mode. In this mode I know the only command ls. Which returns something like:

(hd0) 
(hd0,msdos5) 
(hd0,msdos4)  
(hd0,msdos2) 
(hd0,msdos1)

This laptop does not have a CD drive, otherwise I could have formatted the OS and installed a new OS using Windows 7 CD. Now I don’t know what I’m supposed to do.

Any idea on how to fix this?

Solution

If you have another computer, you can download the Windows ISO and boot an USB drive from it.

Now you can install Windows 7 onto it.

Some additional info on this system seems to be here. These seem to dualboot out of the box, which explains why it has grub, and boots windows 7 and "Boss" linux, which i have never heard of before.
