I realize that this is a duplicate of a question asked before, but in that question the asker managed to find his live CD and no real answer appeared, thus I am re-asking it.
I managed to screw up my GRUB by deleting two linux partitions on my hard drive from windows. After this, GRUB gives the error "partition not found", and gives me the grub-rescue> prompt. The only command I have found to work in this is 'ls', which spits out my partitions. I would use the live CD fix, but I am in India, and all my live CDs are back home in the US... What I've got is an internet connection, a 4GB flash drive with Flow OS installed (which I am currently using but can wipe if need be), and a working laptop that I can borrow. What should I do?
