Linux wont boot, error:no such partition? Edit
I have accidentally deleted and formatted my linux partition and now my computer wont even start windows (multiboot). When I start my pc it shows error:no such partition and it enters rescue mode. It doesn't know any commands because i deleted the system, and when i try to boot windows partition from there it says unknown filesystem. I tried booting from usb but it ignores it for some reason although I have usb as number one boot option. I don't have any windows boot cd's or something. What can I do to at least boot windows again?
