I have Arch Linux and Windows 7 on the same HDD (actually, it's SSD). During re installation of Windows 7 I have, by accident, formatted my /boot partition for Arch Linux. It's only 200 MBs, but as far I know I can't boot Arch anymore (not without /boot partition for sure).

Is there a way to preserve my Arch installation by, somehow, re installing only data from /boot partition? How to do it? Please help!

P.S. I don't know if it matters, but beside "/boot", my Arch has other partitions: "/", "/var" and "/home"
