When I boot up my Pi all I get is a solid red light, not the green one. I believe this is because the SD card is corrupt, but it was working fine the other day. I put the SD card in my windows PC and it can read the contents of the top level of the first partition (it should be ~40 files and a directory), but for some reason, the Pi still won't boot. Please help, as I have important files in my home directory on the Pi?
Thanks!
