I tried to install Debian 8 (Jessie) with the official DVD 1 from my Card Reader (SDHC UHS-I Card 32GB). Now that does not work, because I am unable to mount it (no signal at all).

Now I want to know if there is a way to install it from another HDD partition. I already made it FAT32 and put the files there, but the installer asks for a CD/DVD. Is there another installer that does take the files from the internal partition?

Also how do I remove the already started installation? I'm a bit straggled and can't find info about my problem.
