Installing Debian 8 (Jessie) from HDD Partition

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.

I started out formatting my SDHC card to Fat32, putting the whole installer disk on it, making it bootable (does not boot). So I found the setup.exe on the DVD which lead me through the installation process. After rebooting, the installation progress starts and it tells me to either run an automatic search for a CDROM input or manually enter it -> nothing found

So I randomly guess around with tty3, 4 until I give up and run the shell.

With ls dev there is a list of possible drives. rtc0 looks nice, because my cardreader is an Realtek RTS5209. When I try to mount it, it says it is empty.

Now with lspci -v I found nothing usable for me.

So I made a new partition in FAT32 style, put the contents of the DVD there and mounted it using

mount -t vfat /dev/sda5/ /media/

Works like a charm, except that the installer does still ask for a CD / DVD source.

When I try to mount sr0 again, it says something about must be blocked device.
