Hello together, it seems you are all thinking way too complicated. As I suggested in the other thread, I'm just gonna post a little howto.
So, here it goes: 1. Booting from USB flash, USB hard drive, or internal hd, is basically all the same. You first need to install grub2 on it. If you already have a running system with grub2 on the hd you want to boot the installer from, you can skip this step. Let's assume your to-be install partition is /dev/sdb1 (file system should not matter, can be fat32 on USB for example, or any fs linux supports). You don't need to format this partition. For example mount it as /media/install. Install grub2 (as root) with: # grub-install /dev/sdb --root-directory=/media/install This will install grub into the MBR of sdb, which you will later use your BIOS boot menu to boot from, and create a folder /media/install/boot. 2. Now copy the .iso, or since there's this problem I encountered (http://lists.debian.org/debian-user/2013/05/msg00291.html) it's easier to unpack the contents of the iso to /media/install/debian_iso 3. Edit /media/install/boot/grub/grub.cfg and add the Debian installer entry. If you use your current system's grub, add it to the very bottom. (In this case, any update-grub, i.e. from a kernel-update of your running system will overwrite it again) The entry should look like this: menuentry "Debian 7.0 wheezy installer, x86_64" { linux /debian_iso/install.amd/vmlinuz priority=low vga=788 -- initrd /debian_iso/install.amd/initrd.gz } 4. Shutdown, press your BIOS boot-menu key (F10-F12 on most machines) and select the disk that was /dev/sdb before. The Debian installer should come up, you can select language, locale and stuff and it should "fail to detect the CD-ROM" at some point. 5. Now Press Alt+F2 and Enter to get into Busybox's shell. Mount your installer partition (careful, it might not be /dev/sdb1 any more, check with ls /dev/sd*) # mount /dev/sdb1 /mnt Make sure it is the correct partition # ls /mnt If there is no debian_iso in there, try another partition. 6. Now bind (or symlink) the debian_iso folder to /cdrom: # mount -o bind /mnt/debian_iso /cdrom 7. Press Alt+F1 to get back into the installer. Choose the step "Load installer components from CD". 8. From here on, the installation should proceed normally. I hope this helps! Have fun and good luck! If you run into problems or have any more questions, reply to this thread and CC me to make sure I notice.
