CD-ROM is not detected in Debian USB installer

readme

Recently, I was installing Debian from USB Drive. You know nowadays nobody want to use cd-rom.. I remember past years installing floppy disk…. after from cd-rom….but it is either USB or PXE. It is very easy and fast. So, back to the subject, I use the software Unetbootin to create a USB image. It was working well with others versions of  Debian. I boot with USB and the installation was going well when suddenly I get error saying the CD-ROM is not detected and unable to continue the installation.

After few trick and research, I found the solution.

Version used :

    Debian version 6.0.6 Release 29 Sept. 2012
    Unetbootin version 5.75

First of all, in your debian installation, got to console mode :

    ctrl + alt + F2

You can use F1 or F2 or F3 ….use which one not in use. After that, the mount the USB drive in FAT file system using the command below.

    mount -t vfat /dev/sdb /cdrom

Where /dev/sdb is your USB drive
And /cdrom is location where you want to mount

And then, go back to graphic mode

    ctrl + alt + F5

In my case, the graphic mode use running on TTY5, It may be different for you. Now, you can continue your installation

After I went to UnetBootin website, I found that they also release an update version 5.81 on 6th Sept 2012 Info. I do not know if that update fix the problem. One way to find out is to try.

After that, the installation should work without any other problem. Let me know if this tips was helpful or not.
