    I found the solution. The floppy controller is disabled by default. For someone who encounters the same problem:

    1. close the guest OS
    2. Go to the settings of the guest OS ( to which you want to add the floppy image)
    3. select “Storage” from the right column
    4. now add a floppy controller ( find a button with a green plus sign and a tilted white rectangle in background)
    5. now add an empty floppy drive under it.

    Done:) now follow the video as usual!
    Thanks for such a nice video Tinkernet!

    I think the video is messed up cause its not the right one. the one that is showing is the one for the 3d picture printing. not the operating system. repost or something?

    you have done a great job!. This tutorial was a boost up for me like beginners.
    I would be even more happy if you release a video tutorial of Assembly Language
    for beginners. Though there are many reference articles regarding this , but a nice video will be more effective ,specially for those who are visual learners.
    Please please please , do keep this small request. It would of great help to me.
    It will help to learn Assembly Language easily. Thanks once again.

    Hi Gigafide ( Tinkernut) can you please help me with my OS because everytime my OS tries to boot in virtualbox I get an error saying kernel.bin not found and I am so close to booting it. Today is the second day that I have tried to get the OS to boot it is a pain in the buttocks.

    I had trouble writing the kernel to the floppy. (BTW, i’m using real floppy disk with xp). After I wrote the bootloader to the disk, it said it was write protected. Then i went to windows explorer it said it couldn’t open it’s file system or format it. plz hlp!
