My Dell Mini Forum

I've tried creating a DVD with dellminiboot123.iso... It doesn't boot. It just reverts to Windows. I've tried creating a bootable USB drive.... It doesn't boot. I get a message saying the operaing system can't be found. I must be doing something monumentally wrong. Any clues would be much appreciated.

Reset the bios to default settings. Reboot. Go back into the bios and change the default boot order and you should be able to boot.

Did you actually create an iso? My first attempt at creating one with Toast didn't work, when I made one using disk utility it worked.

Yeah this got me too as a newb to OS X. Coming from the XP world I didn't understand that there was a process to create an iso. It isn't just dragging the file to a cd (at least not in XP). Is that the issue?

An ISO is a file representation of a physical CD. Bootable is in the ISO, and your burning software must burn an ISO image to a disc. Putting the iso image as a file on a disc is doing it wrong.

Edit: After you are sure you have burned a bootable disc from the Type11-iso132 (try booting from that disk on your desktop computer to verify the disc)....I have found the Mini acts weirdly when booting from my external optical drive. Mini ignores the USB extrernal DVD drive for several boots, battery pulled and power cord too between each boot. Mini will check CD drive then ignore it over and over, then something gets traction and it boots every time thereafter from the optical drive.

And I thought that I was the only one having that issue! It drove my crazy when I installed the first time.

This was the big hold-up for me too until I finally got it right.
This might help.
