Follow the steps below to fix 'Detect and Mount CD-ROM' error

First solution: 

1. when the Window shows CDROM couldn't be mounted: unplug your USB from system, wait 10 seconds and re insert it

2. Wait for mount/ detection (USB LED glow).

3. Click 'Yes' to retry mounting the USB / CDROM

4. Hit Continue

Second solution:

1. Run the installer.

2. Open a shell (ALT + F2).

3. Create the directory cdrom directly on the root of the file system:  mkdir /cdrom  mkdir /cdrom

* Note : If you got problems making the directory /cdrom, disable the CD-rom player in BIOS or disconnect the cable

4. Mount the USB as if it is a CD-ROM: mount -t vfat /dev/sdb1 /cdrom  (Where sdb1 is your USB device).

You could carry on installation now

* After executing mount -t vfat /dev/sdb1 /cdrom, cd into the /cdrom directory and do an ls to see if the files are there. Then press ALT-F1 to go back, continue and re-select "detect CDROM" 

Third solution:

We need to create the USB using DD mode instead of ISO.

This is our last priority because it will make the USB unusable, however If you were not successful with the first two solutions please contact us via this page, or by email:  and we will send you a DD mode USB.
