I'm using a bootebale USB with Kali Linux Kde 64 Bit 2018.3 on a 16gb Toshiba Pendrive.
I made the live booteable unit using the lastest version of the Universal USB Instaler software.
I can run the live CD without problem from the USB. When i try to install it directly on the computer, is asking me for a CDROM.

I search around the web and tryied the next:
Open the terminal. ALT + F2.
List my USB device. BLKID.
Make a CDROM folder. MKDIR /CDROM.
Mount the USB on the CDROM folder. MOUNT -T VFAT /DEV/SDBX /CDROM.
Check the files inside the /CDROM folder. CD /CDROM. LS.
Back to the Interfaz. CONTROL+ALT+F1/F5
Try to dectect the CDROM again. Plugout wait and plugin the Pendrive several times.

Nothing worked so i decided to use other software to make the Booteable USB.
I used latest version of RUFUS and repeat all the process.
Still having problems on the Mount/Load files from CDROM step.

What i want is to install Kali Linux Distro on my HardDriveDisk using a booteable USB, becuse i have no way to burn a CDROM.
Is there any log file what i can check to post it?. Thank's for your time.
