Troubling mounting and installing ParrotOS
 

Hello everyone,

I recently downloaded ParrotOS and made a live usb from within MXLinux. I am able to boot with it as Live media, but when i try to install, it gives an error of CD-Rom not found. I found a solution to mount USB as CDROM from shell, during installation, but i am not able to mount it.

USB is /dev/sdb and i am trying to mount it as follows

This gives an error, so i tried mounting sdb2

It mounts, but this partition doesnot has the installation files, hence i cannot install.

From within linux, sdb1 can be mounted and used.

What am i doing wrong??

"this gives an error" what error was that?

mounting on /cdrom failed: Invalid argument

probably it is already in use, try another mount point (/cdrom1)

if it was, then i wouldnt have been able to mount sdb2 on it

in that case /dev/sdb1 is not mountable. Either it contains no usable filesystem or corrupted.
You can also use mount -v, probably give more info and check the return code too (see man page). You may check /var/log too.
Try gparted or any partition tool to check it.
