ubuntu 11.10 cdrom/dvd unable to mount
Hello All
I'm running Ubuntu 11.10 which I installed on a Flash drive. Ubuntu was installaed using virtual box on a notebook which as you know does not have a cdrom/dvd. I was able to install ubuntu just fine and it runs awesome booting from the usb. The only problem I have is that when I use ubuntu on a computer that has a cdrom/dvd it won' t mount. I'm assuming this is happening because when I installed ubuntu using notebook the installation didn't bother configure it to mount a cdrom/dvd since I did not have one. I did some research and in order for my cdrom/dvd to work I need to add something like this /dev/sdc0 /media/cdrom0 iso9660 ro,user,noauto 0 0 on /etc/fstab file. However I dont see any sdc0 file under the /dev folder. Can someone guide me on how to fix this issue? Thanks a lot |
Hello,
If you do a 'ls' on /dev do you see a symlink named cdrom, cdrom1, dvd, or similar? Is so what is it pointing to? Kind regards, Eric |
Nop I dont
|
how can I know where is it pointing to?
|
On my debian system, its sr0, I would imagine Ubuntu is likely to be the same.
|
sr0 is not under /dev either. :(

Hi,
Can you post output of this also: Code:
ls -l /devKind regards, Eric |
Looks to me like no CD drivers are installed.
