Can't detect CD-ROM

Can't mount CD in the installer.

I'm using a USB bootable and selecting graphical installer. No matter what I do, change the USB drive, re-download the ISO it always displays the error "can't mount CD-ROM", or can't "can't detect CD-ROM". However, the live session works fine.

My PC is an i5 2400 at 3.10 GHZ with 8GB RAM and 1TB hard drive.

Weird, isn't it?

Re: Can't detect CD-ROM

how did you create the bootable CD?
I believe the bunsenlabs site has instructions for that.

Re: Can't detect CD-ROM

I did it with using Rufus, in Windows 10.
Was that bad?

On the Bunsenlabs download page are links to instructions...

How to write an ISO image

Rufus should be OK, AFAIK

Re: Can't detect CD-ROM

None of these programs offer an option to burn to a USB.
I don't have a CD-ROM or DVD drive.

Re: Can't detect CD-ROM

^ interesting username.
that will really inspire people to help you.

everytime you say that something is "broken" on linux, you basically say that you know better than a bunch of devoted developers.
always better to state the facts, e.g. "this didn't work for me", instead of making broad statements.
it's also more optimistic; it includes the chance of fixing: something that didn't work, might be made to work next time - nota bene: by your effort, not by demanding a fix.

There is a link to https://sourceforge.net/projects/win32diskimager
That program for Windows is "designed to write a raw disk image to a removable device or backup a removable device to a raw image file."
Try it!

Re: Can't detect CD-ROM

FYI in case anyone else sees this same issue (unable to detect CD-ROM):
  like dany above I had also used Rufus to write the .iso to USB, and chosen the default/recommended Rufus option of 'ISO' write method/format.  So I went back and re-created the USB using the other Rufus option ('DD' ), and now Helium install detects CD-ROM OK . yay! :-)

I'm unclear on the difference between the 2 options, but I suspect this thread probably doesn't belong in the bug report section..
cheers

Re: Can't detect CD-ROM

I ran into this problem yesterday installing Lithium. Googled it. Drop to shell after the CD is undetected and:
$ mount -i vfat /dev/sdb1 /cdrom
$ exit

And start from "Detect CD...

Worked for me.

Maybe appending this line to the appropriate install script might fix the issue...

Re: Can't detect CD-ROM

I had the same problem.

Just put the pen drive out when the error is shown and then put it back in.

Hope it work for you.

Re: Can't detect CD-ROM

I was installing Lithium and had the same issue like OP. I followed @paracas advice and it worked.
So if anyone is using Rufus to make a bootable USB drive, you have to choose the "DD" type of writing onto USB for it to work.

Re: Can't detect CD-ROM

Hi

Posting in case this could help someone at some point ...

Trying to install BL lithium on a new SSD drive from an SD card and the installer cannot detect my cdrom...

None of the solutions above worked out for me:
- burn image with Rufus in DD mode (Rufus 3 does not show the option in the interface anymore, a prompt will show up when you launch the process)
- burn image with win32disk imager
- "mount -i vfat /dev/sdb1 /cdrom" command in a shell

Here is what worked out for me (from https://superuser.com/questions/962926/ … -rom-drive)

After the error shows up, go back to the installer menu, and launch a shell (the before last option); in the shell, type

~ # blkid

in what is returned, identify your ssd; mine was /dev/mmcblk0
(p1, p2 ... will indicate the partitions on the device so if only partitions are returned, e.g. mmcblk0p1 & mmcblk0p2, you can guess the name of your device will be mmcblk0 if you omit p1, p2...)

then "mount" your cd rom by typing:

~ # mount -t iso9660 /dev/<your device> /cdrom

so for me, it was actually

~ # mount -t iso9660 /dev/mmcblk0 /cdrom

("the issue is the file format is not vfat, but iso9660")
--> the cdrom should now be mounted

exit the shell

~ # exit

Back to the installer, start from detect cdrom option et voila ! The installer resumes

--> @admin: something to improve in the installer for the next version thanks
