[SOLVED] ubilinux installer fails

Remon Lam

Hi all,

Perhaps I'm doing something totally wrong here but I can't get Ubilinux to install.
I keep getting the following error "No common CD-ROM drive was detected" (check attachment for a full error message).

What I did:

[ol]
[li]Followed the guide @ https://up-community.org/wiki/Installing_ubilinux_Operating_System[/li]
[li]Checked MD5 hash, seems to be okay[/li]
[li]Test 2 other USB drives, still received the error[/li]
[li]Tried CentOS and Fedora both failed to boot properly, tried it on a notebook and it boots just fine[/li]
[/ol]

Did I missed something?

Thanks!
Remon

Hi rlam8,

What utility are you using to flash the ubilinux image?

Remon Lam

I'm on OS X, so I'm using DD to copy the image over to the USB disk

Javier Arteaga

We hadn't tested OS X [tt]dd[/tt], but that should work. Are you following a procedure similar to this one?
https://wiki.archlinux.org/index.php/USB_flash_installation_media#In_Mac_OS_X

Does diskutil report a MBR partition table for your flashed USB drive?

Javier Arteaga

Confirming OS X dd can be used. We just flashed to a USB stick from a Yosemite system, and installed successfully from one of the USB 2.0 ports.

Remon Lam

Yep, it's the same;

To make sure it's completely empty;
sudo dd if=/dev/zero of=/dev/rdisk#

Than copy the image over to the USB disk;
sudo dd if=ubilinux-3.0RC3.iso of=/dev/rdisk4 bs=1m && sync

Unmount the filesystem;
diskutil eject /dev/disk4

Okay, I think I've solved my issue.

I used a 3 different 32GB USB drives they all failed with the error I described before.
When using a 8GB USB drive it worked!

Not sure why, but at least I've got it working now :-)

@jarteaga, thanks for your super fast support!

Javier Arteaga

Not sure myself, drive size shouldn't matter as long as the image fits. Anyway, glad it worked!

Remon Lam

Yeah that was my idea to, weird stuff :-D

Just dit a small test with Fedora and CentOS, same issue, 32GB drive failed to boot, 8GB just runs perfect.
Tested the same 32GB USB drive (both Fedora & CentOS) on a Minnowboard and it boots just fine.

Quick question what size of USB drive did you use?

Hi Rlam8,

I used a 1GB USB stick to flash the installer, but you can use any size without problems.

I have tested using different brands and size from 1GB to 16GB USB sticks.
