Help making bootable USB

[gravitate]

I am trying to make a bootable USB with my mac for a windows netbook which I am going to wipe and put ubuntu on. However I am trying to convert the .iso to a .img and keep getting this:

pc3:~ liteaddress$ hdiutil convert -format UDRW -o ~/Users/liteaddress/Downloads/ubuntu-12.04.3-desktop-i386.img ~/Users/liteaddress/Downloads/ubuntu-12.04.3-desktop-i386.iso
hdiutil: convert failed - No such file or directory
pc3:~ liteaddress$

Any ideas please?

[sanderj]

Do it the easy way:



cd ~/Users/liteaddress/Downloads
pwd
ls ubuntu-12.04.3-desktop-i386*
hdiutil convert -format UDRW -o ubuntu-12.04.3-desktop-i386.img ubuntu-12.04.3-desktop-i386.iso
ls ubuntu-12.04.3-desktop-i386*


Post the output here.

PS: I wonder if ~/Users/liteaddress does exist. Don't you mean ~/Downloads? Anyway: change to the directory containing the .iso file.

hdiutil: convert failed - No such file or directory
pc3:~ liteaddress$ ls ubuntu-12.04.3-desktop-i386*

[gravitate]

sorry it should have been /Users/liteaddress/Downloads I'm a bit lost now

[gravitate]

I go to get info and it says where: /Users/liteaddress/Downloads


Name and extension: ubuntu-12.04.3-desktop-i386.iso

[sanderj]

I'm lost. Did you find ubuntu-12.04.3-desktop-i386.iso ?

If so, do this: go into that directory and type:


ls -al ubuntu-12.04.3-desktop-i386*

and post the output here.

[gravitate]

pc3:~ liteaddress$ ls -al ubuntu-12.04.3-desktop-i386*
ls: ubuntu-12.04.3-desktop-i386*: No such file or directory
pc3:~ liteaddress$ ls -al ubuntu-12.04.3-desktop-i386
ls: ubuntu-12.04.3-desktop-i386: No such file or directory
pc3:~ liteaddress$

[sanderj]

pc3:~ liteaddress$ ls -al ubuntu-12.04.3-desktop-i386*
ls: ubuntu-12.04.3-desktop-i386*: No such file or directory
pc3:~ liteaddress$ ls -al ubuntu-12.04.3-desktop-i386
ls: ubuntu-12.04.3-desktop-i386: No such file or directory
pc3:~ liteaddress$

So ... there you have the problem: first you have to find ubuntu-12.04.3-desktop-i386.iso on your system.

Wait ... you did download it, didn't you?

EDIT: if you need to download, do this



cd
curl -O http://ftp.belnet.be/ubuntu.com/releases/releases/precise/ubuntu-12.04.3-desktop-i386.iso
ls -al ubuntu*

[gravitate]

Yes its in my Downloads folder I right clicked it to 'get info' and thats where I get this info from of the where:/Users/liteaddress/Downloads

And Name and Extension: ubuntu-12.04.3-desktop-i386.iso

[sanderj]

Yes its in my Downloads folder I right clicked it to 'get info' and thats where I get this info from of the where:/Users/liteaddress/Downloads

And Name and Extension: ubuntu-12.04.3-desktop-i386.iso

Then show me with the the "ls -al ubuntu*" command. If you can't, the file is not there.

[gravitate]

I will download it again :)

You are in the wrong directory.
Your are using the ls command in your ~ (home) directory.
The file isn't in that directory.
The file is in your ~/Downloads directory.

Either cd into your Downloads directory or ls the Downloads directory.
Examples.


# I have a file named 'hello' in my Downloads directory

# Look for it without changing directories

ian@bot:~$ ls -al hello # Doesn't work - hello isn't in that directory
ls: cannot access hello: No such file or directory

ian@bot:~$ ls -al Downloads/hello # Works
-rw-r--r-- 1 ian ian 0 Nov 25 15:34 Downloads/hello


# Change directories

ian@bot:~$ cd Downloads/
ian@bot:~/Downloads$ # The prompt shows where I am. I have moved.

ian@bot:~/Downloads$ ls -al hello # Look for hello in this directory (success)
-rw-r--r-- 1 ian ian 0 Nov 25 15:34 hello

ian@bot:~/Downloads$ cd .. # Return to home directory
ian@bot:~$

I went to Downloads and did your command but the command was not found:

pc3:Downloads liteaddress$ ls: ubuntu-12.04.3-desktop-i386*
-bash: ls:: command not found
pc3:Downloads liteaddress$

[sanderj]

will you be around for 10 mins to help please?

Yes. What is the result of the command I gave you:


cd
curl -O http://ftp.belnet.be/ubuntu.com/releases/releases/precise/ubuntu-12.04.3-desktop-i386.iso
ls -al ubuntu*

[ian-weisser]

The ls command does not have a colon. You made a syntax error...and the system told you so ("command not found")

Please use [code] tags for your output. It helps make the output readable.

[gravitate]

Thanks though I understand it now but why is ls:: command not found?

[gravitate]

OK no errors now :)


pc3:downloads liteaddress$ ls ubuntu-12.04.3-desktop-i386*ubuntu-12.04.3-desktop-i386.iso
pc3:downloads liteaddress$


That means its there right?

hdiutil convert -format UDRW -o ubuntu-12.04.3-desktop-i386.img ubuntu-12.04.3-desktop-i386.isols ubuntu-12.04.3-desktop-i386*

[gravitate]

I don't think so.

In your case I would give up this route. Go for unetbootin (with GUI) instead: http://unetbootin.sourceforge.net/, possibly from Windows.

[sanderj]

wooow nearly there now

Not at all, IMHO: I still see no *iso and you still have to do the dd which is much harder.

Therefore my advice to use unetbootin.
