Hi there,
I've got a 500GB external USB HDD attached to my Mac. Ive just partitioned it into two partitions; 863MB 'Install' and 499.03GB 'Disk'.
I downloaded the Ubuntu install CD image named 'ubuntu-11.10-desktop-amd64.iso'.
Ive got a spare computer knocking about, but access to no CD drive.
What I'm trying to do is get the install CD onto the 863MB partition so I can then dismantle the USB drive (already done actually) and then once the 'Install' partition is ready, move the HDD into the spare computer as a normal SATA drive and install Ubuntu from the 'Install' partition to the bigger 'Disk' partition.
Im attempting to follow the instructions for Installation from USB Stick here:
https://help.ubuntu.com/community/Installation/FromUSBStick
And have got as far as converting the .iso file to a .img file. The instructions now tell me I need to find out which device node my USB HDD has by using Disk Utility, then running the following command:
sudo dd if=/path/to/downloaded.img of=/dev/rdiskN bs=1m
(obviously I altered the command with respect to the location of the CD image file)
However, I cant see where Disk Utility tells me the device node of the USD HDD and furthermore I suspect that wouldn't help so much; I need to make a specific partition bootable, not the whole device.
Im fairly tech savvy but my knowledge isnt great when it comes to this sort of stuff; so if anyone can give me any pointers Id very much appreciate it. Perhaps Im following the wrong instructions or more likely Im too daft to understand :) But I'd still like to give it a go if possible.
I would've tried a network boot, but suspect setting up a PXE boot environment would melt my brain.
Thanks much
Dave
