Possible to run Ubuntu 10.04 64 bit with only a USB flash drive?

post #1 of 25
Thread Starter 
Hi,

I'd like to set up a folding farm using Ubuntu rigs, and was wondering if it would be possible to run Ubuntu from JUST a USB flash drive. If so, what is the minimum size I'd need? Other options?

Thanks

refer to steps 2 & 3 and I think you will be in business. probably 2gb as a minimum.

Technically you can, but a distro as bloated as Ububnu isn't the best option. I'd suggest you use something more along the lines of Puppy Linux or Arch Linux.

But if you're dead set on running Ubuntu, as long as you don't install many programs, an 8 gig flash drive ought to do it.

I think he's looking to do a frugal install to the flash drive, not just house the install disk.

Yes, it's very possible and very easy.

The way I would do it, would be to do it within Ubuntu because Ubuntu has a built in utility for making persistent USB startup disks.

Make sure you have the package, usb-creator-gtk (or kde if that you are running kde instead).

Then run the Startup Disk Creator found under Administration.

The rest is pretty self explanatory, just make sure you select "Documents and Settings will be Stored in reserved extra space". Put in the flash drive, select the image, and boom it does it all for you. Make sure that the image isn't corrupted, or it won't run properly.

I would recommend flash drives 2GB or greater, but it might be possible with flash drives that are only 1GB.

I think the live USB can save "progress".

The Live USB won't do it unless you've configured it right. Just copying the image to the flash drive will not make it persistent.

That means every time he restarts the computer, he will have to reinstall all the folding applications and reconfigure them every time. This I wouldn't do.

Hrmmm....guess I'll need to do more research. I guess using some cheap, 2nd hand HDDs off CL should be OK.

Yes, I was just suggesting using the USB as the main "drive" for the distro. The only programs would be F@H SMP/bigadv clients and GPU2/3 clients and HFM to monitor.

I don't remember it being that hard to configure, in fact, it was just a slider that allowed X amount of MBs to safe things.

If you have Ubuntu already installed on one of your computers, just do the thing I said above. It will produce a persistent Ubuntu installation on the USB.

You can do it in Windows, but I haven't had much luck with it (I don't know why, but it just wouldn't boot. It could have been that the ISO was bad).
