I am a total beginner to both Linux and Ubuntu.

I have a netbook, an Acer Aspire One D255 with Windows 7.

I want to boot from USB (no cd-drive on netbook) to first try Ubuntu and perhaps install it if it works fine.

I created a bootable USB (as shown on the Ubuntu website) , with Ubuntu Netbook Remix (10.10) I booted, and on startup, a purple screen with at the bottom a stickfigure in a circle and next it something (a harmonica? a chocolate bar? a strip of ram?) This shows for a second or 2, and then I get a black screen with a blinking cursor, and nothing happens after this.

Then, I created a bootable USB with the most recent desktop-version (11.04) It boots, it gives me menu, but if I press a key, everything freezes. When I don't press a key, it starts running from USB, and it does performs 2 loading steps and then noting... total freeze...

What is going on and what am I doing wrong?

Update: I tried waiting for 15 minutes but I still did not get a response.

Loading /casper/vmlinuz/.......

Loading /casper/initrd.lz............... ready.

looks like there is little knowledge of the usb-issue , 'cause there are a fair amount of question rgarding usb-boot and most of them are unanswered. – Natrium Jul 13 '11 at 5:54

How long have you been waiting? Boot from USB can be slow. – Lekensteyn Jul 26 '11 at 9:35
that chocolat bar is an accessibility icon :p It should bring you in a menu in which you can select accessibility options as well as other Live CD/USB tasks like RAM check. Some USB devices have a LED light to display activity, perhaps you're lucky too. Wait for about 15 minutes, it shouldn't take longer than that unless you've a USB 1.1 connector. – Lekensteyn Jul 26 '11 at 10:00
Can you try the usb drive in another machine? I suspect that it's something wrong with/in it. – Javier Rivera Jul 29 '11 at 15:44
