Classic black screen issue on boot: Version 10.10

Asked by Pierre-Louis Guidez

Hey guys,

I'm completely new to Ubuntu and I'm fairly noobish compared to most of you. Here's the deal. I'm trying to use ubuntu from my 8GB flash drive. To boot, I used the advanced BIOS setup (i think it is called) to boot from the usb instead of booting windows. NO, i don't get a man with a keyboard, it just skips right to the menu. From there, it starts booting after 5 seconds, I see "UBUNTU" with 5 little dots underneath progressively flashing, then it goes back to typing random crap, and then nothing.

Please help me, this is a pain, and please explain clearly, I have tried multiple solutions, without really knowing what a kernel or a grub are.

What I see. (I only put what I thought could be a problem)

1) A bunch of "controller is probably using the wrong IRQ" and "failed to..."
2) The Ubuntu screen with the dots under it
3) "Unable to find a medium containing a live file system"
4) a. found new high speed device, using ehci_hcd and adress 11
    b. not accepting adress 11 -110
5) a. found new high speed device, using ehci_hcd and adress 12
    b. not accepting adress 12 -110
6) ETC.... unttil "Controller is probably using the wrong IRQ"
7)Long wait
8) "Found new full speed USB device" (notice the "full")
9) "Kernel Thread helper...."
10) LONG WAIT then monitor doesn't display anything. Hope this will help

PS: I checked, it is the right ISO

Did you check the iso download with md5sum?
Sounds like the 8G stick is created as a live-media Ubuntu instead of an install to an 8G stick from another live-media, so you either have a lot of wasted space on it or you selected the RW part to be larger than the default of 128M -- This larger size seems to cause many problems. I'd suggest partitioning the 8G stick into a 1G partition for the install media with minimum rw, and 7G for creating the rw as a partition with a filesystem labeled casper-rw instead of having a file named casper-rw. I don't put a swap partition on these s ticks myself, but if you need to hibernate, add a swap partition. Your boot time on such a stick will be about 3 min, but performance once things are running will be pretty good. I've even updated such a stick successfully.
