First day using linux, can no longer boot


I just built a new PC and installed ubuntu 11.04 on it, and everything was working fine. i was trying to set up the drivers for my wireless adapter, so I ended up blacklisting one of the ones that comes with 11.04 and then rebooting. Since powering down, i haven't been able to get past a black screen in the typical boot (flashing _ for 10 seconds then black screen) and in the safe mode boot i get to some script and it doesn't go any further. I'm sorry for being an ultimate noob, I'd just like to be able to boot again!

p.s. i also tried to recover my system from the 11.04 CD, however i'm not sure what you have to do in that ( I was unsuccesful in my two tries with it).

Hi Xylem, welcome to LQ,

it seems that you blacklisted a module for your graphics-adapter instead one for your wireless-adapter.

You should try (when you've booted the 11.04-CD) to revoke the blacklisting of that driver. Looking at this https://help.ubuntu.com/community/Wi...er/Ndiswrapper site you see, that the blacklist-file resides in /etc/modprobe.de/ you should edit the blacklist-file and delete the line with this driver.

And before making your system unusable, please tell us which wireless-nic you have. BTW, it is never necessary to reboot Linux when installing drivers.

If I were you I'd put this down to a learning experience and start from scratch again. I'd do a clean install and once you have done that run the command
Code:
sudo lspci
in a terminal and post the output of the command here for us to see. Once you have done that we can help you to work through your wireless issues. Also doing it this way means we only have to work through 1 problem not 2.

I'd also be starting with a newer version of Ubuntu. 11.04 only has 6 months support left so I'd be considering 11.10 (has another year of support) or 12.04 (has 5 years of support). You may also find a newer version works straight away. It is, to me anyway, worth a try.

Not totally accurate, I have an older laptop that I always had to reboot so ndiswrapper would work.

Also, Ubuntu 12.04 is just released now, so I doubt that 11.04 will be getting updates for much longer (if it hasn't already been shut off). I'd suggest moving to 12.04; you might get lucky and find that your wireless NIC is supported automagically in the newer distro.

Thank you, however I cannot figure out how to actually boot into the live CD, it gives the options of Memtest, Install 11.04, Boot from HD and Recover system.

I was trying to get a DWA-160 wireless USB adapter to work, however i've been finding lots of guides saying vastly different things... Unfortunatly i followed one of their suggestions and it obviously left me in a bad spot. In general, I have no idea what I'm doing.

Since I haven't actually done anything with my computer should i just re-install? I don't know...


P.s. i thought linux would be a fun way to get to know my computer better, but i'm beginning to realize there is A LOT to get to know..

woah, thanks all for the posts. Yeah, the problem i was trying to avoid was that i wasn't sure if 12.04 would be able to support my system, and that 11.04 would have had more troubleshooting time (since 12.04 just came out). But i guess 11.04 probably isn't any better. I also got irked because on the ubuntu website the automatic download is for AMD processors and i have an intel, after downloading it and burning the cd i was like.. damn what a waste of 3 hours...

That's the architecture amd64 = x86_64 which you can install on any 64bit system (also Intel). Most recent processors are 64bit.

You should when you've booted the installer-CD open a terminal and post the output of
Code:
lsusb
Code:
lspci -k
Code:
lsmod
be sure to have the Wlan-stick plugged in. With this output we can see, which hardware you have, which hardware is already supported and what to do to get wireless working.

i have the iso on a disk, and i get the main screen when it loads, but any option goes straight to black screen... so i assumed that was the problem.

Which processor does the computer have?

It's more likely to be an issue with your video card. You might want to try the alternate install CD to see if you have more like, although it can be a bit more daunting for a newbie. In general, with Linux it's always best to go with the latest release, as many bugs and problems get fixed between versions, and new hardware support gets added. There are some exceptions to this rule, but when just starting out, it's better to have the latest and greatest.

Yeah download and install Ubuntu 12.04 LTS 64bit. If it says AMD is fine is just the label but will run good on your hardware.

The wireless thing you want to make work with ubuntu is not the onboard wireless card right? is an adapter you had bough for your desktop?
For a while I used one of these netgear USB wireless adapter and worked well but nothing will beat hard wired connection for speed, so I bought 15 feet of CAT6 cable instead.

Good luck to you!

It's an intel i5 2500K cpu, ASRock Extreme3 gen3 motherboard
with Nvidia GeForce GTX550 Ti graphics card. I know theres lots of issues with both integrated intel graphics and graphic cards.. but yeah, if my computer won't allow me to install 12.04 (the version from the website), what should I do?

What's the difference between you install-CD for 11.04 and 12.04, how did you get the 11.04-CD did you burn it? if so, you should have done it with the 12.04-CD the same way. As you know, you'll have to burn the iso as an image, not as data.

Your hardware should be fully supported by 12.04. You can use the amd64-version without any problems.

They're both isos, I guess the 11.04 was an alternative download for intel processors, whereas the 12.04 is the iso off the ubuntu website. I think I'll try burning an iso of the alternative version from here :
http://cdimage.ubuntu.com/daily/current/

should I go with the Intel one?
