View Full Version : [ubuntu] 10.4 won't boot, blinking cursor.

May 16th, 2010, 12:58 AM
I decided to once again give Ubuntu a shot on my system.
But once again it's just ridiculous. :(

I boot from the 10.4 disc (64bit), it shows some keyboard icon and a background, then it just goes to a black screen with blinking cursor, and that's the end.

Motherboard: Gigabyte EP45-DQ6
Graphics: Geforce 8500GT

Any ideas?

Try that LiveCD on another computer.
Verify the MD5SUM/SHA256 of the ISO file.
Verify the LiveCD MD5SUM from the Menu selection.
Burn another CDR using different media, and at 4x and DAO (Disk-at-Once)

Install via Alternate CD.

I think this is your problem

Tried the disc on a laptop, and it works.

However, on this laptop there's all these fuzzy horizontal lines that keep moving around. Obviously it doesn't like this laptops gfx card.

But anyway, not worrying about the laptop it seems 10.04 like all the other versions of ubuntu is not going to work on my desktop pc.

You didn't give much info on your system there. Gigabyte and Gforce should work with linux quite well.

Have you tried the 32bit version?

Also even if the burned disk owrks on another computer doesn't mean it is burned propperly and that it won't "behave" with a more sensitive CD/DVD drive. It seems Ubuntu is more touchy about the burn quality than Win.

Try hitting any key when the keyboard shows. The language window will show then the boot screen. Use ext 4 for your OS.

Also try pressing any key at the purple screen with a keyboard and stickfigure to get to the menu. Select your language, and then hit F6. Choose "nomodeset". If that doesn't work, try some of the other options in that popup.

Tried everything suggested.
Same crap, with just a blank blinking cursor.

At the menu, F6 and then Esc to edit. Remove "quiet splash" and replace it with "xforcevesa noapic noapci nosplash irqpoll". See if that works.

Edit: Also, you really should select "Check disc for errors" at the menu. If it's giving you problems on two different machines, I think it's very likely that something's wrong with the CD.

The laptop booted though anyway my canonical copy just came in the mail. I'll try that, and what you suggested.

The laptop booted though....

You mean the one that gave you screen corruption when you booted it? :P

Hence why I thought there might be something wrong with the CD, since it doesn't work correctly on 2/2 computers.

Well, I tried the canonical disc.
Exact same problems.

I tried to verify the disc, it just went to the same bloody black screen with blinking cursor.

Tried that.

Got these messages, then it stopped at the dreaded blinking cursor again.

Well that's why it won't boot. You're getting a kernel panic. But "No filesystem could mount root..."?? That's either a corruption in the CD or a genuine kernel bug.

You really need to check the MD5SUM of the original iso you downloaded.
If you could check the actually two CDs you tried that would be best.

If they're both fine, then you need to file a bug on launchpad against the "linux" package.

May 23rd, 2010, 04:12 PM
Checked out fine (well the iso I tested).

I didn't know how to test the CD.

How do I report a bug?

Does any other version of Ubuntu work on your computer? An old LiveCD even? You really need the output of

lspci -vvnn
Then file a bug against the linux package here:
and attach the screenshot above and the output of lspci -vvnn. And a clear and detailed description of what the problem is and what you've tried in order to fix it (i.e. checked the MD5SUM and used multiple disks).

No, Ubuntu hasn't ever worked properly on this system and I've got all the way back to 8.10.

Every new release I try, but find it's still the same ********.

Not sure how I'm supposed to get the output if I can't boot either. Any other ideas man?

You can see if you can get the Alternate CD to install:

That should install Ubuntu onto your machine; that way you can test if it's an issue with the live session or the kernel itself.
