“Kernel error, try with noapic option” displayed when installing Ubuntu
I'm sorry if this has been mentioned before, but I couldn't find anything on google about my specific error, so here goes...
I've earlier prepared a live USB via UNetBootin with ubuntu 12.04 (64-bit) and could use it to both run ubuntu from the USB as well as installing on my laptop, which I did a few days ago.
The laptop is a Lenovo R500 running 64 bit Windows 7 (and now also Ubuntu)
However when I try to do the same on my stationary computer (An Acer Aspire M3641 running Windows Vista 32 bit), I can't get past the UNetBootin splash screen.
Whichever option I choose, say for example "Try Ubuntu without installing" only brings up a flashing underscore at the bottom of the screen. (the options are still visible) This is what I remember happening from my laptop too (briefly before starting ubuntu), but here it never gets past this point, it just keeps flashing.
I suspect that the USB in some way disconnects from the computer as the light a few seconds after doing this turns off.
I did find somewhere a solution for problems with nVidia cards which suggested adding a parameter "nomodeset". I could not find the menu mentioned, but I did once by mistake stumble upon a single line containing the key words "silent splash", (the same ">something...." as what [tab] brings up, but with different text) so I tried adding nomodeset and pressed enter.
This actually seemed to start booting Ubuntu, although with a more simple look than usual. It displayed a screen with 4? dots and then from what it seemed, started loading system resources, listing them on the screen. I don't know the exact phrasing, but it stopped, displaying a massage along the lines of "medium not found". (Medium for loading system resources perhaps, I don't remember.)
I tried to burn a Live CD on my laptop, but it failed when it was almost done. I'm not sure why it failed, if it was too big (it says that it's 698 MB, so it should work) or another reason, but I don't feel like wasting CD's, so I've waited with trying that again. (I did by the way md5sum the iso)
Also as a final note, I did also make sure beforehand that the Acer supported 64 bit. If there is anything else you need to know, just tell me.
Thanks in advance for any help. :)
I'm apparently not able to comment because I didn't have an account when I wrote the question, so I'll have to comment with an answer instead. (I have an account now tough)
The computer is a few years old, so most likely USB 3.0 didn't exists when it was made.
I should have mentioned it in the original question, but I've already tried with three different USB sticks. Two (32 & 64 bit) via UNetBootin's automatic download, and one (64 bit) through downloading an iso file. Some people seemed to be having troubles with SanDisk U3 sticks, so I also made sure that the third was of another brand.
I've now tried the alternate version on USB. It seems to freeze at the language select screen, again with the USB turning off the light. (This however seems to happen before the language screen has appeared) I will investigate some more...
I've now also tried the alternate version via CD. (I made sure to md5sum the disc btw)
Running it from a CD, the GUI is different than from the USB. The first thing that appears is a language select screen. After choosing language, there's a purple screen with 5 options, (now in my native language):
- Install Ubuntu
- Test disk for defects
- Memory test
- Boot from primary hard drive
- Recover broken system
Using the first option, (after ~20 sec of black screen) I get to a screen of the same style as the language screen from running the USB. However, this seems to be regional settings instead. Again, it freezes like with the USB.
I tried the second option. After a minute of black screen, I get a purple screen followed by a warning that says:
"Your installation disc could not be mounted. This probably means that the cd wasn't in the tray. In that case you can insert it and try again.
Try to mount cd again?", followed by Yes/No buttons. It's however already frozen, so it's not possible to do either of them.
I also tried the memory test just to see if it worked and it didn't freeze.
Via F6, I do have access to this list of options, which I haven't yet tried out.
I might also try with english if that makes any difference.
