cant get ubuntu to work on my hp pavilion a450n

[CosmicChan]

hello ubuntu community, i have been trying my hardest to get ubuntu to work on my hp pavillion a450n tower. when i use the wubi installer i get the error no cd in drive meassage, and when i use a flash drive (well technacly its a microsd card in a reader) it gets to the purple ubuntu splash screen and then just stays there. for the usb ive tried it on multiple computers and the same thing happens on all of them. i am looking to either get ubuntu to run alongside windows or if possible replace windows on my tower. thanks in advance

- i believe i forgot to mention im running xp on the tower atm

Hello Chan, and welcome to the forums!

Have you tried booting from a CD? Also, if multiple computers give the same result with the USB flash drive, then I doubt the integrity of the iso you downloaded. Accordingly, I suggest to follow this:

Please post your systems' specs, especially, the amount of RAM. At least 1 GB RAM is recommended for Ubuntu 11.04 with Unity. If you have less than this amount of RAM, try Xubuntu (http://www.xubuntu.org/getubuntu) or Lubuntu (https://help.ubuntu.com/community/Lubuntu/GetLubuntu) instead (for newer kernel), or just stick with 10.04.

If you are really keen to use natty, try this:


First of all, please verify that your downloaded iso is not corrupt itself: https://help.ubuntu.com/community/HowToMD5SUM
After the integrity of the downloaded image is verified, do the following:
while booting, press any key. This should bring up advance boot menu.
In the advance menu, after selecting language, press F6. This will pop up "Other options" menu.
In this menu, select (by highlighting with arrow keys and pressing "spacebar"): acpi=off and nomodeset. Then press escape key, and selecting "Try without installing..", press 'Enter'.
If this does not help to boot normally, retry by also selecting noapic, nolapic and nodmraid this time.

For a detailed info on customized booting, follow this (thanks to drs305 for the link): https://help.ubuntu.com/community/LiveCDBootOptions.

As a side note, I suggest not to make any changes to your current installation (of xp) until the compatibility of your hardware with ubuntu is verified successfully. Or, you can make a backup image of the installation, then proceed as you wish. Just to be safe.
