Need help with instalation plz

[Xaulleon]

Hi guys, first of all Im a beginner, I downloaded the iso from http://www.ubuntu.com/desktop/get-ubuntu/download and burned it using infra recorder. I restarted my pc to instal ubuntu however a purple screen with commands shows up and I dont know what to do, plz help.
I have a HP pavilion dv4 with windows 7

What commands do you see?
Also, as a precaution, before you elect to install Ubuntu it would be wise (using a HP) to find out how many primary partitions are already in use on your hard drive. If you already have 4 primarys you will need to delete one before installing another OS.

An install that is going well will progress past the point you describe to a series of graphical screens that tell you what is going on, occasionally asking for input to ensure the installation is correct for your application. In fact, you should get the opportunity to choose whether you're doing an install or running a 'live' session from the CD/DVD. Since your install is stalling, I suggest your .iso may be bad.

You can verify whether your iso source file is correct. The directions should be on the page from which you downloaded it, but I haven't checked. Others have suggested that the iso should be burned to CD/DVD at the slowest speed possible to ensure that it is done correctly, but I haven't had that experience myself.

If any of the 'commands' you're seeing on the purple screen look like error messages, note what they are, copied and pasted if possible, and post those to help diagnose and correct the problem.

alright, I tried to install but I had the same problem, heres what shows up:
BusyBox v1.15.3 (Ubuntu 1:1.15.3-1ubuntu5) built-in shell (ash)
enter 'help; for a list of built-in commands

(initramfs)mount)mount: mounting/dev/loop0 on//filesystem.squashfs failed : input/output error

can not mount /dev/loop0 (/cdrom/casper/filesystem.squashfs) on //filesystem.squashfs


*I also tried using wubi, however it said something about permission denied...

When you first boot the Live CD you should see a purple screen with two small graphics at the bottom once the system/bios screen passes. When that screen appears you have 3 seconds to press a key (any key) to display the boot options.

If you get that screen to display then select "Check disc for defects". It takes a few minutes to run, if it passes without errors then select "Try Ubuntu without changes" and make sure the Live CD runs on your hardware.

Once you're sure the Live CD runs on your hardware you should check and see how many Primary partitions already exist. You can do so by running this command from terminal:


sudo parted -l

Mine is insane but just as an example:


lance@lance-desktop:~$ sudo parted -l
[sudo] password for lance:

You can see from that I have two drives and on the 500GB drive I have many partitions but only 3 are primary partitions, the rest are logical partitions created within an extended partition.

Should you find that you already have 4 primary partitions STOP! You'll need help!

You should also know that bugs exist in the new 10.10 live installer:
