I made an USB drive with ubuntu-12.04.2-desktop-amd64.iso.

I start the instalation and after some minutes the PC stops and the USB drive is no more read.

The USB Drive is correctly made since i tried it on an another PC and works very well, in both mode (run without instal, and with instal).

I do not have any protection in the HDD or BIOS.

The PC is an DELL LATITUDE E6430

What is the problem?

@karel Here, the installation disk boots and the installation will start, then it fails. So this is not the same problem as that. –  Eliah Kagan Jul 6 '13 at 19:45

I will do my best. I am fairly new to Ubuntu myself. It took me some reading of: http://www.linuxidentity.com/us/shop/index.php?act=viewProd&productId=58 Great magazine! I used it to install Ubuntu 12.04 "side by side" on my Lenovo laptop. Since I don't have a CD slot on my laptop I had to create a bootable USB stick.

What windows version are you running? I have W7. If you are looking to install your Ubuntu side by side with windows you will have to partition your hard drive. You could let Ubuntu do it or you can do it right on Windows. I partitioned my hard drive with the help of: http://youtu.be/q6_wwuBp0iI

After starting the Ubuntu installation it will ask you if you want to install side by side or "obliterate" windows. Always backup before any of the above tweaks. I hope that was helpful.

The version is Windows 7 32bit, and I usualy use Ubuntu to create the new partition. I already instaled Ubuntu desktop with the same USB drive on an another PC. But with this particular PC DELL LATITUDE 6430, the instalation freeze after 30-45 secondes. There is no error indication so I can not have more information about the problem. –  Nelson LOJA Jun 20 '13 at 8:13
How does this answer the question? This is too general on how to install. The OP has a specific issue with a freezing system during the installation/live system. –  gertvdijk Jul 6 '13 at 14:52
