I recently attempted to install Ubuntu 12.04 onto Satellite and problems during the boot splash, right after grub. I tried booting from a USB as well as a CD. I put a friend's hard drive into the Satellite and Ubuntu loaded up just fine. I also attempted to install Ubuntu onto my hard drive from my friend's computer and Ubuntu worked fine from the hard drive when it was on his computer. As soon as I put the hard drive back into the Satellite, I faced the issue in which my computer would get stuck at the boot splash.
Computer: Toshiba Satellite L855 - S5242 Processor: AMD A8-4500M APU Video Card: AMD Radeon HD 7640G 6Gb RAM
I think it might have something to do with the network card because during the boot splash, the starting up of the network manager would stop the boot and it would get stuck.
