Aspire V3-772g Ubuntu install problem

I recently bought an Aspire V3-772g and I now want to install Ubuntu as second OS. I already replaced Win8 with Win7, and reconfigured the HDD to MBR instead of GPT to do so, and also disabled Secure Boot and switched to Legacy Boot.

I got the Ubuntu 12.04 image from the official site and created a Live-USB-Stick via Unetbootin. I installed Ubuntu alongside Win7 on my desktop machine already using this stick, and had no problems with it.

I can boot my netbook with that stick and get into the menu, where I can choose between installing Ubuntu, trying without installing, etc, but then the problems start. As soon as I press any key on the keyboard, the notebook freezes. The LED on the USB stick stops blinking and stays on continuously instead. When I let the countdown at the bottom count to zero, to make it use the default selection, a blinking cursor ('_') appears below, but other than that nothing happens (appart from the USB LED also stying on). In both cases I have to shutdown the notebook manually to use it again.

Has anyone an idea what the problem might be, or a suggestion/manual to install Ubuntu on the notebook using any alternative way?

(I already consider switching back to UEFI/GPT, but before I resort to such drastic methods I wanted to try and find something less nerve-wracking)

Apparently the problem really was the unetbootin bootloader. I was able to install using the Rufus Life-Stick. Still had a small problem with a black screen (solved by 'nomodeset') and gparted/Ubuntu-Install not seeing my existing partitions (due to Windows not being able to convert to MBR correctly...corrected via this), but now it seems to be running smoothly.

Good for you on upgrading to Win7! 8^) If you've got your Win7 installation running smoothly, I recommend a virtual Ubuntu installation using VMWare's VMPlayer freeware. I'm currently running a SuSE version, WinXP & Win98SE as VMPlayer virtuals on my Win7 host, each communicating with the others thru the network.

Win7 runs perfectly. I really don't want a virtual machine, since I want Linux to have full access to the entire File System, in case Windows prevents me from doing something it deems stupid, like preventing me to delete a file that 'isn't mine'. Also since Ubuntu boots way faster than Windows, I intend to boot into Linux for the most day-to-day work and only launch Win7, if I want to play a game or do some work wth win-only programs, like Photoshop or 3ds Max.

But I think I found the issue: the Laptop seems to not like the Unetbootin boot-loader. I created a Live-Stick using Rufus last night (at 4AM) and was able to boot into the Live Ubuntu. Will try later today, if it installs properly and then runs without problems.
