Struggling to install via USB

[skar]

I was trying to install linux lite on my acer aspire v5 laptop. its a pretty beefy laptop and a recent one. I've been using windows 8.1 and ubuntu on it side by side. Now I want to install just linux lite. I tried the windows utily, win32diskimager. That does not work. It just corrupts the usb or the usb wont show up on the boot menu. The linux commands did not work on ubuntu either. I tried unetbootin and universalusbinstaller, where i got some success by booting in, but the installer would fail at grub install stage. Kind of expected as I was using ubuntu boot images...

I really want to install the OS as my main OS, as I was impressed by its performance on virtualbox.

Any help is much appreciated.
