Hi, I would like to share a difficulty I have with my Computer. I have windows 7 Ultimate 32-bit and I would like to put Ubuntu 16.04.2. I burnt the.iso file into my USB using unetbootin-windows-625.exe. It extracted all the files into the USB and then I restarted my Computer (I made sure to have plenty of space to install on my pc). After that, I pressed F12 and went into the booting menu. I tried every single one of the options and nothing worked. If you could help me I would be very happy.
