I tried installing Ubuntu 12.04.3 from a flash drive to dual-boot with my current Win7 Operating System; after putting the .iso on it with Linux Pen Drive It booted on the flash very well, but when it got to the part of the installation where you choose how you want to install it, I picked "Install alongside Windows 7".
After I clicked "Continue", it restarted my computer, there was a few command lines that came up, then the installer restarted from the beginning. I tried to install over 20 times, but to no avail. Please help! I really like both Ubuntu & Win7, and would really appreciate some help.
