First of all, I am completely new to Ubuntu and not very knowledgeable with computers in general. Please forgive me for my explanation maybe being vague or word choice being incorrect.
I am using a Windows 8 and wanted to try Ubuntu by installing from a USB. I used Unetbootin to install the files on an USB. After following the wizard and installing Ubuntu through the USB, I was told to reboot the system. After that, I encountered two problems.
1) The Ubuntu install never seemed to have been successful. Even after the full install process, I only have the "try ubuntu" or "install ubuntu" options on the grub menu.
2) The bigger problem. I am unable to access Windows anymore, even if I change the booting order to my original HDD through the F2 option.
I have looked for solutions on the internet and have tried using Boot-Repair
I was able to navigate through Boot-Repair's instructions smoothly, however, the last message said "There was an error during the repair . . . you may now reboot your system," and neither of my problems have been solved. The log of the repair is as follows: It would be great if you could take a look at it since it's my only way to concretely explain my situation.

I also read about using a windows repair-cd or usb, but my laptop has no cd drive and I am unable to acquire usbs to fix my windows system as of now.
Will I need to reformat my windows system?
I would b very grateful to receive some help on this.
Thanks,
