I have a new Acer Aspire S7. I tried to install Ubuntu, alongside with Windows 8, but i messed up in the middle, and now i can't even run Windows 8. I'm desperated, when i turn the computer on, it asks me to enter a bootable device. I made a backup with the Acer tool, but it doesn't seem to work. I don't know what to do.
I leave you the report of what boot-repair returned: http://paste.ubuntu.com/8520860/
