One of my students had an HP laptop that stopped working. The librarian thought it would be a good idea to replace the current os with Lubuntu. After trying many times the installation wasn't working. I took to the internet and was able to boot the live version with the USB. Even then, I wasn't able to access GParted or most other applications. Eventually I found out that if I tried booting in using acpi=off I was able to get in and use everything. Rebootting the laptop causes a boot error unless I have the USB in and even then I can only use the system if I click the "try lubuntu without installing" option. Now I am trying to run Boot-Repair but it doesn't seem to be working. I am very new to the system and I don't think I'm all that tech savvy so I'm asking your help. The pastebin url boot-repair gave me was http://paste.ubuntu.com/26083623/
Please send help!
P.S. I only need Lubuntu, I don't plan on duel-booting with windows or anything.
