Q: B Tree nodee-My hardrive crashed, but I have a new external drive. How to install boot OS w/o App Store

My hard drive crashed on my Macbook Pro A1278. Disk Utility and internet reinstall both failed. Installer log says the apple server connection is missing.

Utiltiy disk gives Invalid B tree node error. I want to save as many files from the internal hard drive, but for right now. Getting an OS installer is my biggest issue. Any help? I have a 1TB external drive already formatted and journaled. I cant get to the app store  nor itunes because as sson as i boot my sytem, I am taken the the select language page...then the four optin for time machine back up, disk utility, re install and get help online. I'm using that browser now. but its not upgrade so i cant check certain links with the apple site. I really need help please. I tried a PRAM and FSCK rest from terminal. Mid level tech savvy. Any and all replies are welcome

    Do you have a backup? If not, try using Disk Utility/Restore to copy the internal drive to the external. Please note that this will reformat the destination partition and any data on the external will be erased. Once that is done, boot to the Recovery Volume (command - R on a restart or hold down the option/alt key during a restart and select Recovery Volume). Run Disk Utility Verify/Repair and Repair Permissions until you get no errors. Then re-install the OS.

    If that doesn't work, try booting using the command - option/alt - R keys to boot into Internet Recovery (if you computer is new enough to use it).
