I don't know much about Linux / Windows booting nor am I am computer geek, however I did try installing Ubuntu (Alongside Windows as it appeared while installing) 16.04 and was successful with dual boot options.
But unfortunately post Ubuntu installation, I am unable to boot Windows 10. No error is being displayed either. I only get the same grub menu with Ubuntu boot options every time I select Windows 10. I have already pasted the boot repair data generated at
/dev/sda6
not being defined properly. Also from a performance standpoint all your partitions do not start on a physical sector boundary which will slow things down a bit. However I have no experience fixing these problems. – WinEunuuchs2Unix Feb 4 '18 at 15:58
