Fix or Reinstall Questions

[CortonaJ]

I have an Acer aspire, until recently it worked fine with 12.4 on dual boot. I switched to windows as the place I was staying had wifi that refused to work with Ubuntu. After this when I tried to boot I got grub rescue. I partially solved the problem by running boot repair but I have lost ubuntu, and now boot straight into windows. Everything on the disk is backed up through drop box. My question is can I just install a more recent version of Ubuntu now or will that leave me with a partition full of files I can't access?

Moved to your own thread.
Post link to Boot-Repair's Summary report.
And see caution at top of link in my signature if you have Windows 8. Reinstall has a major bug that may erase system. Only use Something Else.

Is system UEFI or BIOS, Summary report will tell us and then we can make better suggestions.
