So I've messed up my install completely via ignorance. I'd had windows 8 Pro and ubuntu 14, which I installed using unetbootin and a USB, running on partitions on my hard drive, then realised I don't use ubuntu 14 anymore. I deleted the partition it was on, and re-formatted it as an exFAT partition. Now, whenever I turn on my computer, a command line interface appears saying:
error: unknown filesystem Entering rescue mode... grub rescue>
I have attempted to use a windows install disk, and a windows install USB, however both of these attempts failed and I was sent straight back to the command line screen. A common suggestion I saw on the internet was to do:
And find the windows install from there. However, I have tried this on all 5 of the displayed partitions, and they all come up with the same error:
error: unknown filesystem.
How on earth do I fix this?
