I am sorry you have to reinstall Windows, but you have over two bootable disk errors, which signify severe corruption on the partition itself, not Microsoft Windows. In the event this happens, it is best to just delete or format the partition that Windows sits on, then create a new simple volume to let a fresh install of Windows to lie on.

Ok no worries, I am extremely grateful for all of your time and help.

Does this mean that I will lose all of the data on my laptop? I have lots of files on my laptop that are extremely important.

Any further help would again be extremely appreciated.

On OTLPE, you might be able to transfer files to a flash drive, then you might save the data.

I still have some testing to do on OTLPPE to be sure of that.
