I really wish I knew Elizabeth.
The BIOS re-write happened when attempted to remove Linux and reinstall Windows. I understand from a computer tech at my local university, that the Linux OS may have altered a setting but this wasn't put back because I didn't use the right routine to uninstall it. Though to be fair, that was a guess.
The re-writing of my Windows drive happened when I attempted to use the Linux dual BOOT routine. I was advised I must have done done something wrong there as well. (Though the same Tech suggested I would have been better using the Windows dual BOOT routine, or better still, sticking with Windows.)
Getting any information or support is almost impossible. I did join a few Linux forums but was either ignored or had my posts moved here and there, because 'They Had Been Posted in the Wrong place'.
Every Linux user begins by asking you which version you use then says, 'You'd be better using this, or that.'
The how to guides seem to waffle on getting no-where. Have a look at these for example, all on the same topic:

I'm sure Linux is a wonderful OS. It doesn't load many sites. Doesn't use loads of software or online social activities. There is no support, it's never heard of intuitive or user friendly. It tries so hard to look just like Windows.
If I were every to try it again, I'd do so on another machine and preferably in a different house, using a different ISP and a pair of rubber gloves!
