If you have Win 10 installed, try accessing the BIOS area through Windows.

Here’s a link that shows how to do this.

Thanks - but I need to be able to access BIOS ( e.g. pressing F2 at start-up) in case

it doesn't recognise new SSD .



Fair enough but perhaps if the old HDD with OS was still installed in there you could alter the BIOS settings before you insert the new SSD so that you can then access it at startup.

You may also want to edit your question to mention about the SSD in case someone else gives similar answer to mine without reading your comment here. Saves on repeats


Sorry - hadn't realised there had been a follow-up answer. Thanks that would work - but I think I found a different solution - on windows 8.1 - windows key - then type "power button" - select " Change settings that are currently unavailable" - turn off fast start-up then bios available via F2. Thanks for taking time out to answer my question.


Oh yes. Fast Startup! That one has tripped me a few times.
