Hi everyone, thought this bit of information might help

Having not used my macbook pro 2012 for a couple of years, I tried to boot and had the familiar folder briefcase symbol with the Q mark

Read all I could on the situation and attempted various procedures until I came across a thread written by DeltaMac (cat symbol) from 2017 April 25 in macrumours

quote from DeltaMac " Reset your NVRAM:
Restart. Before the boot chime ends, hold Option-Command-P-R.
Continue to hold those keys. You should hear the boot chime again in a few seconds.
Continue to hold the same 4 keys until you hear the boot chime 2 more times, then release the keys.
Assuming there is no system installed on your new SSD, you SHOULD see a flashing folder and (?).

Now you can boot to your installer " unquote

I followed this interesting advice as it was my last option having dried for a good few days
Anyhow, without switching off and rebooting from the flashing folder, I inserted a boot usb preloaded with Yosemite 10:10 .2 and lo and behold the software booted in immediately and began loading the program ....
30 minutes or so later it was all done 🙂

My thanks to DeltaMac for this invaluable advice, and hope others have similar good luck
FYI, I purchased boot programme from Amazon which was brilliant
