Hi @manurehappens ,
Do you know anyone with a Win 10 computer?
If so you can create a Recovery USB from their computer.
Go to Control panel > Recovery.
It takes about 40 minutes and needs a 4GB (8GB to be safe) USB flashdrive.
You say that you can get into BIOS, so when you have the recovery USB change boot order in your laptop to USB 1st (you may also have to enable Legacy boot or CSM - however it is listed in BIOS to get it to boot.
Once in Recovery, select Troubleshooting > Advanced.
DO NOT select reset my pc as this will reinstall Win 10 and erase all your data. Use repair startup option.
