Thanks for reply it's window pin, I'm going to give this a go tonight.PIN at which section? CMOS / BIOS or after login to Windows?
if in CMOS / BIOS you may bring it over to computer shop for the CMOS / BIOS to be reset ofr look in Google according to the model of the laptop on self-reset,remember this trick will require you to dismantle certain section of the laptop panels for reset.
if in Windows, just download original ISO from Microsoft website and burn using RUFUS (refer here https://www.windows11forums.com/threads/windows-11-education-to-windows-11-home.1673/post-6576)
final choice is to contact the seller / previous owner for the recovery disc.
Hope this helps, and please post if you have any queries
