Re: tried to boot but nothing changed
That can mean 4 things:
1. You didn't set the BIOS to boot from that USB-drive.
2. The portable drive has gone south, needs cleaning of the head or doesn't have enough power.
3. The Windows disk isn't bootable.
4. The motherboard has gone south. That most likely means a new laptop.
It's up to you (or the repair shop) to find out which of the 4.
