So, I've had a Gigabyte GA-78LMT-USB3 motherboard for about 10 months, I bought it used on eBay, and today I decided to change the SSD for some data that I didn't want to delete, but at the same time I needed to reinstall Windows due to driver problems. I then prepared the Windows 10 Installer USB, and at the end of the installation, I noticed that there are no other partitions except the Windows one. I tried changing SSD and USB, but nothing seems to happen. finally, now it doesn't even boot bootable USBs anymore. the most it can do is enter the bios and boot menu. does anyone know how to help me?
