Hello. I have some questions regarding my motherboard and bios. I haven't upgraded it since i bought it and right now its version is F10. Since i have a 2500k and i want to oc it , many guides and videos were made using UEFI bios . First of all, is there any danger when flashing UEFI and/or just updating bios version(lets say to F13)? And secondly, i 've read over the net that some say that 'll need a bootable usb, and some others that i can do it via windows and a gui version. Can you please tell me if thats possible at all? Thx in advance and sorry for any bad grammar mistakes ^^
