[SOLVED] BIOS refuses to detect my flash drive

Solution
Known from past experience, some older computers really dislike booting from USB and if it's possible you could try burning a dvd and using the dvd drive to install windows.
I don't know what model it is exactly, but it's an Argentine brand (Bangho) and it's old as hell (2012). It's got a 2nd gen i3, 4gb of RAM and a 500gb HDD, if that helps.

Edit: figured it out. It's a bangho b251xhu
