So i decided installing linux mint in on my pc it's a really old pc the Bios mode is Legacy, i created a bootable usb stick using rufus but usb does not shows up in bios. I had same issue while installing windows 10 using windows media creation tool on my pc then i had to download iso and flash it using rufus and selecting the partition scheme to mbr as my bios is legacy ,i did the same for installing linux however it does not shows up in bios. What can i do??
