Why won’t my desktop boot up on bootable Ubuntu USB thumb drive? I changed BIOS to boot USB first. Lenovo with AMD Ath. X2 32 bit win10; ATI Radion 3000. I think it reads it but it doesn’t boot on USB drive. It beeps then loads into Windows 10. I’m wanting to install dual boot. I have the: xubuntu-16.04-desktop-i386.iso Used Rufus-3.4.exe to create USB bootable
USB checks out ok. How do I test .iso file is corrupt ?
