Mindovermaster Moderator Posted August 7, 2016 Moderator Share Posted August 7, 2016 Change your boot order in BIOS to the USB drive as first device. If that doesn't work, then you didn't install uNetbbotin correctly. This happened several times to me, just remake the USB flash drive. Link to comment Share on other sites More sharing options...

When installing a dual-boot system, Windows is usually installed first. This is because Linux does a much better job with GRUB in setting up the bootloader. If you do it the other way, you have to manually reset Windows in the bootloader, which is not hard, but another step that isn't necessary if you install Windows first. http://www.howtogeek.com/214571/how-to-dual-boot-linux-on-your-pc/ Link to comment Share on other sites More sharing options...
Haggis Veteran Posted August 8, 2016 Veteran Share Posted August 8, 2016 use unetbootin to put it on a usb or hell burn it to a CD/DVD should work fine from there Link to comment Share on other sites More sharing options...
Radium Posted August 14, 2016 Share Posted August 14, 2016 It's easier to handle multi boot in UEFI since bootloaders can coexist. Each operating system install their bootloader and saves an entry in the UEFI's NVRAM which will show up as a boot entry when you press the boot menu key. The Linux kernel can be booted directly as well so a bootloader is not mandatory. If you install distributions from Canonical or Redhat then you can keep secure boot on since their keys are trusted on modern machines. You can also sign UEFI-binaries yourself if your distribution doesn't come with a signed bootloader. Sometimes, Windows will change the boot order on UEFI systems and some firmware allows you to make the boot order list write protected. Linux works fine in UEFI. I have signed the GRUB UEFI binary with my own key and it allows me to have full system encryption (kernel & initramfs included) and secure boot on my laptop. Only a 5 MB signed binary is unencrypted. If Windows was installed and booted with UEFI then turning off UEFI actually just enabled a compatibility systems modules that makes UEFI emulate a BIOS and Windows won't boot. Remember, UEFI motherboards emulate BIOS, they don't have dual firmware. I recommend that you use UEFI which allows you to use GPT which supports much larges drives and it has two copies of the partition table. If you want to keep Windows then use UEFI if Windows was installed in UEFI mode. This will avoid having to switch between UEFI and CSM which only makes the boot process slower and adds unnecessary complexity. Link to comment Share on other sites More sharing options...
