I can't boot from USB even though the BIOS is set to boot from USB first. Windows Boot manager somehow seems to be taking precedence. I have Windows 7, Linux Mint and Ubuntu installed on my hard-drive. When I boot-up those are the only options, despite having a USB stick plugged in then going into the BIOS and setting the UEFI USB stick as the primary boot device.
The USB device is fine as I can see it in Windows/Linux and can read the files. I made it bootable (in theory) by using linuxlive and/or pendrive with no success (though I've had success with both in the past).
Any suggestions?
1Did you try another USB port ? Did you try the stick in another machine? – Ofiris – 2013-05-31T12:41:43.323
Don't have another machine. I have tried all three ports. The drive stick worked before, but that was before I had installed Linux on the hdd and had to use windows boot manager. – Newb1 – 2013-05-31T13:04:46.790
I would try and remove the HDD from the
Boot
devices. If there is a problem with theUSB
device, it would tell you no OS was found. It sounds like currently, it tries to boot fromUSB
and skips to HDD. – Ofiris – 2013-05-31T13:11:14.373What's on the USB stick? Which BIOS do you have? I assume you're using Grub 2 for multi-booting at present? – Karan – 2013-06-01T06:35:19.380
Maybe your motherboard just don't support USB boot, it's totally possible, I have a few old PC that just don't boot on USB sticks... – Stakhanov – 2013-11-20T14:27:19.853
