I made some Live USBs using both Tuxboot and USB Image Writer but I can't boot any of them. I've tried most of them on other computers and they all work.
When I press ESC while booting I'm taken to the grub menu, but only my main system appears there (Linux Mint 18.1) and an option to go to the BIOS config.
If I go to the BIOS and change the boot order so that EFI Flash goes first the system reboots but boots normally on my main OS. The next time I access the BIOS the order is returned to the original settings.
A few notes:
- I have a samsung NP900 laptop with SSD
- I'm using the linux kernel v4.10 on a Mint 18.1
- I have secure boot set as custom, and I haven't tried without it because I'm worried by system won't boot
The output of
BootCurrent: 0006 Timeout: 0 seconds BootOrder: 0006,0005,0004,0002,0000 Boot0000* Windows Boot Manager Boot0002* Windows Boot Manager Boot0004* UEFI: Generic Flash Disk 5.00 Boot0005* UEFI: Generic Flash Disk 5.00 Boot0006* ubuntu
Those two Windows entries are there, but I don't have any Windows installed. I changed the boot order with
sudo efibootmgr -o 0004,0005,0006,0000,0002 and rebooted but again, system booted into main OS. And after I checked boot order again it was set as
0006,0005,0004,0002,0000, which is not what it was when I restarted it.
