I'm running Laptop with single OS: UbuntuMATE 15.04 Beta1 64bit on Toshiba laptop Core i3. After burning "Elementary OS" on a live USB drive using UNetbootin, what happened is:

-After reboot, laptop directly shows UbuntuMATE boot screen, doesn't show Toshiba logo at the begginning as usual. So no access to BIOS or boot menu anymore. So it boots directly to UbuntuMATE and it runs normally.

  • Installed Boot-Repair and ran (Recommended Repair); it gets aborted showing me this message: "Please use this software in a live-session (live-CD or live-USB). This will enable this feature"... which I can't boot from a live CD or USB as I lost access to boot menu.

  • Boot info summary gave me this link http://paste.ubuntu.com/10664795/ which I can ask for help providing information in it.

  • I looked around into several posts but couldn't find what matches my case.

What exactly am I supposed to do? I'm a little new to Linux (3 months) and I'm still learning, so I do not know much.

  • Try pressing repeatedly the same keys you used to use for BIOS settings and boot menu just the same, immediately after pressing the power button. You must have disabled the Boot splash screen somehow. – To Do Oct 2 '15 at 7:44

It sounds like you enabled the "fast boot" option in your BIOS setup which disables the F2 setup and F12 boot menu prompts.

Power-off your laptop and hold down the F2 key, then power it on for the BIOS setup utility. Disable "fast boot", save and reboot.

  • still can't access BIOS with holding f2. – aeid Sep 24 '18 at 9:23

First, try to run update-grub (as root)

If that does not work - try:

gksudo gedit /etc/default/grub

should show something like:


You can change GRUB_TIMEOUT=10 to however long you want grub to show up. Then, save the file and run update-grub again

  • His problem is with accessing BIOS and boot menu, not with Grub. – To Do Oct 2 '15 at 7:42

Updating grub timeout to 10 and then rebooting while hitting the delete key did the trick for me.
