I have installed a dual boot of ubuntu 18.10 and windows 10.

Now when I startup my PC it goes directly to windows 10, I have to click esc to abort the automatic startup and go to the GRUB options.

I want my PC to startup in GRUB so I can choose from the momento I turn on y PC.

I have tested this process:

1. Boot into Ubuntu.



2. Hold CTRL-ALT-T to open a terminal




3. Run:sudo update-grub2 and allow GRUB to update it's list of operating systems.



4. Close Terminal.


5. Restart Computer.

But it dind't worked. The terminal says that if it didn't workes I should post this URL in a Forum:

http://paste.ubuntu.com/p/VKW6QVyZWD/

Could somebody help me?

First 15 lines of the Grub File:

# If you change this file, run 'update-grub' afterwards to update

# /boot/grub/grub.cfg.

# For full documentation of the options in this file, see:

#   info -f grub -n 'Simple configuration'



GRUB_DEFAULT=0

#GRUB_TIMEOUT_STYLE=hidden

GRUB_TIMEOUT=10

#GRUB_HIDDEN_TIMEOUT=10

GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

GRUB_CMDLINE_LINUX=""



# Uncomment to enable BadRAM filtering, modify to suit your needs

# This works with Linux (no patch required) and with any kernel that obtains

# the memory map information from GRUB (GNU Mach, kernel of FreeBSD ...)

#GRUB_BADRAM="0x01234567,0xfefefefe,0x89abcdef,0xefefefef"

When I run the following command, grep -A3 -B1 timeout /boot/grub/grub.cfg I get:

/boot/grub/grub.cfg-if [ "${recordfail}" = 1 ] ; then

/boot/grub/grub.cfg:  set timeout=30

/boot/grub/grub.cfg-else

/boot/grub/grub.cfg:  if [ x$feature_timeout_style = xy ] ; then

/boot/grub/grub.cfg:    set timeout_style=menu

/boot/grub/grub.cfg:    set timeout=10

/boot/grub/grub.cfg:  # Fallback normal timeout code in case the timeout_style feature is

/boot/grub/grub.cfg-  # unavailable.

/boot/grub/grub.cfg-  else

/boot/grub/grub.cfg:    set timeout=10

If you want GRUB menu to be shown at startup, then comment out

GRUB_TIMEOUT_STYLE=hidden

to be

#GRUB_TIMEOUT_STYLE=hidden

to /etc/default/grub, then run

sudo update-grub
