re organise grub menu [SOLVED]

[mtvexl]

I have a partition on one of my Pc's that has both Linux and win 7 and comes up with the grub menu at the beginning where you choose which to use. Normally it will boot into Linux if you don't do anything. I've been using a game lately that I can only play on Win 7 and I would like to rearrange the grub menu to boot into Win 7 first. I say this because it is an old Pc and takes ages to settle down. I am using the same monitor for 2 Pc's which I can switch from one to the other so whilst I'm on my main pc the other can be booting up merrily in the background.
I imagine it's something to do with partition protocol but am not expert enough to go there so need a little help
regards Michael

Look at:

Code: Select all

cat /etc/default/grub

It looks like this:

Code: Select all

 ➜ cat /etc/default/grub
# 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=0
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"

# Uncomment to disable graphical terminal (grub-pc only)
#GRUB_TERMINAL=console

# The resolution used on graphical terminal
# note that you can use only modes which your graphic card supports via VBE
# you can see them in real GRUB with the command `vbeinfo'
#GRUB_GFXMODE=640x480

# Uncomment if you don't want GRUB to pass "root=UUID=xxx" parameter to Linux
#GRUB_DISABLE_LINUX_UUID=true

# Uncomment to disable generation of recovery mode menu entries
#GRUB_DISABLE_RECOVERY="true"

# Uncomment to get a beep at grub start
#GRUB_INIT_TUNE="480 440 1"

The entry GRUB_DEFAULT=0 determines which entry in the list is the default booted entry. So you can change that to other numbers like 1, 2 etc. to make it boot into Windows.

The list is "zero-indexed" so the first entry is 0, the second is 1, and so on. When you are booting, you can count which entry in your boot list is Windows, then subtract 1 from that.

You can edit the file with

Code: Select all

xed admin:///etc/default/grub

Save changes and close the file. Then run

Code: Select all

sudo update-grub

Thanks for your reply.
Erm Can't find even where to begin. I've tried the command line and the terminal thing but can't find
Code: Select all

Go to Menu and type "Terminal"

[jimallyn]

but can't find
Code: Select all

You don't want or need to find Code: Select all. "Code: Select all" just indicates that code follows in the box below, and you can select that text by clicking SELECT ALL so that you can paste it into a terminal or somewhere else. It is NOT part of the command.

Hi Thanks for your reply.
I opened terminal and typed in 'cat/etc/default/grub' and got 'No such file or directory'

cat /etc/default/grub There is a space after cat. Learn and practise basics of Linux commands. One such link is https://www.guru99.com/must-know-linux-commands.html

Ok. I perservered and found that I needed to add two spaces after 'cat' and managed to enter the 'xed admin' etc and have succeeded in changing it.
So Thankyou very much for your help. 5 stars all round

You are welcome but you will do well to learn some basic Linux commands.
