grub2 - How do I customize the GRUB 2 menu? - Ask Ubuntu

this grub 2 menu looks far:

i want few things here:

• i want rename "windows boot manager (on /dev/sda1)" "windows 8.1".
• i'd rename "ubuntu" "lubuntu 14.04.1".
• i'd switch order of options this:
  • windows 8.1
  • lubuntu 14.04.1
  • advanced options lubuntu

(windows default os)

if helps in way, i'll explain steps took prior this, since new linux , don't know information required.

1. i bought laptop on amazon (asus x551mav-eb01-b) pre-installed windows 8.1 64-bit
2. i downloaded proper lubuntu .iso file system (lubuntu 14.04.1 amd64) , put on flash drive (via unetbootin)
3. i went disk management, , shrunk c:/ drive down 32gb 32gb free lubuntu
4. i used flash drive (32gb sandisk cruzer) liveusb lubuntu 14.04.1
5. i went through install process. didn't recognize windows 8.1 had "something else" option.
6. i highlighted free space, , pressed + button
7. i created 10,000mb ext4 partition , mount point / (is dev/sda7)
8. i created 4,000mb swap area partition (is dev/sda8)
9. i created ext4 partition using rest of free space , mount point /home (is dev/sda9)
10. i selected dev/sda7 install lubuntu , selected dev/sda7 bootloader installation
11. it installed fine, booted fine, , i'm happy know grub 2 menu works.
12. now i'm here asking question

how customize grub menu:

download/install grub-customizer latest version.

or install via terminal:

this ppa contains latest release of grub customizer.

sudo add-apt-repository ppa:danielrichter2007/grub-customizer sudo apt-get update sudo apt-get install grub-customizer 

among grub customizer features are:

• edit menu entries (reorder, rename, add or remove entries)
• edit contents of menu entries or create new ones (internally edits 40_custom)
• change default boot entry
• change menu visibility , timeout
• disable recovery entries
• change grub resolution, menu colors or background image
• grub repair & configuration using live cd
• advanced options booting iso, changing kernel parameters , lots more

---

after installation launch 'grub customizer' dash , see in screenshot see window(i unexpanded "advanced options ubuntu")

then lets start answer how questions.

how rename entries:

if want rename menu entries, under "list configuration" tab, first select entry , right-click on , select "rename" context menu. type new name , hit enter.

now renamed both "ubuntu > lubuntu 14.04.1" , "windows boot manager (on /dev/sda1) "windows 8.1".

how change order of entries:

to reordering menu entries, above, first select entry , right-click on , select "move up/move down" context menu move entry up/down. (also can use up/down arrow tool-bar )

now after renaming , reordering entries have list.

now last question: how make entry default:

after changing order of menu entries, first entry default entry. in case windows 8.1 default os if moved , it's first entry of list. or can use "general settings" tab , select "windows 8.1" default entry list box. see screenshot:

that's it. after finished changes press "save" (the icon under main menu) save changes.
