Talk:Grub2 Bootloader

GRUB changes

GRUB_DEFAULT=0
GRUB_HIDDEN_TIMEOUT=0
GRUB_HIDDEN_TIMEOUT_QUIET=true
GRUB_TIMEOUT=10
GRUB_DISTRIBUTOR=`lsb_release -i -s 2> /dev/null || echo Debian`
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"
GRUB_CMDLINE_LINUX=""

• You can change the default from 0 to any number, corresponding to the entry in the Grub bootup menu (first entry is 0, second is 1, etc.)
• You can change the "hidden timeout" (no menu); and also display the countdown (GRUB_HIDDEN_TIMEOUT_QUIET=false)
• You can force the grub menu to show by commenting out the two GRUB_HIDDEN lines with a # at the beginning of the line

How to boot in compatibility mode after install

sudo vi /etc/default/grub

Save & exit.

Change line GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to:

GRUB_CMDLINE_LINUX_DEFAULT="noapic noacpi nosplash irqpoll"

Update grub:

sudo update-grub

Graphic problems....

GRUB_CMDLINE_LINUX_DEFAULT="nomodeset nosplash irqpoll"

This solves when Mint shows login screen but when you login you see only cursor and nothing else.
