That is for my point drivers issue, not grub issue if you didn't touch some settings. If you get to recovery mode, that is good. Connect your PC to internet and install gpu drivers.

How to find info about your GPU:

lspci | grep VGA

or

sudo lshw -C video | grep product:

or

lspci -nn |egrep "VGA|Display"

;)

sorry for my late reply.

finally got something to work.

here's how i kinda solved the issue:
1. enter grub recovery mode, and choose root shell
2. remount the filesystem so that can read and write using command "mount -o remount,rw /"
3. edit the grub config using "sudo nano /etc/default/grub"
4. modify the line GRUB_CMDLINE_LINUX_DEFAULT="quite splash" to GRUB_CMDLINE_LINUX_DEFAULT="quite nomodeset"
5. uncomment the GRUB_GFXMODE line
6. save and write the changes using command Ctrl o + Ctrl x
7. rebuild the grub config using command "sudo update-grub"
8. reboot my laptop using command "sudo reboot"

after that, i can login to backbox on tty1, and then type command startx to start the graphical mode.

anyway, thanks Zerof for the help!
