Thread: Dualboot-install, but no boot-loader!

i installed ubuntu next windows 7 in new laptop. choosing automatic partitioning grub didn't installet. came window saying couldn't installed , critical error.
reinstalled , time choose manually set partitions. didn't delete partitions, created new ones , resized old.

first created partition boot, 1 root, 1 home , 1 swap. installation went without hassle, when restarted computer bootloader didn't came up. windows started automatically.

did wrong?

partitioning looks this:
/dev/sda
/dev/sda1 fat16 41mb
/dev/sda2 ntfs 788mb
/dev/sda3 ntfs 90000mb
/dev/sda5 ext4 /boot 500mb
/dev/sda7 ext4 / 39998mb
/dev/sda8 ext4 /home 168733mb
/dev/sda6 swap 19999mb

you can try fast way add live mode, need longer way... lets see.

short way live mode , using partition scheme gave us, is:

code:

sudo mount /dev/sda7 /mnt  sudo mount /dev/sda5 /mnt/boot  sudo grub-install --root-directory=/mnt /dev/sda

reboot , see if worked. note overwrite windows bootloader on mbr , if grub2 files missing might not work until longer procedure.
