| + | You can also install multiple different kernels. | ||
| + | |||
| + | By default kernel installation also generates initrd based on mounted /proc, /sys, /dev files and configured fstab, modprobe.conf and few others configuration files. generated initrd (which by default is initramfs cpio image) is saved in /boot. | ||
| + | |||
| + | If something fails or you want to regenerate initrd manually you can do it using: | ||
| + | |||
| + | <file>/sbin/geninitrd -v -f /boot/initd-XXX-Y.gz XXX-Y</file> | ||
| + | |||
| + | command. Real example: | ||
| + | |||
| + | <file>/sbin/geninitrd -v -f /boot/initd-4.20.3-1.gz 4.20.3-1</file> | ||
| + | |||
| + | //-v// option causes geninitrd to write additional information, so you can see if proper kernel modules are being installed into initrd. | ||
| + | If booting with new initrd fails you can use **debuginitrd** and **debuginitrd=sh** boot kernel cmdline options to debug the problem. | ||
| ===== Bootloader ===== | ===== Bootloader ===== | ||
| + | ==== grub2 ==== | ||
| - | ==== lilo ==== | + | Install grub2 on boot sector of disk: |
| + | |||
| + | <file>grub-install /dev/sda</file> | ||
| + | |||
| + | Generate configuration file for grub2: | ||
| + | |||
| + | <file>update-grub</file> | ||
| + | |||
| + | Resulting file is saved as **/boot/grub/grub.cfg**. | ||
| + | |||

| - | A Grub's shell will started. Let's make some changes: | ||
| - | |||
| - | <file>grub> root (hd0,1) | ||
| - | grub> setup (hd0) | ||
| - | grub> quit | ||
