Many common problems are answered in the FAQ document, so if you experience problems please check whether http://crux.nu/Main/Faq contains answers to your questions already.
If you have further questions, there's a dedicated mailing list for CRUX, and an IRC channel. Actual information about these can be found on the Community page of our wiki.
Installing a new boot manager is like modifying the partition table using fdisk or installing a new system kernel. Please create a rescue boot disk first!
CRUX comes with a heavily patched version of grub. Use it at your own risk!
After installation you need to copy the stage files to /boot/grub/:
# cp /usr/share/grub/i386-pc/* /boot/grub/
(Of course, you can choose another location as described above but this guide assumes that you use /boot/grub. Normally you need only the files stage1 and stage2. Please read the grub documentation if you don't know why: http://www.uruk.org/orig-grub/ and http://www.gnu.org/software/grub/manual/grub.html)
Now it's time to create your own "boot menu":
# # Copy sample file # cp /boot/grub/grub.conf.sample /boot/grub/grub.conf # # Modify it for your system # vi /boot/grub/grub.conf
For more information about setting up your own grub boot menu file: http://www.gnu.org/software/grub/manual/grub.html#Configuration
Last but not least, install/enable the boot manager:
# # Run grub # grub grub> root (hdX,Y) grub> setup (hdX) grub> quit
Please correct the path and device names according to your configuration. Also see http://www.gnu.org/software/grub/manual/grub.html#Installation. In the example above,
Y need to be replaced with your hard drive and grub partition.
