VHD booting question


I'm currently using this to make my LFS 7.2 system:

50GB VHD /dev/sdb mounted to /mnt/lfs

If I use GRUB2 as a bootloader is there anything special I have to do inside of LFS to avoid GRUB2 detecting Slackware so I can detach the VHD drive and either boot from it from another virtual machine or from Windows 7's BCD as it's own device?

You can compile LFS anywhere. I've built an LFS by mounting a flash drive on /mnt/lfs.

When you install grub you should just be able to execute grub-install /dev/sdb (instead of /dev/sda) and then write your config file and such. This will put the boot files in /boot/grub so make sure you've set up your partitions the way you want (i.e. if you want a separate /boot partition that you've set it up and mounted it) and that you run this from within the chroot environment so that the proper /boot will be used.

When you write your config file, write it as if your VHD is /dev/sda, since that's what the device will be called when you boot the VHD somewhere else. (i.e. if your root partition is, say, /dev/sdb2 right now, then use /dev/sda2 in your config file.)

Cool, thanks man. I have the system booted up in VirtualBox which I used to build it using the Slackware64 Huge Kernel, and I'm going to write in a BCD entry for it tomorrow for a full hardware level test. Afterwards it will go back into VirtualBox for the second phase of adding BLFS packages for a complete system.
