[lfs-support] Another Question on Dual Boot
I have built an LFS system that I now wish to migrate to my main box. To do this, I plugged in a USB drive, mounted it to /root/tmp , and ran the command: dd if=/dev/sda1 bs=64K | gzip -c > tmp/drive.gz On my main box, I will fire up a live cd, plug in my USB drive and restore with this command gunzip -c tmp/drive.gz | dd of=/dev/sda2 bs=64K The reason it won't be sda1 is because windows is on there. After doing that, I will chroot into the newly restored system and run grub-install /dev/sda And of course, I'll update /etc/fstab /etc/hosts /etc/hostname and so on to conform to the new system. My question is on the grub.cfg syntax so that I can boot windows. I guessed it will probably look something like this: menuentry "Windows 7" { insmod chain insmod ntfs set root=(hd0,msdos1) chainloader +1 } Will that work, or will I need something more complex? -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

Just mount the formatted /dev/sda2 as e.g. /media. cp -a /root/tmp/* /media The reason it won't be sda1 is because windows is on there.

Depending on your build, you may need to rebuild the kernel with the appropriate drivers. My question is on the grub.cfg syntax so that I can boot windows. I guessed it will probably look something like this: menuentry "Windows 7" { insmod chain insmod ntfs set root=(hd0,msdos1) chainloader +1 } I don't do Windows, so I can't help there. What you have seems reasonable. -- bruce -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.

Looking at my backups from the box which ran win7 (the mobo died, but the config seemed to work until that time), I had # revised invocation based on gentoo menuentry 'Windows 7 (loader) (on /dev/sda1)' { insmod part_msdos insmod ntfs insmod chain chainloader (hd0,1)+1 } Mine used DOS partitions, hence the use of part_msdos : I guess that part could have been in the general parms. I suspect that what you have suggested will do the same thing as what I cribbed from gentoo. ĸen -- `I shall take my mountains', said Lu-Tze. `The climate will be good for them.' -- Small Gods -- http://lists.linuxfromscratch.org/listinfo/lfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page Do not top post on this list.
