I was about to post a question, when I saw this discussion. There might be other reasons beyond dual-boot - incompatibility with legacy boot devices. I've recently got Lenovo Thinkbook 13s-IML laptop and I'm unable to boot LFS 9.1 on it at all. I planned to replace W10 with BLFS build, but decided to try USB stick first. It boots fine on ThinkPad T450s, but Thinkbook 13s. This laptop has NVMe as a boot disk with W10, secure boot=off, boot mode legacy first. Each time I end up in Boot manager GUI with USB stick as an option, but after a few seconds it returns to the same screen. Grub stage 1 never shown. There only one thing I didn't try is EFI boot option in LFS due to fragmented info and time required to make it right. Since majority of new laptops have EFI, it would really help to have EFI section as a default option in the book. Another suggestion I have regarding initrd: since grub config is created in LFS book, it would be nice to move initramfs from BLFS ch.5 to ch8 LFS. It would make changing of boot procedure complete in LFS instead of BLFS. Due to dependency cpio has to be built in LFS as well (and possible lz4 for future compatibility). I could try EFI variant on Thinkbook 13s laptop if you decide to include EFI in the new book (or dev. version of the book) Regards, Alexey -- http://lists.linuxfromscratch.org/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
