So partitionning correctly another disk, dd source to dest to copy all partitions and install grub again fixed the issue. I am now able to boot on my lfs disk.
Quick note, although the support on the mailing list is great, it wouldn't hurt to tell people who makes a separate /boot partition to have another partition of 1M for grub. I installed arch before (uefi) and i actually had no idea. The book itself is a very good detailled tutorial with lots of explanation but imo if you cannot boot your lfs there is no point. Have a great day folks and thanks for all the support o/ ps : I use basic gmail for my mail, i know it is terrible and induce lots of top posting (had to set things to be able to quote) but i wasn't aware it did quotes terribly. If you have any advise for a good mailer i will gladly take it. 2016-06-29 11:16 GMT+02:00 thibaut noah <[email protected]>: > > > 2016-06-29 9:39 GMT+02:00 akhiezer <[email protected]>: > > For example, if: >> -- >> * you have two separate physical disks; >> >> * and your debian (without any ~unusual remappings/&c) sees them as sda >> (for disk1) & sdb (for disk2); >> >> * and you don't change the physical connections of the disks to the >> computer; >> >> * then your lfs should see the same sda (for disk1) & sdb (for disk2) >> - again, without any ~unusual remappings/&c. >> -- >> > They are both virtual disks and i am trying to run sdb alone (by creating > another virtual machine with just sdb as a virtual disk). > >> >> Paste the three pastebin contents into your message - not least as >> they'll be short-enough. >> > > Thought they were too long, my bad. > > Please note that my fstab and my grub file have been made with the > assumption that by having one disk only sdb would become sda on the new > virtual machine. > > fstab : > > > 1. /dev/sda1 / ext4 defaults 1 1 > 2. /dev/sda2 swap swap pri=1 0 0 > 3. /dev/sda3 /boot ext2 defaults 1 1 > 4. proc /proc proc nosuid,noexec,nodev 0 0 > 5. sysfs /sys sysfs nosuid,noexec,nodev 0 0 > 6. devpts /dev/pts devpts gid=5,mode=620 0 0 > 7. tmpfs /run tmpfs defaults 0 0 > 8. devtmpfs /dev devtmpfs mode=0755,nosuid 0 0 > > > >> >> > grub.cfg : > > > 1. # Begin /boot/grub/grub.cfg > 2. set default=0 > 3. set timeout=5 > 4. > 5. insmod ext2 > 6. set root=(hd0,3) > 7. > 8. menuentry "GNU/Linux, Linux 4.4.2-noah" { > 9. linux /vmlinuz-4.4.2-tnoah root=/dev/sda1 ro > 10. } > > > fdisk -l : > > - Disk /dev/sda: 8 GiB, 8589934592 bytes, 16777216 sectors > - Units: sectors of 1 * 512 = 512 bytes > - Sector size (logical/physical): 512 bytes / 512 bytes > - I/O size (minimum/optimal): 512 bytes / 512 bytes > - Disklabel type: dos > - Disk identifier: 0x5c2e89f5 > - > - Device Boot Start End Sectors Size Id Type > - /dev/sda1 * 2048 15988735 15986688 7.6G 83 Linux > - /dev/sda2 15990782 16775167 784386 383M 5 Extended > - /dev/sda5 15990784 16775167 784384 383M 82 Linux swap / Solaris > - > - Disk /dev/sdb: 15 GiB, 16106127360 bytes, 31457280 sectors > - Units: sectors of 1 * 512 = 512 bytes > - Sector size (logical/physical): 512 bytes / 512 bytes > - I/O size (minimum/optimal): 512 bytes / 512 bytes > - Disklabel type: gpt > - Disk identifier: F700B567-368F-4096-BB5B-6B2A5C670F10 > - > - Device Start End Sectors Size Type > - /dev/sdb1 2048 20973567 20971520 10G Linux filesystem > - /dev/sdb2 20973568 29362175 8388608 4G Linux filesystem > - /dev/sdb3 29362176 31457246 2095071 1023M BIOS boot > > >> >> >> >> -- >> -- >> 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. >> >> A: Because it messes up the order in which people normally read text. >> Q: Why is top-posting such a bad thing? >> A: Top-posting. >> Q: What is the most annoying thing in e-mail? >> >> http://en.wikipedia.org/wiki/Posting_style >> > >
