SituationI have Arch Linux installed on /dev/sda1 (15GB/ext4). / and /boot are both on /dev/sda1 and /home is on /dev/sda2 (100GB/ext4). I made a 15GB/ext4 /dev/sda3 partition for Ubuntu. I installed Syslinux as the bootloader.ProblemHow do I dual-boot-install Ubuntu onto /dev/sda3 without installing GRUB, without ruining my Syslinx bootloader and how do I share the home partition /dev/sda2 between the two OS's?UpdateI learned how to boot into Ubuntu correctly and found out that chainloading is unnecessary.Here's what I did:Wiped Ubuntu off /dev/sda3 and reinstalled it in the same place.Made a new directory on /dev/sda1 named /boot/ubuntu,Copied all of /boot from /dev/sda3 to the new directory in step 1 (because the the kernel and initrd files for Ubuntu were there),Edited /boot/syslinux/syslinux.cfg from /dev/sda1. See below for the entry:LABEL Ubuntu     MENU LABEL Ubuntu     LINUX ../ubuntu/vmlinuz-3.5.0-23-generic     APPEND root=/dev/sda3 ro     INITRD ../ubuntu/initrd.img-3.5.0-23-genericIf I were smart, I would probably have a dedicated boot partition. Oh well, it wasn't part of the original question so I'll just worry about that later.However, I was hoping that Ubuntu would use /dev/sda2 as the shared home partition and it didn't :(Anybody know how to fix the /home/user folder so it's on /dev/sda2?
Add Ubuntu to Arch linux Dual boot, Keeping Syslinux, without GRUB
ubuntu;arch linux;partition;dual boot;syslinux
