this is absolutly normal, you chroot the device you need to arch-chroot the device. a Big difference exist betweem them. chroot is made for remove change file not for working with it. for working on the system you need to mount filesystem on the mounting point (e.g. /mnt) like :
mount -o nosuid,noexec,nodev -t proc proc "$newroot"/proc
mount -o nosuid,noexec,nodev -t sysfs sys "$newroot"/sys
mount -o mode=0755,nosuid -t devtmpfs dev "$newroot"/dev
mount -o mode=0620,gid=5,nosuid,noexec -t devpts devpts "$newroot"/dev/pts
mount -o mode=1777,nosuid,nodev -t tmpfs shm "$newroot"/dev/shm
mount -o nosuid,nodev,mode=0755 -t tmpfs run "$newroot"/run
mount -o mode=1777,strictatime,nodev,nosuid -t tmpfs tmp "$newroot"/tmp
replacing newroot by your mountpoint
This is made automaticly by the script arch-chroot :) when you tape this :
$ sudo arch-chroot /mnt
i guess debian don't use arch-root (is a part of archlinux), so boot on obarun-iso usbstick, then mount your partition on /mnt (or media, it's up to you) then arch-chroot the mnt
$ sudo mount /dev/sdb3 /mnt
$ sudo arch-chroot /mnt
now you can change what do you want on the /mnt mounting point (e.g installing spécial stuff, rewrite your fstab, want do you want) for example
$ blkid
Well you use a dualboot that it's mean you use bootloader from debian (grub or syslinux i don't now) but be sure that your append line is correctly define like :
APPEND root=/dev/sdb3
or using uuid
APPEND root=UUID=1234 (replacing 1234 by the correct uuid)
if you prefer using /dev/sdb3 in your fstab , just rewrite manualy your /etc/fstab entry or erase your /etc/fstab then (i'm talking about the fstab that you have in your sdb3 partition where obarun is installed)
genfstab -p /mnt >> /mnt/etc/fstab
to make this command line you need to have mounted the partition on /mnt but you don't need to arch-chroot the /mnt mounting point
hope this help :)
