Setup /boot on sdb correctly from a workstation to multiboot
by JockVSJock from LinuxQuestions.org on (#592E3)
I have two ssd drives in a RHEL workstation, sda and sdb.
My end goal is to install another version of RHEL to sdb from a home grown iso, modify grub and upon bootup, be able to select either too boot from, either sda or sdb.
I am not sure if there is an installer, like Anaconda, that I can run manually to do the install. Googling around, doesn't appear that is possible.
I've setup swap partition and / under sdb using parted, however I need to setup /boot, but since there is already a /boot partition under sda and currently can't.
I did try to create a tmp directory under /tmp, called /tmp/boot, which pointed to /dev/sdb1, copy the contents from the iso /boot directory under there and create an entry under /etc/fstab, used an UUID, but these seemed to cause issue with /boot under sda and I ended breaking the workstation that I was trying to do this on.
Hopefully what I'm explaining makes sense.
thanks
