two harddrive

[jtravnick]

So I'm thinking of throwing in a second harddrive into my system so I can install F8 on it and leave my running install of F7 intact. My question here is should I unplug the hard drive that has F7 on it so I dont mess with it or is there a way of doing the install of F8 with both hard drives pluged in? Also what do I do about grub if I do unplug the first hard drive? I dont need grub on the second hard drive do I?

Thanks
Jim

I think just making sure you have the right drive selected, and deselecting the other one during the install process should be fine. You'll see the option when you come upon selecting the layout.

ok so I now have two hard drive on my system with F7 on the first and F8 on the second. So that part went well the thing is where I think I messed up is where I told it to boot F8 I told it to boot off the first hard drive. Figured thats where I already had grub. Well grub works fine boots to F8 no problem.

Heres the problem though I can no longer get to my F7. Do I just need to edit grub to put F7 back in? If so what do I put?

The whole reson I did this was so I could take my time moving everything over to F8 and this way once I was done could use that hard drive for F9 when that comes out.

Oh and by the way so far F8 works great for me like what I'm seeing so far

yes, you'll have to edit grub, since fedora has a history of not always finding other installs(however due to different HDD's, i think that's why it didn't detect.).
I think you'll probably be able to copy what's already in there for F8, except changing kernel versions and "f8" to "f7". If you mess up somewhere, just come back under F8 and post the grub for someone to help debug.

Here is what I have in grub:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

Ok got it all fixed now. Ican now boot both F7 and F8. What I had to do was edit my grub menu to include F7 lucky I hadnt done anything to the wifes system so just went to her system and copyed what was in her grub menu for F7 so mine now looks like this:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

# kernel /vmlinuz-version ro root=/dev/VolGroup01/LogVol00
# initrd /initrd-version.img
#boot=/dev/sda

Hope this helps anyone else that runs into this problem. As I said before I have F7 and F8 on two seperate hard drives and when I installed F8 I had it put grub on my first hard drive where F7 already was. I not expecting any problems as I dont think I will be updating F7 anymore just moving things over to F8. Not sure what an update to the kernel in F7 would do to my grub now so will just leave well enough alone.
