Posted 08 February 2013 - 23:31

I have an SSD and a normal HDD in my system

SSD was in the laptop and HDD was in a caddy in the optical bay

when SSD was in everything worked fine

when i then add the HDD in the optical bay i get a boot loop when trying to load grub like the laptop is trying to boot from the optical bay first, this is disabled in bios

If i switch the SSD into the optical bay and HDD into laptop it all works fine

Below is my grub2.cfg

I have tried chaning all the hd0 to hd1 but this makes no difference

here is my grub2.cfg

I might be being a complete idiots here

if i switch the drives around does SDA become SDB and vice versa?

Edit: that should not make any difference really should it?

First - why do you have all the repetition?

Second - Why is msdos in your grub?

Hi Haggis,

Sorry for the short replies I was stuck replying on my Andriod phone.

Exactly, why do you have all the initramfs's from different versions? You would only run into compatibility issues trying to boot from an older img. It is not urgent by any means just - extra data stored for no reason.

It is odd that both are set for root level. -- Why? I have always built my own and I am not sure what the advantage would be in your scenario.

I am using standard partition not LVM so is that maybe why?
