I think when grub fails in the stage 1.5 that indicates it can't find the /boot partition therefore it can't find the grub.conf file. It knows how to load the raided partitions so something weird is happening. To troubleshoot temporarily create the /boot partition on the ide drive and put the grub.conf. The way you know this is it can't put up the menu, if it puts up the menu then it has found the grub.conf file, but can't find the kernel. > -----Original Message----- > From: redhat-list-admin@xxxxxxxxxx [mailto:redhat-list-admin@xxxxxxxxxx] > On Behalf Of Pete Nesbitt > Sent: Saturday, February 07, 2004 9:36 PM > To: redhat-list@xxxxxxxxxx > Subject: Re: Trouble with GRUB and multiple HD's > > On February 7, 2004 06:37 pm, Harry Hoffman wrote: > > Hi Pete, > > > > The drive HAS to be bootable "as it is right now".
