UNIX for Dummies Questions & Answers

Hello all,

I'm trying to recover from backup file to a new system with a new disk. I'm able to partition my new hard drive the same way as my old drive, but I'm unable to boot off of it. I have set the fdisk to toogle as a boot flag. But it does not seem to be working. Does anyone know how to install a boot sector with fdisk?

Thanks

What hardware, OS, backup type? Without this information your question is oo vague to be answerable.

I have a Dell powerEdge with SCSI Disks RAID drive.
Running Redhat AS3 update 4.

What method of backup are you using?

Also, what happens when you try to boot (you say it wont boot but what's the error you see?).

Cheers,

Sorry about not making it clear but here is the detail..

I have a Dell poweredge 2650 and it has 5 SCSI drive. The orginal I have drive 0 and 1 mirror and dive 2 and 3 mirror and drive 4 is just a straight SCSI. I have a dump level 0 of dive 0 and drive 2, which I would like to recover completely. The new drive I have are a little smaller and the RAID I have configured is different. Drive 0 is a plain volume while drive 1 and 2 are strips and drive 4 is the backup drive I'm restoring the drives from. I have manually partition the drives with fdisk to reflect the orginal partition table of the system. During fdisk I have also toggle the boot flag and made a boot partition on drive 0 which is where the orginal was kept.
Then I manually restore the dump level 0 from dive 4. Which restore OK. Then I change the /etc/fstab to reflect my new partition table and removed all mount point that may have been in the mtab. I have made the /boot and / partition as close to the orginal as possible. Now when I exit from rescue mode. I system will not boot (It does not even load drivers). It looks like a machine with no OS. It seems to not see the boot partition or the boot image. I have checked the permission and everything, but I'm lost as to why it won't boot.
