Won't Boot! How do I make a OS X back-up BOOTABLE?

Both drives are Firewire.

I just backed-up my OS X drive to a larger, newer drive that I will be
using from now on.

Now it won't boot.

All the files are there, but no go.

How do I make my new copy of my OS X drive boot up?

I heard there may be bootability problems when you back up a drive - so
how do I fix this?

Thanks!

Please do not post identical posts in many groups without cross-posting,
and if you do that, keep the number of groups to a minimum. Separate
postings make it impossible to follow the thread.

For an answer, see my reply in c.s.m.s.

Use Carbon Copy Cloner - or if you want command line, see the website on
how to do it.

Works like a charm

Or if you value your ACLs and other extended attributes, use SuperDuper.

Do you use ACLs on your Mac?

I do on mine. Specifically to support a family iPhoto album which any
family member (i.e. member of the family group) can add, edit, or delete
photos.

I know I certainly don't - so that's never bothered me. Standard Unix
permissions suffice for all my needs. Then again, I'm not running huge,
multi-user file servers or anything of that nature, where you need
finer-grained control of permissions.

Not personally, but ISTR SuperDuper is one of the only utils that will
backup and restore them properly, so just something to be aware of. (On
the command line, rsync also does so these days, if you're backing up to
another HFS+ filesystem and pass it the -E option.)

So ACLs are not a reason why you chose SuperDuper, but rather a post-hoc
rationalization.

IMO, advising someone to choose a Mac backup system based on its handling
of ACLs is rather pointless, since they are not used by more than a
minuscule percentage of Mac users. Looking at www.macosxhints.com, I
see that Tom's use for sharing iPhoto libraries is the only actual hint
there that uses ACLs.

"If you value your ACLs" is a phrase that implies that ACLs are somehow
important and _should_ be valued, when in fact they are non-existent on
99.99%+ (PFA estimate) of all OSX Macs in service today.

While SuperDuper is no doubt a fine tool for backups using syncing, I
don't believe that disparaging other products for a failure to address
ACLs is useful.

Couldn't have said that better myself. :)

Not really... the knowledge that SuperDuper would preserve ACLs should I
choose to use them, as I do on some of my other Unix and Linux boxes,
was very much a factor in my decision to purchase. Even if I never use
them, it's comforting to know that the people who wrote my backup
software understand my filesystem to that level of detail.

True, but for all I know, the OP might be part of that miniscule
percentage, so there's no harm in letting them know.

I for one appreciated your comment, as having used ACLs on more than one
other OS for over 20 years, it's useful to know that not all backup
solutions cater for them.

First, some firewire drives are bootable, some are not! If you Google
that issue, you will find info, as well, at apple.com discussions,
macfixit.com, etc.
If you search this forum, the issue has been addressed many times.

I use SuperDuper app, which even works with Intel Macs (some apps do
not).

Without knowing your Mac model, and particulars of your set-up, it is
hard to give advice.
