I had 2 PATA drives and disconnected my slave and installed a SATA
drive. I mirrored my HD with XXCLONE and checked the option to make
the new drive bootable. My system booted from the PATA drive so I
disconnected it and re-booted, but then got a message "no OS
installed".
I have the PATA drive still on the primary IDE controller and do
not
know if I need to change the jumper to "slave". My Windows
directory
IS on the SATA drive.
Go into your BIOS and change the boot drive order to include the SATA
controller.
I did not see a SATA controller in the BIOS
If the boot drive sequence option in BIOS doesn't list a SATA controlled
device then you cannot boot from it. The best you can do at this point
is to get a SATA-to-IDE adapter (it slides onto the back of the SATA
drive or is an interface card that hangs with the cables) to connect the
SATA drive to an IDE port.
After the BIOS completes the POST, it searches for the first physically
detectable hard drive and reads the first sector off of it (the MBR, or
master boot record). The first 446 bytes of that sector is the
bootstrap program which reads the partition table from that same sector
to determine which is the "active" marked primary partition. That
bootstrap program in the MBR then loads the first sector of the
active-marked partition and passes control to it. That is the
partition's boot sector and used to start the loading of the OS
contained within that partition (or the loader for that OS). The BIOS
bootstrap program loads the MBR bootstrap program that loads the
partition's boot sector. That is for the standard bootstrap program in
the MBR (but alternates can be installed there, like for multi-boot
managers, disk overlays to handle large drives when the BIOS can't
handle them, security products that encrypt the entire hard drive,
etc.).
In the BIOS should be a setting for the order of boot devices. Normally
it would be floppy drive (A:), CD-ROM drive, and then hard drive (IDE).
If there is no bootable diskette in the floppy drive and no bootable
disc in the CD/DVD drive then the first hard drive found attached to an
IDE port gets used (in the order of master and then slave starting from
IDE0 and then to IDE1). If the BIOS has support for the SATA ports then
it should also list the SATA controller in the boot drive order. You
will need to hit PageUp or PageDown (or whatever your BIOS uses) to
switch between the different preset configurations of boot drive
ordering until you see the SATA item included.
If your BIOS doesn't support booting from the SATA drive, just how are
you going to connect your SATA drive to the motherboard? If there are
SATA controllers on the motherboard then the BIOS needs to support them
(it may actually be a separate BIOS but should be accessible by the
system BIOS). You never mentioned WHICH motherboard that you have. I
suppose it could treat the SATA drive as a SCSI-like device and present
the SATA BIOS at a later time which would mean the POST completes, you
see the ESCD screen listing the hardware setup (by the BIOS), and then
would see a message showing the SATA BIOS got loaded and you can hit a
key within a few seconds to open the screens to that BIOS. Hard to know
when no details were provided as to which motherboard you are using.
If your motherboard doesn't support SATA devices (and why SATA is
missing from the boot drive ordering option) then maybe you are using a
SATA controller PCI daughercard. Since its BIOS runs *after* the system
BIOS, you must ensure that the system BIOS can't find a hard drive from
which it will try to boot. The SATA card may provide the ability to
boot from a SATA drive but not if the system BIOS has already started
the boot sequence from a hard drive on an IDE port. That means you need
to disconnect all hard drives from the IDE port so the system BIOS
doesn't find a hard drive to boot from. Then later the SATA BIOS, when
it loads, can boot from a SATA drive. If you still need to use the IDE
drives, you could get an IDE controller PCI daughtercard to use for the
old IDE drives. The system BIOS will see no hard drives connected to
the IDE ports so it can't boot from a hard drive, the IDE card would
need to be configured to NOT boot from any of its drives, so the SATA
card is the only one left whose BIOS can boot from drives attached to
it.
As yet, no one knows WHICH brand and model of motherboard that you have
to provide specific solutions.
So you think it would help if I told you which mobo I have? It is a
Dell in the Poweredge 400SC. When I asked Dell who makes the mobo they
said they make their own.
The SATA ports are right on the mobo...I will poke around the bios some
more.
Thanks!!
Eddie
