Boot Sequence problem

Hi

My recently bought store assembled computer is configured like this



I also have a Western Digital 500Gb Ext HDD which isn't permanently connected. My problem is that when the Ext HDD is connected the boot sequence automatically places the WD HDD as first boot device and I get a "NTLDR missing" message.No boot up. If I disconnect it, before boot up - no problems. Tried setting and resetting the boot sequence devices in the bios - problem continues. I'd like to leave the HDD connected during boot up - or not - but that should not affect my boot sequence, right ?

Is the external USB, or ide in an enclosure? If Ide is it set to slave or cable detect?

Yes, he tried to change the boot order from what I read. This seems insanely unlikely to me, but did you change the boot order with the drive plugged in. I don't think it would matter, but you never know.

My WD Ext HDD is USB2 connected.

When I try setting boot sequence with the drive connected my bios displays the Ext HDD and my DVD drive as the only available drives ! When the Ext drive is disconnected my internal HDD is displayed. There, I think, is where the problem is.

In BIOS, on Boot screen:

Boot Device Priority: 1st Optical Drive, 2nd OS HDD, 3rd can be blank

Hard Disc Drives: 1st should be OS

Also, on a reach

Advanced tab: Legacy USB Support- Auto

To set OS HDD as my 2nd boot device it has to show / be listed - which it doesn't when the Ext HDD is connected. That's my problem

WD needs to be taken out of the first slot under HD's, which may be on a different tab than Boot Order.

Look under HD's everywhere they are listed in BIOS, and you will find the place where they register when plugged in.

Somehow WD is registering in the first slot when plugged in and bumps the OS HD to second, so it needs to be moved to second slot there before you even deal with Boot Order.

Then you can set OS HD to be first HD to boot.

Yes that seems to be the problem. I have looked in the BIOS but did not find (or recognize) where or how this could be done.

Is your HD plugged into SATA 1?

From your manual, look at this setting in BIOS:
