External hard drive prevents boot up

  belayer 19:46 28 Sep 2007

I have just bought a Maxtor 3500 external hard drive, 500Gb. I use Windows XP.

With the Hard drive connected and power on the PC won't boot up, it just says 'NTLDR missing'. If I connect the hard drive after boot up its fine.

It ought to be possible to keep it connected all the time.

Any ideas?

Have you tried looking at the HDD management through My Computer because I'm sure I had a problem similar and i sorted it through there ...

Just an idea, might work

Also try Turning off 'USB Legacy Support' in the BIOS.

It worked for me.

Check the boot sequesnce in the bios and ensure that its not set to boot from an external device first.

Check your bios!

On most modern PC systems the bios will allow a boot from usb devices. Simply remove anything that you do not wish to boot from. eg floppy disk/cd/scsi/any other device. As a bonus it will also inprove your boot speed.

I have a western digital external 250gb drive, and it used to do the same.

Thanks for all the advice but, how do I check/change the BIOS?

It sounds a bit complicated.

Ussually hold F2 on the boot up screen. This will enter the BIOS setup.

If you haven`t done this before then be careful because you can mess up your machine while altering things. If it goes wrong just "load default settings" and restart the machine.
This will set everything to original specs.

Well, I tried all that, the only booting devices I can see are the Internal HD and CD in that order, nothing else. I have turned the USB legacy 'OFF', but its still the same.

Jameth182, where do I find what you are referring to?

I went to the Compaq website and downloaded the latest BIOS update - it works!!!!

It was an update intended to solve a boot problem with a particular model of USB printer connected, but it worked anyway.

Thanks everybody!
