Why does my computer not boot with external hard drive?

by anorwood1 / January 9, 2015 4:31 AM PST

When my external hard drive is connected via USB to my computer upon booting up it will not boot unless I unplug the external hard drive. Once the computer is up I can re-connect the hard drive with no problem, it just won't me boot up while connected. Can anyone assist with information?

That's a BIOS issue.

- What computer?
- What motherboard?
- What BIOS?
- USB 2 or USB 3?
- USB on the back or on the front port?
- What does the makers helpdesk say about it?
- Did it ever work on this computer?
- New computer? Then you can make it a warranty issue or a reason to return it.

In reply to: That's a BIOS issue.

The computer is an HP, 64 bit
Not sure abiut motherboard
USB is in the back
This is a pre-owned computer so no helpdesk available
I believe it worked at one time.

You just wrote the magic words. A few years ago my LAST HP (literally) would not boot when my smart phone was plugged in. It would also have mysterious hangs when storage devices were plugged in. THIS DID NOT HAPPEN ON THE DOZEN PLUS OTHER MACHINES IN THE OFFICE.

To make this simple for HP I took it down to one issue. The laptop would not boot when the iPhone was plugged in.

HP failed so badly that it was my last HP and I no longer recommend their products due to them taking a walk on the warranty.

The bug is in the BIOS which HP said "We buy the BIOS" and more. Since HP doesn't have control over that, they could never fix it. Now that's bad enough but at just weeks into owning this model it went to their service center and came back. After their service it would lock up solid (no phone or any changes to the system) in 5 minutes.

Calls to HP ended with "We've done all we could." At 9 months after over 6 months of calls and surveys, I called it quits. HP's non-commitment to warranty issues means they are not a company we can buy from.

Your choice to see if HP can resolve this for you but if I was to do over, I'd go for any other model.

Disconnect the HD before turn on the PC. connect it when your OS gets loaded. It wont solve the exact issue but yes it will provide painless path of connection.
Sometimes Priority booting from USB can lead to such situation. Change priority of booting use HD at first position.

It could be anything as follow:

Connecting HD before turning on PC can confuse device.
There could be a possibility that HD contains files in root directory that confuses the PC. Select hidden file from control panel and click on the button which shows hidden file.

i have the same issue with my external drive (my book essential) but it never done that till i got a new computer (lenovo) from an older gateway. called WD tech support, he said the computer is reading the drive so the more stuff on there the longer it will take. he suggested to eject or reject drive before re-booting. i asked if anyway around that, but he had no other solution. right now i'm compressing my external drive to see if that will help, only have 19 hours to go (very frustrated)
THERE HAS TO BE A WAY AROUND THIS maybe another type of back up system.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
