This contradicts the question in your Topic...
Turn off USB boot.
I agree. My original question was not stated clearly.

I should have said I have a USB hard drive that is not intended to be configured as a bootable device. When I plug it in and start the system for some unknown reason the message Boot table missing appears. When I plug-in a bootable USB flash drive the system boots from the flash drive. When I start the system without a bootable USB device the system boots from the internal hard drive.

The problem is when I plug in the USB hard drive for some reason it looks Boot Mgr. and message appears Boot Mgr Missing. It is not suppose to be configured as a bootable device. If I start the system, then plug it in, I can read/write files to the drive.

Attached is a file that shows the directory on the US hard drive. What are the files .disk and boot.sdi? Do they belong on a non bootable device?

Everything you describe is the expected behavior with your boot order configured the way it is.

The reason you are getting the message boot manager is missing is because it is not configured to be bootable.

Again, that is the expected behavior,

You need to change the boot order to the internal hard drive first and it won't try to boot when you have the external plugged in.

If you still want to be able to boot from other devices you can use the one time boot menu by pressing F12 when the Dell logo appears and select from there.

Here's this link again if you need it.

If you plug in a bootable flash drive and start you computer then the bios is picking up your flash drive before it sees your drive C that Windows is installed on. Somewhere in your bios the C drive is not set to first boot. Their might be two places in your bios to set these things.

Press F2 when the Dell logo shows and locate the boot order options and set the internal hdd to first device. http://pcsupport.about.com/od/fixthe...rderchange.htm

Dead is a humanism. Since a computer does not have a soul, its use here is inappropriate. I was referring to the fact Windows will not start.

You are going in circles KCav.
Non bootable flash drive will not boot. It shouldn't.
Bootable flash drive boots. It should if set that way in bios.
When no flash drive is installed Windows 7 boots of of the C drive. It should.

Flash drives of any kind will not boot before C drive with Windows 7 unless something or some one has the boot order set to boot USB before C drive with Windows 7 installed. Period.
Your bios are not set to boot the drive Windows 7 is installed on first. Period.

Your post #16 is absolutely useless. It tells us nothing.
Fix your bios to boot in proper order.

[/QUOTE] The reason you are getting the message boot manager is missing is because it is not configured to be bootable. [/QUOTE]



I thought if a USB device was configured to be non-bootable that the BIOS would pass-m by. Here's what happened when I tried what I thought would work.
  1. Formatted a USB flash drive to make sure it was not configured to be bootable.
  2. Plugged it into my PC with BIOS boot sequence set to boot from USB first
  3. Screen said "Boot Manager missing."
[/QUOTE] You need to change the boot order to the internal hard drive first and it won't try to boot when you have the external plugged in. [/QUOTE]



OK, I'll try it. Here's what happened.
  1. Pressed F12 while system was starting
  2. From Startup Options, selected BIOS, then Boot Sequence
  3. Made Internal hard drive first in sequence` and shut down the system
  4. Plugged-in USB FD and stated system
  5. System booted from internal hard drive
[/QUOTE] If you still want to be able to boot from other devices you can use the one time boot menu by pressing F12 when the Dell logo appears and select from there. [/QUOTE]



I want to be able to boot from USB Rescue device. Here's what I did.
  1. Ran YUMI - Your Universal Multisystem Installer
  2. Answered YUMI Installation Wizard questions: 1) Selected USB FD 2) Scrolled down long list of ISO's to Custom Installation 3) Browsed to where I stored ISO files created with Macrium Reflect 4) Pressed Create YUMI. It worked
  3. With BIOS set to boot from internal hard drive, and YUMI flash drive plugged-in I started the system, and while the system was starting I pressed F12 key
  4. A menu for Start-up options appeared, selected USB and the system proceeded to boot from USB to YUMI's Menu
  5. Plugged in the USB hard drive where I stored image files made with Macrium Reflect and inserted new internal hard drive.
  6. Went to the YUMI menu and selected the ISO made with Macrium Reflect
  7. YUMI loaded the Macrium Reflect Backup and Restore program and detected both the USB HD and internal HD
  8. Browsed to select the file I wanted to restore and selected the internal hard drive as the destination.
  9. Pressed restore and within 15 minutes the process was complete.
Layback Bear, Thank you.
