MDT 2010 offline USB MEDIA - Bootmgr missing after disconnect usb and reboot
-
Thursday, March 17, 2011 6:05 PM
A custom image was captured using imagex. This image was used in the Tasksequence in MDT part of the Hydration kit. A usb key was prepped to use as offline media.
Install went smoothly. Reboot after install also went correctly.
Problem: after disconnecting usb and reboot Laptop mentions bootmgr is missing. Trying to boot from usb also didn't work anymore. Only option was to boot from CD and use diskpart to delete everything.
Any ideas ? I think that the drives got different letters after reboot but don't know how to prevent this.

Hi,
According to your description, this error was caused by PC cannot find the boot partition. I suggest to perform these tests you can try:
1 Unplug all unnecessary hardware, USB driver. Sometimes the issues caused by external Hard disk connecting with the PC
2 Perform a Startup Repair in WinRE
There is a link to fix “Bootmngr is missing. Press Ctrl+Alt+Delete to restart”. It works on Windows Vista but still works on Windows 7

If you're receiving the message "BOOTMGR is missing, Press Ctrl+Alt+Del to restart" message? Don't stress! Its easier to fix than you think. Here's how:
SOLUTION 1 :
- Get your Vista installation DVD and pop it into your drive.
- Then restart your computer.
- Set your computer to boot from DVD or CD in your BIOS.
Vista will ask you for language and keyboard layout information, after which you will be asked if you want to re-install Vista or repair your existing installation.
Select Repair. After which Vista's System Recovery Tool will start.For more info on bootmgr is missing
