ReplyT.WMay 12, 2018 at 7:07 pmThanks for this. Spent hours with Hirens boot CD and various MBR editors trying to get a system to boot after a power spike reset the BIOS settings. While the data on the boot drive was intact, every effort resulted in ‘BOOTMGR missing’ and ‘Operating system not found’ errors.
This worked first time and it booted straight into Windows 7.
Thanks again

To Enter the BIOS press the 'Del' button on your keyboard. Alternatives are 'F1', 'F2', 'Insert', and 'F10'. Some PC's BIOS might even require a different key to be pressed. Commonly a PC will show a message like 'Press [Del] to enter Setup' to indicate that you need to press the 'Del' key. Some AMI BIOS require you to enable the option 'USB Keyboard Legacy support'!
For AMI BIOS:
Go to 'Feature Setup'. 'Enable' these options: 'USB Function Support',
'USB Function For DOS' and 'ThumbDrive for DOS'. Go to 'Advanced Setup'.
Set the '1st Boot Device' to 'USB RMD-FDD'.
Reboot the PC and it now should boot from the Usb Stick.
Go to 'USB Mass Storage Device Configuration'. Select 'Emulation Type'
and set it to 'Harddisk'. Go to the 'Boot Menu' and set the '1st boot device' to 'USB-Stick'. Exit the BIOS, saving the changes.
you can try 'Emulation Type' to 'Floppy' or 'Forced FDD'.
For PHOENIX/AWARD BIOS:
Go to 'Advanced BIOS Features'. Go to the '1st Boot device' and set it to 'USB-ZIP'.
