Windows 7: BOOTMGR is Missing During Windows 7 Install

Hi,
I'm attempting to install a copy of Windows 7 on a Asus Eee 1000HE. I downloaded the ISO copy of Windows 7 Home Premium from the Microsoft website on another laptop which I own. I then used diskpart to clean and partition my 16gb usb drive to NTFS. I then transferred the Windows 7 ISO to the usb drive. I then changed the Eee pc's bios setting to boot first from the usb drive. However, after rebooting I recieve the error:
BOOTMGR is missing
Press Ctrl+Alt+Del to restart

I've searched online to find a solution to the problem but haven't found anything that will help me out. Any suggestions would be greatly appreciated.

Thanks

go into your bios and change the settings

if you have 2 hd change it to the main drive

if you have a partion still change it to the main drive
