I got this Dell Inspiron mini 10 with formatted C drive. There is a system-recover partition over 7 gb. Recovery ran and done really quick like within a minute. After that I am getting Bootmgr is missing error. Tried a fresh Win7 install from usb and getting Windows Boot Manager error saying to fix the boot manager. However the usb boots fine on the pc. I did install win7 from usb many times so I know the usb is fine. Dont have a optical drive so no suggestions for that please . Just wanna boot the usb and install win7.
