Hi guys I am having trouble with installing windows 7 using a USB stick. To create win7 bootable drive I have the diskpart approach, widely available on youtube . Now when I insert my usb and set bios to boot from usb I get the BOOTMGR is missing error. I have attached the snapshot of the same. This error does not come when I try to boot from cd drive (however that approach is giving some other issues ). Can someone please help me with this issue.
