Solved Bootloaders

[kmesbah]

I installed Ubuntu 14.04 LTS along side with Windows 7. I then, for some dumb reason, deleted the partition I installed Ubuntu on. I had Windows boot issues. I reinstalled Ubuntu and it works perfectly. However, I'm not able to see Windows 7 option on the grub menu.
I followed some steps online to fix Windows boot using Windows 7 installation USB flash drive. From the command prompt I ran:

bootrec.exe /fixboot
bootrec.exe /fixmbr

and these were successful. However, when I ran:

bootrec.exe /rebuildbcd

It did some work and found the Windows 7 installation, but I got the message at the end:

The requested system device cannot be found

I ended up getting my Ubuntu bootloader broken after this, but I fixed it using Boot-Repair.
Apparently, the message is because I'm using a Windows 7 installation USB flash drive. I can't actually use a DVD because my Optical DVD Drive is broken.
So is there any way to get things work properly using a USB flash drive?

here's my boot info
Thank you!

I solved the issue by plugging my usb flash drive into a 2.0 USB port instead of a 3.0 one which is not recognized by Windows when booting from a flash drive.
