A problem that is taking me months to find a way to fix....

I actually have the bootable usb with me but when i try to boot from it with my dell laptop, it keeps saying "Operating System Not Found"

It sounds like the Windows 7 OS isn't on the usb stick maybe. I would start again. Format the usb stick to clear everything - so put the usb stick in the laptop, right click on it and select format. Then you have to make the usb drive bootable again and add the iso.

But I'm not an expert on this so follow the instructions on the previous post!

You cannot Boot windows 7 from a USB stick or even a USB attached external Hard drive. This Limitation is by design.

You can only create an Installer on a USB Stick, which will be much faster than a DVD.

You need to use a program to transfer the .ISO file to the Stick.

I recommend Rufus as It's never failed me

Btw i tried rufus but i the bootmgr is missing instead...

SO IMPORTANT: I found a way to go to the system recovery options thru the second windows 7 in the selection, do you think a dell factory image restorewill fix the problem and format the laptop back to its factory look? Also is windows installed already after doing the dell factory image restore?.

If you get a Boot manager missing error on a rufus generated USB stick it would suggest that either the .ISO file you are using to create the stick is corrupted and needs to be downloaded again or even from a different source, or another possibility is that you have not set the Boot option to ISO

btw what do u think about the factory reset? i need an answer for it since its my other option that i wanna try

A reset should solve all your issues, if it works, and it is not corrupted , it will remove the two copies of windows that you have on the system, any files you may have on the system will also be deleted, and you will probably find a bit of bloatware, (trial commercial software,) on the laptop after - it will install and activate whatever the original operating system was installed but it should at least be usable

Like instead of the present Windows OS im using, it will rather use the Windows OS installed when it was in the factory//store???
