I can't guess why you don't have this or if you can go get it from https://www.microsoft.com/en-us/software-download/windows7
It's a laptop so is the story about opting out of restore media? If so, order it now. And here it's never a problem since we took the entire office from w7 to w10. This way we can get an install stick anytime we wish without the CD KEY requirement.
Last week we used the last change W10 upgrade to catch up on a laggard employee.
That said, you could try EASYRE from https://neosmart.net/wiki/easyre/
My desktop PC has a 1TB Seagate Barracuda hard drive. Its separated into 3 partitions: #1 is System Reserved (100MB), #2 contains all the system files, and #3 is for personal files. The #2 partition is my C: drive and the #3 partition is my D: drive. The #1 partition does not appear in Explorer. A few days ago, I noticed the warning that my C: drive was nearing capacity. Then, it stopped booting properly. I was able to hit F8 and access the command prompt. After doing some research, it was suggested I set the #2 partition to "Active" which I did using the command prompt, and now it doesn't boot at all. I get the Bootmgr is missing screen and all I can do is access the BIOS screen. I pulled the drive from the desktop PC and have been able to access it as an external drive on my laptop. As an external drive, it appears as 3 separately labeled drives: #2 shows as the Active partition, which I believe is correct. The #1 and #2 partitions currently show <4MB of remaining space. I'm afraid to delete anything from those since I am not too familiar with those partitions, but I'm wondering if that is causing some issues. The #3 partition is 1/3 used. The #2 partition does have the Windows folder with a Boot subfolder. Is there something I can do to this drive while connected to my laptop that will fix my problem? Is it possible its getting ready to die, or do I need to create some additional space in the #1 and #2 partitions? Any assistance is much appreciated. I do not have a Windows 7 recovery disc or boot disc. Thanks!
