PassFab FixUWin is a cool tool set on a bootable USB stick that works with UEFI & Secure Boot. That last part is important, because you'll sadly find all sorts of bootable USB sticks that can't, e.g. AOMEI, EaseUS, MiniTool etc. That said, if you don't mess around with adding/replacing hard disks/SSDs, Partitions, &/or Windows when it breaks, you can skip this GOTD in good conscience. FixUWin is basically Tenorshare's Windows Boot Genius under a different label, so if you're hunting for online reviews, Google that. 4ddig.tenorshare[.]com/windows-boot-genius.html
I ran a 7-zipped copy of the program's folder through Virus Total, getting 3 hits: Malwarebytes, MaxSecure, & VBA32. When I later did the same thing for Boot Genius Malwarebytes didn't flag it -- maybe they updated their pattern files between the 2 runs? Installing FixUWin adds the program's folder, plus a folder in Users\ [UserName]\ AppData\ Roaming. In my Win11 VM I recorded 4 new registry keys. The app itself just downloads the files and puts them on a USB stick, or you can use a DVD, so it's well suited to run in a VM without bothering your regular copy of Windows. When you boot to the USB stick you see all the utilities on a screen that's similar to Windows. The two you're most likely to need/use are the Windows password reset & the boot repair. The password reset isn't that big of a deal -- Google & you'll find all sorts of how to's, tutorials, & tools -- but the boot repair, *if it works for you*, could turn out to save you hours...
Windows boot files [BCD] are complicated. There's a separate BCD registry hive that can record & store data about SATA SSDs & NVMe drives. When you install a fresh copy of Windows it handles that just fine, creating matching boot files. However, the boot files that had been working perfectly on another drive often just won't work if you move them to a new SSD or NVMe drive. Windows' own tools, BCDEdit & BCDBoot, usually won't help. And editing the working boot files after installing a fresh copy of Windows, e.g. to add a 2nd OS to the boot menu, may or may not work, using either EasyBCD or BCDEdit. Paragon HDM & Macrium Reflect USB sticks have boot repair & migration tools that *may* help, but not always. AOMEI has something similar but since their bootable USB sticks won't work it's irrelevant. FixUWin gives you another option.
