After waiting for hours I didn’t receive the activation key via any of the 4 email addresses I used. I can say that installing the app only adds files to the program’s folder, and adds 2 keys to the registry, one for the app & one for uninstall. The portable version, which is initially free, gives you several choices on what type of USB stick you want to create – it lets you create a USB stick for Legacy or UEFI BIOS, but not both, which is unacceptable… A few devices get confused when presented with both choices, but the majority will use the boot files they need, so the USB stick will work with a variety of hardware and the user doesn’t need two USB sticks, nor do they need to figure out which sort of BIOS a device has so they can make the correct choice.
There really isn’t a good reason why you might need FlashBoot, and additionally the product page makes a few somewhat misleading statements. It talks about transferring an installed copy of Windows, including installed software, to a new device. With Win10 you just need to clone the hard drive on the original system, or restore an image backup, and cross your fingers. Win10 will *try* to find and install any needed drivers, but Microsoft doesn’t have a copy of every driver out there, so in rare cases this won’t work. You’re more likely to run into compatibility problems from software installed by the old device’s OEM, though odds are this won’t be a problem. You will most likely have problems with at least some of your software deactivating – in some cases it might even do things like add registry entries to make reinstallation &/or activation impossible as retribution for trying to pirate the software. That’s because following Microsoft’s cue, very many developers tie hardware IDs to software activation. Some other software companies just keep track of the number of activations per key, so the software needs to be deactivated on your old hardware 1st.
Transferring a copy of Win7 to new hardware generally just isn’t going to happen, because drivers for things like USB aren’t available to Win7, and without keyboard or mouse you probably can’t add them afterward. Google and you’ll find a few potential workarounds that might or might not work. You can add drivers that should work to a Win7 setup image [.wim file], and there are tools from motherboard manufacturers to easily do that if you won’t want to go through the hassle of mounting the .wim file, adding drivers, then recompressing it. Unlike Win10, Win7 also does not look for new drivers once it’s installed – sometimes it’ll work, but often you need to run a special app to remove the old drivers that were installed, and then I’d put your odds around 50/50.
FlashBoot does do image backup & restore, but so does Macrium Reflect Free, which has a stellar reputation. Likewise, FlashBoot will create a Windows installation USB stick, but so will the Microsoft tool, & untold millions of users have used it successfully. FlashBoot will let you create a Windows to Go drive, but so will the Much more popular [& free] Rufus. There’s nothing special about a Windows to Go drive – it’s just regular Win10, usually on a MBR rather than GPT drive without the Recovery partition. You can certainly clone an installed copy of Win10 to a USB drive to make a Windows to Go drive, with all of the above potential problems, since software can deactivate, and you’ve got drivers & OEM software installed to increase the odds of compatibility problems. As at least one comment pointed out, USB sticks also kinda stink for Windows to Go – it’s really only workable if you use an SSD in a USB 3 [or faster] housing.
Related… some of the comments talked about the difficulty of booting to a USB stick or drive nowadays. Most devices have a hot key [often F2 or Delete] that when pressed repeatedly just after turning the device on will enter BIOS setup. One exception is our Lenovo convertible which has a special switch. Note that the device has to be off, not just sleeping or in hibernation. Win10 has a boot menu with options to enter the BIOS setup, but that menu is usually not visible unless Win10 fails to start 3 or 4 times in a row. You can use the free EasyBCD to add a boot menu delay, which will show the boot menu long enough to enter the hotkey for options like the BIOS setup. You can also get into the BIOS setup from Win10: laptopmag[.]com/articles/access-bios-windows-10
Note: Not every USB stick or drive will work to boot every device – there are possible hardware incompatibilities.
Note 2: Win10’s boot mgr. can interface with the BIOS and change it. When you’re in the BIOS setup and get to the page where you set boot drive order [the order in which the BIOS checks the drives looking for boot files, & the 1st boot files it finds are then used], you may only see the Win10 boot mgr. as an option – usually restoring default settings works to show all connected drives. Do remember or write down what you see on the page – you *might* have to put it back after booting to a USB stick or drive.
