Windows 10: Why has my laptop opened in "BOOT MANAGER"? Windows 10

When I powered up just now 07:50 here the screen was showing a screen on which the text was showing something on the lines of the following***:


BOOT MANAGER

BOOT Option Menu with two options:


Windows Boot Manager 'Samsung' followed by 17 alpha/numerics

EFI Px Network followed by 6 alpha/numerics

up arrow and down arrow to change option. ENTER to select an option


I pressed Enter on the top option Windows Boot Manager and was taken to my usual first screen Searchlight where I as eventually asked for my Windows Hello PIN number and I'm now able to ask this question.


What caused this? Was it anything that I've done or haven't done? Do I need to change any settings please?


*** PS I couldn't take a screen print of course.

PPS I'm not sure if I've selected the correct topic & subtopic. If they're wrong would a Moderator please move this? TIA

:)

 

Windows 10 Tweaks

Pressing “Windows+Pause Break” (it’s up there next to scroll lock) opens the “System” Window.

Windows 10: In the new version of Windows, Explorer has a section called Quick Access. This includes your frequent folders and recent files. Explorer defaults to opening this page when you open a new window. If you’d rather open the usual This PC, with links to your drives and library folders, follow these steps:

• Open a new Explorer window.
• Click View in the ribbon.
• Click Options.
• Under General, next to “Open File Explorer to:” choose “This PC.”
• Click OK

No Windows Boot Manager on dual boot system (7 & 10)


I thought I'd just post a little guide.

This is the only thing that worked on my ASUS N55SF dual boot system: Win7 on HDD (MBR) and Win10 on SSD (GPT).

Step 1
Assuming that you have already Win7 installed on your primary disk, install Win10 on your secondary disk.

Step 2
When install is done, enter your BIOS and go to the Boot section. There you should see "Windows Boot Manager" as your default boot option. Change it so that your primary disk (where you have Win7 installed) becomes your default boot option (it should be something like "P0:" followed by your disk model number, mine is "P0: ST9750423AS"). Save and restart.

Step 3
Now Win7 should start automatically (no boot manager showing up). Enter Win7, open an elevated command prompt and run
bcdboot X:\windows
where X is the Win10 system partition as seen from Win7, typically E, F, G or H.

Step 4
Restart. You should now see the Windows Boot Manager (probably the Windows 10 GUI boot manager). Select Windows 10, install your audio drivers (if you already have, I suggest you uninstall them and restart before doing this), restart and you're done.
