Solved Dual-boot windows 8 and Windows 10 but no GUI boot manager

[ajay250496]

I have recently installed windows 8.1 onto my previous installation of windows 10 (upgraded from laptops factory windows 8). Both OS's work perfectly fine however i am faced with a problem where i get the legacy boot menu. My problem is i can't get the standard windows 8 GUI boot manager rather i get the legacy boot menu and sometimes my computer even decides to skip the boot menu and load straight into the default OS.

I have done some BCDEDIT commands and i set it up. To me it looks perfectly fine but the boot manager doesn't reflect that. Here is a screenshot of the bcdedit oiutput.



As you can see boot manager is set to standard which is the GUI boot manager. I cannot seem to figure out the problem here. I have already posted in another thread and i could not get a solution so i decided to start my own thread.

One thing that i should mention is when i was installing the windows 8 it did give me a warning about the recommended order for partitions for GPT. However i ignored it and saw no real problem in how the OS runs or booting. Only the boot manager but here is a screenshot of diskmanager



Any help is much appreciated.

Windows 10 and Windows 7 dual boot system (see screenshots below).





Take a look at this post: dual boot win 7 and win 10? - Windows 10 Forums

Open Admin Command Prompt and type: bcdboot %windir%
will rebuild the BCD and gives you back the GUI.

Thanks, it works perfectly.

That's a useless error message, so this error message can be ignored.

I've had the boot menu reset to legacy mode from time to time and when that happens, the two commands, run in an elevated command prompt, fix it:

bcdboot c:\windows

or

bcdedit /set {current} bootmenupolicy standard

You will notice the OP's boot manager states "DisplayBootMenu" "Yes"
and the reply does not show "DisplayBootMenu" at all

"BootMenuPolicy" "Legacy" allows display of F8 boot menu option

I ran the commands and they all said they were successful. However i STILL get the legacy menu,

I even turned off the fast startup in both windows 10 and windows 8.1.



I have no idea whats wrong. The bcdedit command does not reflect on what actually happens on boot up. Does this mean its corrupted? I've been looking around on how to manually rebuild it. However all the tutorials i find online work up until a point where im supposed to execute the command:
attrib c:\boot\bcd -h -r
and then further renaming the BCD file then renaming the BCD file and rebuilding it with the bootrec command.

However when i run the command I get the error: Path not found

I ussually run the command on a windows installation however for the illustration purposes i simply did it in windows 10 because i did not want to go and boot a Installation.(lazy) It is the same exact error.

This is the link to the tutorial: How To Rebuild the BCD in Windows [10 to 20 Minutes]

Im not sure what to do at this point. Is is because the BCD store is stored in a different place?
Im king of convinced that the BCD might be corrupted however it looks perfectly fine to me, yet i have no idea why it shows the legacy menu.

try this
From an elevated command prompt type> bcdedit /set {bootmgr} displaybootmenu False

 

[ajay250496]

try this
From an elevated command prompt type> bcdedit /set {bootmgr} displaybootmenu False

IT WORKED! I spent so much time on such a simple fix. Wow.
Thats weird though doesn't the displaybootmenu key means if the boot manager should be displayed or not??

NOTE: I also had to keep the fast startup unchecked. If i enable that then the PC will automatically load the last OS i shutdown.

So you get now the GUI ? But what did you do get this ?
"bcdedit /set {bootmgr} displaybootmenu False/true" and "bcdedit /set {current} bootmenupolicy standard" does not help !?
