I am trying to dual boot, but I got this error.
But in review and install stage fedora automatically select the windows efi partion
, I don’t know that’s the reason for installation fails .
Please help me
I don’t dual boot, but as far as I know, you want one efi partition, and put all your entries in there. Then when booting, you choose which OS you want from the menu.
What is your reason for tryimg to create another efi?
And Welcome to Fedora 
Installing f43 requires that there be a 2GB /boot partition. Your screenshot shows 1GB for /boot/efi and 2GB for /boot so f43 should install.
I guess you meant that the boot partition needs to be 2GiB. The default for the ESP (efi) is still 600 MiB.
Before using fedora. I have pop os , pop os efi doesn’t use windows efi lack of space, only I have 100 mb efi ( OEM os ) so , that why I created seperate efi partion, that work well, and also fedora 43, I used fedora 42 . That also installed separate efi, from fedora 43 the boot partition space need 2 gb so I am decided to reparation and clean install, now it’s happens,
Additionally I am checked with using windows efi partion, now installation success but won’t boot os
If you want to dual boot, can you go into Windows and increase the EFI size?
Then the installer should be able to add a Fedora grub entry in there?
Do you have an Nvidia graphics card?
Yes I have
yep, I fat fingered that and fixed it above.
The third screenshot shows 1 GiB for /boot/efi and 2 GiB for /boot.
It also shows /dev/nvme0n1p1 to be mounted but not where to be mounted.
To be honest, the first screen shot shows an error message which doesn’t give any clue of what is wrong.
Maybe it’s related to that issue?
Now installation success , i can see grub
You can press “ESC” to hide Plymouth (that spinning wheel you see) and display the boot messages to check for any problems.
Alternatively, you can press the “e” key in the GRUB selection menu (the first picture), while selecting the desired option; a screen will appear where you can edit text. On that screen, you must find the text “rhgb quiet” and delete it; then press Control + X to continue with the initialization.
Both methods yield virtually the same result!
It shouldn’t take long to initialize, but every computer is different with its own hardware, which can ultimately increase the startup time.
When you follow the steps above, you will see a message indicating what is happening in the background, instead of that “pretty” screen with the spinning wheel.
Does a Live USB version of Fedora work?
Yes it’s completely working fine,
Mechine=acer aspire 7 nvidia GTX 1650 ,and intel i5 10th gen
At the end of the boot sequence there in the screenshot, does it hang - stay there and do nothing?
If so, can you go to a new TTY with ctrl+alt+f3?
Can you explain again your /boot and efi folder structure?
I’m a bit confused as to what you did to install it.
Yes, seperate efi 1gb . and seperate boot 2Gb. And remaining space root btrfs,
I tried also without manual partion, to use install alongside with windows option , that time also installtion successful, but the same boot issue occurred,
