AFAIK the key to enter the BIOS/UEFI boot menu on an Acer computer is F12 during POST.
Hi

To enter the bios and change the boot order first to USB (iso with windows) I had to disconnect the power cable, after that I pressed F2 and it worked for my acer.

After that create a new boot file for windows thanks to this tutorial: https://www.youtube.com/watch?v=Z6KIV8vvkCg&t=5s

Then I rebooted but when entering Windows 10 I get the following error messages:

Code: Select all

error: file /EFI/centos/x86_64-efi/ntfs.mod not found
error: invalid EFI file path
What can I do next?
I feel like I'm very close to solving it with your help.

But that didnt not solve the problem
Installing the ntfs support is only a prerequisite to fix the problem. The next steps are to check if os-prober is now able to find the Windows installation, and if yes, to regenerate the CentOS boot menu:

1. What does

Code: Select all

os-prober
say? Does it find the Windows installation? If yes, continue with step 2:

2.

Code: Select all

grub2-mkconfig -o /boot/efi/EFI/centos/grub.cfg
(as root) [1]

Now you should have an "MS-Windows" boot entry in your CentOS boot menu.

I repeated these steps again and the problem was fixed. I already have Windows and Centos together.

Thanks friends
