Did you install CentOS in UEFI mode? Is Win10 in UEFI mode too?
Re: cant see Windows 10 on grub screen at the beginning.
Yes, both Centos 7 and Windows 10 are installed in UEFI mode.

Re: cant see Windows 10 on grub screen at the beginning.
When you start the machine and press the F9 (could be different) - the boot menu for the bios , is there an entry for windows and CentOs, or just CentOS?
If your need your windows urgently, you can run the windows dvd and select repair.

I can see just CentOS. I tried to repair Windows but it didn't work.

I think Windows 10 is deleted when I try to install Centos 7 again and again. I cant see Windows 10 in folder, other locations.

Re: cant see Windows 10 on grub screen at the beginning.
Yes, same as in viewtopic.php?f=47&t=64199 . The UEFI boot entry is there but no folder called /boot/efi/EFI/Microsoft containing the MS-Windows EFI boot loader, so you have accidentally advised the CentOS installer to re-format the EFI System Partition (ESP).Cagatay wrote: BOOT centos
Restoring the MS-Windows boot loader should help.
BTW: Since this seems to happen quite often to people I would recommend a change in Anaconda: If a user ticks "[ ] format" on /boot/efi, it should raise a warning message that this is usually not necessary and especially will wipe out other, already existing EFI boot loaders.
