just installed Windows 10 on a seperate HDD on my home computer and ran into problems.
Till yesterday I was able to boot my Fedora system which was the only installed OS, now I installed Windows 10 to another drive and after a restart of the computer it brang up Windows 10 while sda where Fedora is installed was selected as first boot device. I booted up a Fedora LiveCD, reinstalled Grub on sda and was able to boot Fedora again. Grub shows an entry for Windows and after selecting it, it starts the Windows bootloader. But the windows bootloader gave me an error message, that files are missing. After reinstalling the windows bootloader through the Windows installation CD command prompt (bootreq /fixboot und bootreq /fixmbr, only fixboot did not helped), windows is able to start but again no grub...
It is an old pc with a BIOS, no (U)EFI I deactived hibernating in Windows, but it does not seem to help
How to solve this problem?
