Hi all,
I have two disks, each with a (OEM) installed OS on it, a Windows 8.1 (64 bits) and Windows 7.0 (32 bits). The later came from mine old computer that unfortunately died to soon. So I have two disks and two OS in an brand new machine (with UEFI BIOS etc.).
Installing a dual boot option was a pace of cake. However booting into Windows 7.0 gives following error:
"Windows failed to start. A recent hardware of software change might be the cause.
File:\Windows\system32\winload.exe.
Status: 0XC0000359
Info: the application or operating system could't be loaded because a required file is missing or contains errors".
There is lot discussions about installing two OS but that is not mine problem: both are already installed.
Also there is much rumour about the UEFI BIOS and support for older systems. In mine medion computer the Security Boot option is disabled (by the OEM), so booting from a old BIOS should be possible, must isn't.
Someone advised me to run the recovery disk (of Windows 7.0) and run Bootmgr. However the system refuses to boot from CD/DVD with the recovery disk of Windows 7.0 inserted, booting from the recovery disk of Windows 8.1. goes fine.
Removing the disk with Windows 8.1 installed on it and directly booting in Windows 7.0 fails too with the message: "Reboot and Select proper boot device or: Insert boot media in selected boot device and press key". Also in this case the system refuses to boot from the Windows 7.0 recovery disk.
Could you please help me?
