I need the SP1 on Windows 7, but I get always an error when I want to install it. I read that it is because I have a dual boot Windows 7 + Ubuntu. And after installing Ubuntu, GRUB2 overwrote the Windows 7 mbr or something like that. So I wanted to fix it. I read that you should boot Windows 7 with a DVD, then click on Windows repair and then in the cmd write the command 'bootrec.exe /fixmbr' to recover the Windows mbr and delete GRUB2. But after restarting my PC - no GRUB2, but also 'missing operating systrem'. So what should I do?
UEFI + MBR 安装WIN732
I have my Windows 7 x64 ISO on my pendrive, but WinToFlash app forgot to install the MBR (again). The only PC I have, uses x86 Win7, so it won't install the bootrec.
I hope you can help me. Thanks in advance!
