So there was an update for windows 8 and after that it stopped opening the grub menus and it automatically goes to windows. I know it can recognize the drive with Linux on it because it shows it to me in file manager. Prior to that I unplugged and rep lugged the led plugs but I don't think that was the cause. So how do I show the grub menu? Thanks!
You can use EasyBCD to refresh the bootloader but word of advise, install Linux on separate drive and let GRUB Linux be the bootloader. I had problems before but now they're fixed after updating to GRUB 2.02
After I installed the WU W8.1 Spring Update I lost my dual boot menu (x6 OSs) all Wxp, W7 & W8.1, it would only boot into W8.1.1 (new upgrade) After trying the W8 DVD I tried the W7 DVD & selected repair boot manager(?). That worked & the boot menu now appears again so I can select which OS I want to boot into. I did have to remove the "Restored" portion after each entry, I used DualBootPro to do this. HTH
That's what that "Drives" drop-down menu is for (assuming you know the /boot partition)... if you want directions to boot using GRUB instead post details in the Linux forum...
