I installed a PCI Magic Card on my system. It installs grub bootloader (I presume). When it tries to boot I get the following:
Boot failed! Press any key to enter command line.
I'm using Windows 7. Is there a way to solve this issue?
You could try using boot-repair: You can get it in 2 ways, on a live CD and on Ubuntu and probably some other Linux distros:
boot the CD and choose recommended repair
Download Ubuntu Live CD here and burn it on CD, or USB
boot your computer on a Ubuntu live-CD or live-USB.
choose "Try Ubuntu"
open a new Terminal, then type:
Press Enter and then type:
If that doesn't work, you might want to re-install Windows.
if you want to preserve grub, get a linux live cd (preferably Ubuntu) and follow the instructions here http://www.howtogeek.com/howto/ubuntu/reinstall-ubuntu-grub-bootloader-after-windows-wipes-it-out/
