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?

"It installs grub bootloader (I presume)." Are you sure about this? The description on the manufacturer does not say anything about this. – Michael K Feb 22 '11 at 11:53
@Michael It's definitely grub. – Amir Rachum Feb 23 '11 at 16:45
Which installation option did you choose? Did you set the card as your first boot device in BIOS? – Tog Feb 14 '12 at 10:51
Try to enter that command line and issue those commands: root (0,0) (or in Grub2: set root=(hd0,1)), chainloader +1, boot – gronostaj Feb 26 '13 at 10:14

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:

1st option:

get a CD including Boot-Repair here

boot the CD and choose recommended repair

2nd option:

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"

connect internet

open a new Terminal, then type:

sudo add-apt-repository ppa:yannubuntu/boot-repair && sudo apt-get update

Press Enter and then type:

sudo apt-get install -y boot-repair && (boot-repair &)

Press Enter

type boot-repair into Terminal and choose Recommended repair


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

It seems to me that Grub is fine, but Windows is out. – gronostaj Feb 26 '13 at 10:12
