Hi I just installed ubuntu 12.04.3 on mt dell inspiron that was running windows 7. I had trouble installing it at the start so i used the

sudo apt-get remove dmraid

command to install alongside window. When i restarted the machine i got the

error: no such device: 4cfe3cc0-370e-48ed-82cd-7cd2ca7a0414. grub rescue >

message. Can you please help me fix my machine so it can boot either windows or ubuntu from the hard disk ?
