Messed up mbr what do I do? I need data in my home dir...
 

I need to fix my netbook. I had trouble booting into windows on a dual boot eee pc with ubuntu10 and win7. as such i couldn't get into win 7 and decided to run a boot cmd and it jacked my mbr.

now it won't start and as i type this won't turn on. this is one bad day.

Don't panic.

Just get a boot CD and fix your MBR :)

Here's one guide:

And another:

Alternatively, "SuperGrub2Disk" might be just what the Dr. ordered:

Worst case, you could always mount your Windows install CD, go into rescue mode, and run "fixmbr":

It all depends on:
a) what resources you have available (although I *hope* you have at least *one* install CD, and a working CD/DVD reader)

b) what you feel most comfortable trying

try to fdisk /mbr,then reboot if you can reboot into win7, download a grub4dos,it can be used in windows

thanks peeps
