Using Clonezilla, I cloned a Windows 7 installation from the first partition on one drive to the first partition on a second larger drive and then installed Ubuntu into the second partition (same configuration as the original drive, just newer version instead of old).

Ubuntu detected the Windows 7 partition properly and added it to the grub menu. However, when I choose the win7 option in grub, I just get a black screen and blinking cursor. How can I fix this?

@CentaurusA: Here is the output of boot info script output http://pastebin.com/778RP7Lp

Is the original hard drive still installed on the system? –  Mark Rooney Mar 5 '11 at 23:34
    
you may need to restore your Windows PBR –  Takkat Mar 6 '11 at 8:03
    
@Mark: Original drive is no longer present. @Takkat, I'm trying to find out if there is a way to do this without having to reinstall grub / ubuntu. –  bumbling fool Mar 21 '11 at 21:36

Try running Boot Info Script (http://bootinfoscript.sourceforge.net/). This will produce the file RESULTS.txt that describes each disk/partition on your system. Check that GRUB2 is identifying the partitions correctly by comparing the descriptors used in the menuentries in /boot/grub/grub.cfg match those in the results file. I have an issue where GRUB2 mis-identifies my Vista and Windows' recovery partitions and doesn't boot correctly as a result. The fix was to create a custom boot menu (see http://www.dedoimedo.com/computers/grub-2.html)

Thanks for your answer. My inexperienced eyes don't see anything wrong in the output. There are no recovery partitions of any sort either :/ –  bumbling fool Mar 21 '11 at 21:53

1. Boot from Windows Recovery CD, Windows Recovery Partition, or Installation CD

2. Click on "Repair your computer"

3. Click on "Startup Repair"

4. Windows should now boot properly

I was look for a solution that would not entail reinstalling grub again after repairing Windows. –  bumbling fool Mar 18 '11 at 19:13
