[Bug-ddrescue] ddrescue and bad IPL

[Ole Reier Ulland]

It is not because I know that I have uncovered a bug in ddrescue that I send 
this e-mail, but 
because it is the only way I know how to communicate with people who know 
ddrescue well.

I want to be able to make image files of my bootable partitions as back-up 
files. But for that to make any sense I have to know that I am able to boot 
them after using the image file again to restore the partition.
 
I have made a test. I use a computer with two harddisks. sda with Windows and 
sdb with Mageia Linux. I "ddrescue" the Windows partition to sdb3, primary 
partition, and use fdisk to set the boot flag for sdb3.
 
I have installed grub2 on both sda and sdb. grub2 probing finds both Windows 
partitions which now has the same UUID, but different PARTUUIDs. Both grub2s, 
trying to boot sdb3 just gives a blinking cursor in the upper left corner of 
the screen, and I have to shut down with the power button.
 
Reinstalling Windows bootloader to sdb and booting with it changes the result 
to "Bad IPL Any key to reboot", but I still have to use the power button the 
shut down.
 
1. Is the cause of the problem with ddrescue?
 
2. What is going on?
 
I would very much appreciate your ideas.
