I have upgraded the hard disk in a Samsung laptop and would like to restore the "Press F4 for recovery" partition.

My new disk has three partitions, System, Windows, and Recovery. I did a dd of the recovery partition from the old hard disk to the new. I also set the diag flag on the new hard disk. F4 recovery still is not working.

TLDR: I mapped my new disk like my old disk with the exception of exact sizes. I did the recover partition from old to new via LiveCD. F4 recovery does not work.

    Did you duplicate the original hdd sector by sector or only selected partitions. It sounds like the process you used was incorrect.

  • The selected partition. The new hdd is smaller. I did "dd if=/dev/sdc3 of=/dev/sda3 BS=512". Why would you have to clone the entire disc? You should be able to split or trash your windows partition and have it still work

  • You clearly did something wrong, because it doesn't work, which is the reason I would copy the entire disk.

  • I got it. I am going to do a writeup and post all the tools. I basically found this Samsung utility that is a boot-able version of Samsung Recovery. Using that I can repartition the HDD to Samsung's liking. It installs a base recovery environment and restores press f4 ability. Then I installed windows and used linux to copy the original recovery partition back (on a file level, not dd). Check back here in a few weeks.

    I’m voting to close this question because the original poster claims to have solved the issue and would post instructions 11+ years ago but never did. This question is effectively orphaned. “I am going to do a writeup and post all the tools.

When I need to migrate a HDD to SSD. I use the Samsung Data Migration Software. It's a great tool for moving all your partitions.

You will need to use dd to do a full drive copy to this one and then use the recovery, as it sounds by doing only one partition, the MBR isn't being copied correctly, preventing the recovery from working.
