These are both Asus A53E laptops. I deleted all partitions and did my own factory install.
I wound up running through this troubleshooting guide:
https://wiki.fogproject.org/wiki/index.php/Troubleshooting_an_image_push_to_a_client
I learned that after dumping the MBR to the new box, my partition table was “invalid”- it doesn’t like my partition 5.
Once I deleted partition 5, I was able to go through with the rest of the steps and restore my partitions, sans #5. I’ve shrank that partition down by a couple gigs so it’s not touching the end of the device, and am making a new source image to try again and see if there’s some bug there.
FWIW, my partition layout looks like this:
1- 100M
2- 60GB
3- 208GB
4- (extended)
5- 30GB (now shrank to 25)
Is there a bug with extended partitions, maybe? For this purpose I need three usable partitions within the OS, and since we’re limited to three primary partitions and MS insists on that 100MB partition in the front, I think I’m stuck with it.
