First of all, the boot device is an 16GB SD card. I install Citrix XenServer on it but I make the partition too small (XenServer makes a lot of logs file). I resize the partition but now it give "Illegal OpCode" and red screen everytime it boot.
I already create the image of the whole SD card using dd and already try these process three times = restore the image, test that it can boot properly, then resize the partition using gparted, then it can't boot.
I already post this question in XenServer forum
(with screenshot) but nobody answer there.
The hardware itself is HP Proliant ML350 G6 with internal SD slot.
Any help will be appreciated.
