Loads os from scratch when waking up from standby

I have run into a peculiar problem lately.
I have an old Compaq C510 computer. I installed W7 a while ago, but keept the original xp so I have a dual boot system. It seemed to work very well, both standby and hibernation worked on both os.

A few days ago I replaced my hdd with a brand new 1TB disk. I had some problem cloning the old disk. First I used Aomei which I have used quite a bit before with good results. I used the function "Move os to new disk". However this function only moved one os or partition at a time, so I had to do this move twice to move both os. But then only the last moved os was accesible even if I still had the "which os to start from" selection at startup. I then tried the cloning function with Acronis from WD, but this program didn't work at all. I next tried Macrium Reflect and this program did the job of cloning the old disk into the new one in one go without even restarting windows to acomplish the task.

All semed good when I booted from the new disk, I could choose which os to boot from. But then I discovered the pecularity, in W7, both standby and hibernation still woorks, but in xp, when I set the computer in standby it seemingly enters standby correct, the fans stops, screen go black and my power light starts blinking. I can wake it by keyboard and mouse, all good. But when I wake it, the os load from the beginning as from a cold start. I can enter bios setup and nothing of what I had open when entering standby is saved and reloaded.

Can anyone shed some light on what could be wrong here?

No one have any sugestions here? What are the inner workings so to speak of the standby funktion, is some information written to a file before entering standby? I would suppose the main board is retaining the data in the ram as the same main board works in W7, and besides, I can wake it normally by keyboard and mouse. But then, what causes the bios to start loading the boot sector on the hdd instead of the normal activation algorithm?
