1. I agree and unless I have it wrong which I do not think I have that motherboard is NOT capable of supporting windows7http://www.intel.com...b/CS-008326.htm
2. Additionally unless the ram has not been correctly reported you only have 1Gb of ram and that is NEVER going to satisfactorily run Windows 7, with a triple boot configuration and two hard drives one of which is a Tb .
3. I do realise that these aspects are not directly related to the problem, but I am of the opinion that you are trying to configure a system setup that is incompatible with the capabilities of the computer
4. Personally, if the system was mine and AFTER trying as my colleague Amlak
has suggested AND waiting for the opinion of my good colleague phillpower2
I would, providing of course that you do have an image of the windows 7 installation, or at least a backup of your data, and possibly the latter is in this case preferable, depending on when the image was created.
5. Scrap the idea of a triple boot, with two XP installations, one on each drive, and consider starting again
I would explore the conmpatability of that computer to run windows7 on the version you are using on this link here.http://windows.micro...upgrade-advisor
using that of course whilst you have the capability to do so, in otherwords before you start the clean install of the new systems.
6. I would if that result is favourable upgrade the ram from the IGb to 2Gb if that is the max capacity of the board. - but not of course before you have satisfied yourself that the board is OK.
It seems unlikely, but I am wondering if something has been damaged in the failure of the UPS - depending of course on how this failed.
7. I would then install Windows 7 on the 1Tb drive., either a a clean install or trying first the recovery from image
8. If you are set on a dual boot with XP, do please remember, and I have mentioned it earlier about the deletion of restore points, on Windows 7, when you boot into XP, installed on the same DRIVE.
You can get round that problem by changing a registry keyhttp://support.microsoft.com/kb/926185
9. You may consider, if you manage to get the Samsung drive bootable and working, installing XP on there, but as a separate installation and not configuring a dual boot.
Then using F12, as the one time change of boot priority order - when wishing to boot to the samsung.
10. Or once you have 7 installed on the Western Digital and depending on the edition of the 7, you can use thishttp://windows.micro...de-in-windows-7
that is if you have the right edition of 7, not just an XP compatible mode, but a full working setup of XP.All of my post is really for AFTER you get the results from my colleagues suggestions.
