Boot disk error with cloned win 7 64 bit on ssd - why?

Hi guys.

I installed my sandisk pulse ssd 256gb sata iii on my sata ii moo via pcie sata iii card. every now and then I get the boot disk error messages - CTRL-AL-DEL to restart . I set it as my primary disk boot and disabled the wd blue from appearing on bios hasrd disk selection (which also has os installed)

I know I don't get sata iii speed on my mobo but am more worried about boot disk error messages.

any fix for this? should I reinstall my win 7 ultimate 64 bit upgrade on the ssd and start afresh? at the same time save all data to external hdd and wipe the OS clean off the wd 500gb - then copy all music and sundry back to the wd blue?

I plan to get windows 8 asap while the upgrade version is on offer till end of January 2013.

after my hardware plan works will a clean install of windows 8 pro upgrade wipe my ssd clean fixing the problem?

please help and merry xmas and happy new year

Check your BIOS manual for setting to boot via PCIe sata card, for Windows 8 will need full support to via PCIe sata card.

done that. no help what so ever.

I think so too big MC. tell me.i am getting the m5a97 le r2 next week. if I install my current ssd and win7 on it then there after bios updates and all are done, I install the windows pro 64 bit version. should be okay from there? have a merry xmas and happy new year

thanks. I will do my best to keep her nice and tidy- especially the wiring part as the new mobo will have two extra case fan headers on pwm I hope and think. need to check online manual again.
