Running Windows 7 in a RAID 0, and periodically I will get a boot failure error with the message No default or UI configuration directive found. This usually happens if I do some kind of heavy maintenance on my system. For example I might remove my graphics card or cpu cooler to blow the dust out of it. The other day I replaced the RAM and that triggered it. After doing those kinds of things inevitably when I go to restart I get this boot failure and message. So I go through the same process every time of booting to my Windows 7 repair disc and running automatic startup repair and most times that fixes it on the first attempt, but sometimes it takes 2-3 runs of the repair tool before it will boot normally again. I googled the phrase "No default or UI configuration directive found" and found very little on this issue pertaining to Windows 7. Seems to be a big problem for Ubuntu users and people trying to boot to USB devices. Can someone help me with this? I feel like I'm always walking on thin ice with this system. I've done it so many times now that I'm almost accustomed to it, but it's actually got me pretty nervous. Help please.
