I should have come here first, but for several weeks, I started having serious crashing, freezing, then the dreaded BSOD on my upgraded Windows 7 PC.
Finally it wouldn't even boot back in Windows 7. I could not find my Upgrade Disk or Repair Disk at the time, but I had a Ubuntu Disk. So I foolhardy installed Ubuntu on a 2nd HDD in my system, think I would be able to fix Windows 7 later.
Now I've found the Windows 7 (upgrade) disks. But I can't repair Windows 7 nor can't figure out how to re-install, it doesn't give me that option, that I can find. I've removed the Ubuntu drive, but Grub is still installed.
I would like to do a clean install (since I have already backed up my important files using Ubuntu).
Will following this: SSD / HDD : Optimize for Windows Reinstallation
do the trick?
Once I get it re-installed, and if it crashes again, I'll do the memtest and other troubleshooting found here.
