After Win 7 Upgrade to Win 7 Home Prem 64 bit see Disk Boot Failure intermittent.
I upgraded a HP Pavilion Slimline from Vista 64 Home to Windows 7 Home Prem 64 bit.
After the upgrade I see that on some reboots the error "Disk Boot Failure" and the system stops. at this message. I hit the power button and the system boots normally.
Any ideas what the problem could be and how to resolve this?
