Solved Dell C521 Will not boot

[LazyLizard]

BIOS settings such as AHCI can cause a Win7 installation to fail where it
booted before. (I.e. AHCI on/off)

i may run into the CLASSPNP.SYS problem again, because Startup Repair did NOT fix it.

.

Where was the Active flag located before you ran Startup Repair repeatedly?

When you reinstalled, did you delete all partitions during install. Follow the same steps in Clean Reinstall - Factory OEM Windows 7 to get a perfect install.
