Hello,
I'm trying to run Windows 7 on my HP Elitebook 8560p laptop-- it shipped with a ~120GB ssd, but this drive proved to be faulty (separate issue) so I swapped in a ~250GB hdd from an older elitebook 8540p and performed a clean install of Windows 7 Professional 64-bit with verified-as-working source files. Directly after a clean install it will boot without issue (though it does take a little longer on the Windows logo screen than usual), but after installing the driver set it hangs at the Windows logo during boot. I tried starting in safe mode and found that the hang occurs specifically after loading classpnp.sys, which is just after disk.sys. I thought since I had recently monkeyed with the disk setup that this was likely the culprit... here's what I've done so far:
1. Ran Windows auto-repair, obviously it didn't work and identified a driver failure as one of the possible causes but found no root cause.
2. I ran sfc /scannow /offbootdir=c:\ /offwindir=d:\windows from a bootable Windows PE DVD (which assigns the host OS's system reserved volume c:\ and the system volume d:\ by default) and it found no integrity violations
3. I flashed the BIOS to the latest revision (f.27) and disabled all peripheral devices and ports, but this made no difference.
4. I tried a different hdd with a known-to-be-working Windows 7 installation, and hit the same problem
My next move is to perform a clean install on the most recent hdd and re-enable the various BIOS peripheral devices options to ensure I can still boot at that point. If that goes well, I'll start installing essential drivers one at a time with a reboot in between each to help identify the culprit. Has anyone seen this particular scenario before (trouble booting after making the switch from ssd to hdd)? Does anyone have any alternative/additional suggestions to what I proposed above?
thanks,
CCJ
