Prior to doing a Microsoft W7 course I set up an installation of Windows 7 professional installed in partition C of a new two partition drive.
I have my XP professional installation set up on my original drive and simply booted from W7 by either selecting the alternative drive from the boot menu on firing up the PC, or actually disconnecting the XP drive and connecting the W7 drive. This worked fine during my course, but when I tried to load up the W7 drive a few weeks ago it black screened as above.
I have looked at the experts suggestions for this type of problem and tried all the remedies as far as I can see, but no luck.
I have my Adobe CS4 installed on this drive and wish to de-register it so that i can use the software on another machine but unfortunately can't get at it as windows does not boot.
I've tried the fixboot/fixmbr/rebuildbcd etc, tried repairing using the Windows7 DVD, even tried sfc but wouldn't complete as waiting for completion of the repair, and needs to run from within windows.
Alt/ctrl/del or esc doesn't come up with anything.
Safe mode gets as far as classpnp.sys before going to a black screen (which may be normal) but then hangs with the same problem.
I couldn't restore to any earlier point as I usually do a backup using Acronis. Recovery of the last backup using Acronis results in the same black screen problem.
I have recovered the Acronis images to two different drives- same black screen problem arises.
I've tried two different PCIe graphics cards- still same problem so not likely to be graphics memory. Drive tests as ok as does memory.
I have successfully restored my first Acronis backup taken just after installation/updates so think it may be a subsequent update. It was working ok last time I booted it up earlier in the year but cannot remember if any updates were installed on closing down.
I'd be grateful for any suggestions as to how to resolve the problem.
