Windows 7: Windows won't boot and more

Yes I tried safe mode, safe mode with command prompt, all of them and just after it leaves the windows screen it shuts down and restarts, then asks again what I would like to start windows in. It seems to happen just as the DVD drive light comes on. Could this be an issue with it, but even when it is unplugged I still have problems.

Still sounds like a driver issue to me. Anyone else have any ideas?

If it is a driver issue, how do I get rid of it when all my drives are unplugged and still no luck. I don't understand how neither OS would load up at all if there was a corrupt driver.

Did you delete pxhelp20.sys ?

When you say the Drive letters changed - did you see the change from within windows, or is that how Diskpart sees them?

Drive letters viewed from WinRe are not necessarily the same as they appear in Windows.

Not sure how to delete from the command prompt, but was going to try that. The last time I went to the command prompt, that even seemed to be giving me problems and I had trouble viewing some directories. I was able to find the pxhelp20.sys file, now I am having trouble getting to that directory. The drives show up that way in the windows repair screen that comes up ever time. Is that winre?

Yes, that's WinRE.

You might be better using the Paragon Rescue Kit Express (RK9) - it's free and burns itself to cd ( don't format the cd )

Boot that, select Normal Mode , then File Transfer Wizard - browse to the locaton of pxhelp20.sys, and rt click and delete.

You can also see if it shows the drive letters as you expect - you will see them as windows does.

If they are different ( I think you tried to change them already) - then you can use the boot corrector on Paragon to change them back to how they should be as you remember them in Windows.

There is a Boot.ini corrector on there - works only the XP installation, and a bcd corrector - that will correct a Vista entry, but won't affect the 7 entry. ( I am sure RK10 will correct 7 entries, when it comes out).

Have downloaded the paragon rescue kit, booted up with the cd I made and am first doing a file transfer to copy my picasa albums, firefox and thunderbird profiles and just few files on my partition that I hadn't yet backed up. Thanks for the info and will report on the outcome. If nothing else I have those files now if I have to do a clean install. I just wish I new the problem for sure so I could avoid it in the future.

I installed software that came with my Sony Handycam HDR-SR8 and ended up with the same symptoms - W7 would not boot. Here's what I did.

Use command prompt to rename pxhelp20.sys to pxhelp20.bat
Now it should reboot but it might be that you don't have any CD drives working so...
Edit the registry key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

Rename the line "LowerFilters" to "LowerFilters.bak" if it has pxhelp in it. Reboot and that should be you sorted.

SIW2's solution worked for me. Paragon Rescue was just what I needed to first make sure all my files were safe a backed up. Then I deleted the pxhelp20.sys file and voila, windows loaded up and all was just as it was. Thanks for the help and for the tip on a great free rescue program. I believe the culprit was Roxio Easy Media Creator 9. I ordered Creator 2010 and hope it will work for me. My Sony Software works just fine without that file

Hi digi,

Thanks for posting back your results.

I hope Creator 2010 works better for you.

Probably worth making a backup image - just in case. Or , in fact making one regularly is a good idea - you never know when you might need it.

This Paragon Freebie works very well for that:
