A friend at work was trying to play Master Geek on his HP Omnibook 6000 running Windows XP Pro and deleted two files and one line of the registry and OOOPS, the blue screen of death on start up. It gives a 07B stop error. The files he deleted were for iomega drives. I offered to find a solution before he has to admit he messed up to the company computer crew.

I am hoping to use the XP Pro install disks to get in and reinstall XP tonight, but I think I will wait and see if anyone here has some ideas before I do my dirty work on it.

The system posts fine and it will not go into safe mode or restore to the last known good configuration. They all go to the blue screen. Even when we try to use a boot disk to get to the dos prompt we can't see the C drive but when we do an Fdisk on it you see the NTFS partition.

We hope to go in to use the recovery control panel if we can get to it, but when we tried this morning it went to the blue screen before it booted up.

If you have any suggestions other than reformat and reinstall to try and save the wrath of Kan on this poor fellow let me know.

Here is a copy of the post on HP's forum

"Using Regedit
Export this key first:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E967-E325-11CE-BFC1-08002BE10318}

Then delete the string named
"LowerFilters"
The data in this string is Iomdisk

Reboot and try again on install. Apparently after spending $25 on tech support they "shared" this tidbit with me.

The string "Lowerfilters" and its reference to iomdisk has been mentioned for another photosmart printer in the forums. The file iomdisk.sys is installed by iomega for zip, peerless disk, and other mass storge by iomega. This file tries to control disk naming. You may also want to rename or delete all the instances of this file on your system as well. Be cautioned to back up and record all the edits mentioned above as corrupting a registry is a terrible thing. Good Luck. This worked for me but no gurantees or warranties are expressed nor implied."

Yes, screwing with the registry IS a terrible thing.

Thanks for your time and efforts.

Always before mucking about in the registry.....MAKE A BACKUP!!!!!!!!!

Before you go any farther check to see that the zip drive is not listed in the BIOS a boot drive. Basically make the chain hard drive fist then CD, then any other choices.

It seems for some reason that XP thought these zip files were tied to a bootable device and no it not there, so you are getting the stop error.

With the XP install CD we were able to "repair" not reinstall XP on the system and no data was lost. We restored the files we renamed but that was not enough, the registry had to be repaired.

Good ending to a potentially damaging situation. Like they said, messing with the registry can be dangerous.

FYI---if we removed the iomega active disk program the printer installed just fine. A better way to remove files.
