STOP 7B error during boot up

Hi,

I really need some help here. I posted previously about USB flash drives,
but now the problem seems more serious than that.

The system I am working with has an IDE hard disk. The HDD boots up in XPE
SP2. Sometimes, if a USB flash drive is plugged in, the system is unable to
boot up in XPE and results in a STOP 7B error. The BIOS recognizes the flash
drive as a hard drive.

Now, this is also happening when a PC card is inserted into the system,
which the BIOS also recognizes as a Hard drive.

This is really strange. Both USB flash drive and PC card work fine if you
plug them in after XPE is booted up. And this error happened at times only
(but if it happened once on 1 image, it will happen consistently.)

Is Windows trying to boot from the USB flash drive or PC card somehow even
though XPE is only loaded in the HDD? The 7B error happened when Windows is
loading (at the colorful Windows logo). What can I do to prevent this from
happening? Is there some registry settings that should be deleted?

Please help me as I really have no idea why this is happening...

Thanks!

I can't see how. The USB drive and PC card don't have bootable
images on them, do they?

Have you tried disabling all boot options apart from HDD in
BIOS?

What motherboard are you using?

Hi,

The devices do have bootable images, but all non-XPE. Booting up is fine if
I disable the USB or PC Card from the BIOS. I am using an Intel motherboard.

FBA was run using a normal HDD, but the actual usage is actually on a IDE
flash drive. I did a quick check and it seems that the problem didn't happen
(at least just now it didn't) if I used the same image on a HDD instead of
the flash drive. Could this be the reason why?
 
Hi, some updates...

It was probably not because of the type of IDE disk, but rather, if a disk
had encountered the STOP 7B error, even restoring a new image wouldn't
totally clean the disk. (A possible application error from the image
restoration part).

Anyway, I reghosted a new disk again with the very same image and found that
the image boots up fine with both USB drive and PC card plugged in. However,
if I go into BIOS and switch to boot up from my USB thumb drive that is
running DOS, and then try to boot up into XPE again using the IDE drive, the
STOP 7B error occurs.

Did a bootlog, and found that the USBSTOR.sys and fastfat.sys were not
loaded. It doesn't seem to be a missing component issue here. How else can I
isolate the problem? Could this be due to some corrupted registry files? Any
one has any experience on how to fix this?

Many thanks!
