I have tried the following:
- * Tried all combinations of settings for the guest
* Turn off DEP (and PAE in x86) for the host
* Clean Windows install (no drivers, no software, no windows update)
* Clean windows install with drivers
* different computers (All Dell optiplex ~3 years old - present) (Intel Pentium 4 Prescott through Intel Core2Duo)
* Turning off and on the hardware virtualization support for the computers that support it
* Older versions of VBOX (all of the 3.X versions)
* Newer Beta build (r56507)
* Turn off services on host (that are possible to stop)
* Used different HAL's on the host including ACPI Uniprocessor, ACPI enabled, and Standard PC
* Tried various suggested solutions like opening two guests simultaneously
Not entirely sure if this is useful, I'm not really a programmer.. I boot to a DOS prompt from a Windows-98 boot disk (CD-ROM iso). I see the following after reaching the prompt:
