Note: This appears to be a problem with Windows 8, no matter what host OS Virtualbox is running on.

I recently tried to install Windows 8 RP 32-bit in Virtualbox using Ubuntu 12.04 as the host. I have tried multiple settings for memory, hard drive size, etc. Every single time it has come up with this error

Your PC needs to restart.
Please hold down the power button
Error code: 0x0000005D
Parameters: 0x0306170A, 0x756E6547, 0x49656E69, 0x6C65746E 

I really like windows 8 and I would like to know how to fix this some time soon.

Check your BIOS settings, specially, the CPU related. – Mitch Jul 1 '12 at 5:03
This should be re-opened IMO because (a) the answer involves some settings on Virtualbox, which is running on Ubuntu 12.04 and (b) this seems likely to recur as more folks try Windows 8 – izx Jul 1 '12 at 9:21
@izx - whatever we do we need to be consistent. N.B. as per this Meta - this would fall into the off-topic side of installing OS's in virtualbox: – fossfreedom Jul 1 '12 at 9:38
@fossfreedom: thanks--especially for that meta Q--in retrospect it does seem that this is off-topic, since Uri's blog link indicates this is probably a platform-independent issue with Windows 8, rather than Virtualbox per se. – izx Jul 1 '12 at 9:41

The solution appears to be:

  1. In BIOS:
    • Enable VT-x
    • Enable VT-d
  2. In Virtualbox with Win8 VM off:
    • Enable PAE/NX
    • Enable VT-x
    • Enabled Nested Paging

as well make sure you are using IDE instead of SATA....... T[m}
