How To Install Windows Longhorn In Virtualbox

I'm posting this under Longhorn 4074 inside VMware Workstation 8 (VMware Player's equivalent will do too as VMware Player is pretty much the same without advanced features like Snapshots.)

Make a new VM, call it what you want, set the OS to Windows XP Professional. Disable BIOS date sync because we'll be installing VMware tools, too, but to boot into Longhorn we must change the BIOS date.

As CaptainPeanut said, don't use SCSI for the virtual hard drive connection. VMware defaults to SCSI under Vista and 7 AFAIK, but anything before that defaults to IDE. I did this mistake on a physical machine. Windows XP has the same problem except you can fix it quite easily by slipstreaming SATA drivers.

Do the installation and boot into Longhorn. Make sure your BIOS date isn't sneakily changed by VMware Workstation.
When you've booted into Longhorn, you'll need to get rid of that timebomb (to show correct date). I have a patched Winlogon.exe for said build (by a BA member, unsure who it is) and a file replacer bundled in one ISO if you want it, just ask because I don't think BA will let me post it publicly regarding cracks.

When you've patched it, restart, change your BIOS date to today and boot. Shouldn't boot you off this time. Make a snapshot of this. Very important if you want to go back in time to when you patched it.
Get VMware Tools for Workstation 6 (Workstation 8 drivers will not work) and install as normal. It may take a while because Longhorn is slow at first.

When it's finally installed, make another snapshot, then restart. Again, shouldn't boot you off the desktop and to the login screen. VMware Tools will take a while, but not too long, to prepare itself and, well, work. At first you'll get an error telling you to upgrade VMware Tools, ignore it. VMware Tools in the 4074 VM will show a "No sign" in front of its icon, then will show a caution icon. When it gets to the caution icon, it'll allow you to resize the VM screen.

And you have a near-perfect Longhorn build! This build's version of IE has a download manager that doesn't work (on me) so download Firefox or Opera (Opera is recommended) on the host and drag it to the VM (it will work.) Change the compatibility mode of Opera's installer to Windows XP and you have a perfect browser, too.

Sorry for the long as hell post, too. And thank Microsoft Collection Book for the links. An awesome site, I'd say.

Inactive. I also don't have anything ROBLOX-related, anymore. Please don't ask.
