Like many, I've downloaded the W10 preview today (64bit edition) and plan to run it on a VM to check it out.

 

I thought about using Hyper-V, but as that screws up my playing blu-rays thanks to AMD's crappy drivers, I figured I'd use VirtualBox, but it seems I'm being stymied!

 

From what I understand, with Hyper-V enabled, VirtualBox will only let you create 32bit VM's, which is fine, but on my machine Hyper-V is NOT enabled at all, and it still won't let me make 64bit VM's.

 

This is bleedin' annoying, to say the least!

 

Now, I -have- had Hyper-V enabled previously on this machine, but when I discovered the blu-ray playback problem, I disabled it again; and I know it's thoroughly disabled as I've triple checked, even with bcdedit. It's completely off.

 

So, does anyone have any idea's why it's not playing ball?  I've tried toggling Hyper-V back on, and off again, and I've even uninstalled the Windows Phone 8 emulators that Visual Studio installed, but it's just not having it.  I'd rather not have to run the 32bit version of W10...

I've found in general that VirtualBox isn't as good as VMware Player. I'm having no issues with my installation of the x64 version in VMware Workstation 9 with Hyper-V turned on on my machine. Maybe switch to VMware?

yeah, i've heard that VirtualBox has become increasingly unstable as of late. I would recommend either trying to downgrade VirtualBox (i'm told that 4.3.12 is that last good version) or try using VMware Player instead

I have the x64 version of the Tech Preview running in OVB as I type this - however, I don't have Hyper-V running on the Windows 8.1 side; the conflict is between Hyper-V and OVB.

 

I have not created a Hyper-V VM of the Tech Preview yet - I am downloading the Tech Preview for Enterprises for that purpose (which will be installed in Server 2012R2).

 

I also have the "consumer" Tech Preview installed bare-metal on my Vista-era notebook (which is running swimmingly, by the by) - that is also x64.

 

Why have you not created a VM in Hyper-V yet?

As I said in my post, Hyper-V breaks blu-ray playback on my PC, thanks to AMD's crappy drivers.  If it's enabled, no BR movie playback, which is annoying as hell.

that seems really weird. I can't think of any reason why Hyper-V would effect blueray

It's a known problem that AMD have left unfixed for ages.  For some reason, the Catalyst drivers interfere with detection of a HDCP compliant display, so PowerDVD can no longer play back.

 

As soon as you disable Hyper-V, it all works again. :/

Hmm... VMWare Player is now installed, but it's telling me it can't start a 64bit VM.  Probably wants to reboot, I guess, but I'm not in a position where I can do that atm (my PC is running an IRC server for my friends).  Guess it'll have to wait till tomorrow now! :(

Good Keep posting for updates :)

 

Well, first thing to point out is that, as VBox's additions obviously won't install, performance is not optimum.  There is some mouse lag and no widescreen resolution modes due to the rather basic video drivers, but this is something Oracle are going to have to resolve.  There's also some minor crackling in the audio, but again, that's the VBox additions.

 

Haven't had time yet to play with the VMWare install, I'll do that this evening, after work!

Tried Virtualbox, forgot my processor does not support NX PAE bit, switched to secondary, again with ViBx forgot that that processor does not support virtualization. Said **** this and partitioned for dual-boot.

running VBOX here, latest version and the x64 iso of the Windows 10; previously i had Hyper-V installed and since Hyper-V lies under the host, it just uses ALL THE TIME the VT-X extension, resulting in no x64 support for VBOX. There are two know solutions for this: disabling Hyper-V and uninstalling; i found the lastest is the one that works for me but some have reported that the first worked.

 

Of course perf isn't going to be perfect, since there isn't (yet) the addictions, but since this is for me to tried it, know the features and what's under the hood, it's an OK situation for me.

Weirdly, today VBox is showing 64bit options...

 

Oh well, I decided to install it to both VM's so I can compare performance between the two! :)

Don't use virtualisation!

 

In future use native VHD boot, Im typing this from the preview installed on a vhdx right now on a UFEI Secure Boot PC.

You don't need imagex just create the vhdx, dism apply image Dism /apply-image /imagefile:N:\sources\install.wim /index:1 /ApplyDir:x:\

 

where x is your mounted vhdx drive and n is the path to your prieview iso wim

 

then bcdboot x:\windows where agaub x is where x is your mounted vhdx drive.

 

Finally reboot and select windows technical preview

If I wanted to do that, I could, but as I don't, I don't.

 

My PC has to host an IRC server whilst I'm using it, so I need my host OS up and running at the same time.  It also acts as the household media server for all our mobile devices and the XBox, so dual booting of VHD booting is not an option. (And no, I'm not going to buy a dedicated machine for that, mine does the job perfectly without additional costs.)

I'm running Win10 TP on VirtualBox and it works well enough, but, as noted, it can't install the guest additions. I'm either going to use VMware Workstation (which I recall buying a while back), VMware Player. Any updates on the performance of Win10 on either of those?

Have you ever tried AnyDVD HD to see if it "fixes" the HDCP , I know it isn't a long term answer, I was just curious if it "unbreaks" the problem

Works OK virtualized with Hyper-V on my Server 2012 R2u1 system.

No apparent performance issues so far.

Sorry, got sidetracked by the kids last night so didn't get chance. :/ Will go over it tonight.

Never tried it, no. Isn't that a commercial program?

 

Theoretically, I suppose it should as AnyDVD is meant to strip out DRM, but I've no idea if it actually does or not...

I'm running Windows 10 on VMware Fusion 7 - which for all intents and purposes is the Mac equivalent of VMware Workstation 11. Performance is perfectly fine.

Just installed it on VMware, works like a charm, & Now I am convinced to upgrade from Win7 to Win10.

Windows8/8.1 is another failure vista!

 

Here we go again. Vista paved the way for Win7, without it Win7 would of been just another XP. Just as Win8/8.1 paved the way for Win10. Now you guys will finally be able to see the Win8 goodness (and more) people like myself have been enjoying for the past ~2 years while everyone else was busy hating on (and unable to see past) the Start Screen/Modern UI. This is purely my opinion so take with a grain of salt.

Performance for me on VBox is good enough, main thing is I'm limited to a very small resolution, since the guest tools won't install that would let me use my monitor's native resolution.

Well said. You can like or dislike the Start screen, but Win8 made some very important under-the-hood improvements. One of my favorite is probably the much more intelligent file copying, where you could pause various copy jobs to speed up another one.
